Abstract
Chitosan-based polymers have enormous structural tendencies to build bioactive materials with novel characteristics, functions, and various applications, mainly in liver tissue engineering (LTE). The specific physicochemical, biological, mechanical, and biodegradation properties give the effective ways to blend these biopolymers with synthetic and natural polymers to fabricate scaffolds matrixes, sponges, and complexes. A variety of natural and synthetic biomaterials, including chitosan (CS), alginate (Alg), collagen (CN), gelatin (GL), hyaluronic acid (HA), hydroxyapatite (HAp), polyethylene glycol (PEG), polycaprolactone (PCL), poly(lactic-co-glycolic) acid (PGLA), polylactic acid (PLA), and silk fibroin gained considerable attention due to their structure-properties relationship. The incorporation of CS within the polymer matrix results in increased mechanical strength and also imparts biological behavior to the designed PU formulations. The significant and growing interest in the LTE sector, this review aims to be a detailed exploration of CS-based polymers biomaterials for LTE. A brief explanation of the sources and extraction, properties, structure, and scope of CS is described in the introduction. After that, a full overview of the liver, its anatomy, issues, hepatocyte transplantation, LTE, and CS LTE applications are discussed.

Abstract
Chitosan and its allies have in multiple ways expanded into the medical, food, chemical, and biological industries and is still expanding. With its humble beginnings from marine shell wastes, the deacetylated form of chitin has come a long way in clinical practices. The biomedical applications of chitosan are truly a feather on its cap, with rarer aspects being chitosan’s role in tissue regeneration and artificial organs. Tissue regeneration is a highly advanced and sensitive biomedical application, and the very fact that chitosan is premiering here is an authentication of its ability to deliver. In this review, the various biomedical applications of chitosan are touched on briefly. The synthesis methodologies that are specific for tissue engineering and biomedical applications have been listed. What has been achieved using chitosan and chitosan composites in artificial organ research as well as tissue regeneration has been surveyed and presented. The lack of enthusiasm, as demonstrated by the very few reports online with respect to chitosan composites and artificial organs, is highlighted, and the reasons for this lapse speculated. What more needs be done to expand chitosan and its allies for a better utilization and exploitation to best benefit the construction of artificial organs and building of tissue analogs has been discussed.

Abstract
Disruption in the normal anatomy and physiology of the skin often leads to wound formation. Its healing is a pretty complex and dynamic biological process with different phases. While there are many biopolymers (and their derivatives) for wound healing purposes. One of the most popular, promising, progressive and attention-grabbing biopolymers is 'chitosan'. It is a polysaccharide biopolymer that has tremendous potential in augmenting the process of wound healing. Most importantly, the derivatives of chitosan have heavily attracted the scientific community's attention to employing them in various formulations for wound healing applications. The prime focus of the present review is to provide scientific and technological prospection about chitosan and its derivatives for wound healing activity, starting from 2010 to 2020. Besides, the review also focuses about toxicity, different formulations and products of chitosan that are currently under clinical trials for wound healing purposes are described. Through this review, we present evidence that abundantly confirms that there is a growing interest in the domain of wound healing using novel, inventive, useful and patent protected chitosan derivatives. We speculate the possibility of more patent protected chitosan derivatives in the future for wound healing applications.

Abstract
Aim: Our study investigated the feasibility of transdermal delivery of heparin, an anticoagulant used against venous thromboembolism, as an alternative to intravenous administration. Materials & methods: Skin was pretreated using ablative laser (Precise Laser Epidermal System [P.L.E.A.S.E.®] technology) for enhanced delivery of heparin. In vitro permeation studies using static Franz diffusion cells provided a comparison between delivery from 0.3% w/v heparin-loaded poloxamer gel and solution across untreated and laser-treated dermatomed porcine ear skin. Results: No passive delivery of heparin was observed. Laser-assisted delivery from solution (26.07 ± 1.82 μg/cm2) was higher (p < 0.05) than delivery from heparin gel (11.28 ± 5.32 μg/cm2). However, gel is likely to sustain the delivery over prolonged periods like a maintenance dose via continuous intravenous infusion. Conclusion: Thus, ablative laser pretreatment successfully delivered heparin, establishing the feasibility of delivering hydrophilic macromolecules using the transdermal route.

Antibacterial Collagen Composite Membranes Containing Minocycline. J Pharm Sci 2020; 110:2177-2184.

Abstract
Collagen membranes have been used as bioresorbable barrier membranes in guided tissue/bone regeneration. However, the collagen membranes currently used in clinics lack an active antibacterial function, although infection at surgical sites presents a realistic challenge for guided tissue/bone regeneration. In this study, we successfully prepared novel and advanced collagen composite membranes from collagen and complexes of heparin and chelates of minocycline and Ca2+ ions. These membranes were characterized for chemical structures, morphology, elemental compositions and tensile strength. In vitro release studies were conducted to evaluate the release kinetics of minocycline from these membranes. Agar disk diffusion assays were used to assess their sustained antibacterial capability against model pathogenic bacteria Staphylococcus aureus. The chemical and physical characterization confirmed the successful synthesis of minocycline-loaded collagen composite membranes, namely NCCM-1 and NCCM-2. Both membranes had weaker tensile strength as compared with commercial collagen membranes. They achieved sustained release of minocycline for at least 4 weeks in simulated body fluid (pH 7.4) at 37°C. Moreover, both membranes demonstrated potent sustained antibacterial effects against Staphylococcus aureus. These results suggested that the advanced collagen composite membranes containing minocycline can be exploited as novel guided tissue regeneration membranes or wound dressing by providing additional antibacterial functions.

Abstract
Diabetes mellitus causes severe impairment in the cutaneous wound healing process, which has led to extensive research striving to establish new treatments. In this work, we describe the effects of chitosan hydrogels functionalized with either unfractionated heparin or bemiparin (a low molecular weight heparin, LMWH) as topical treatments in an experimental diabetic wound healing model. Although wound morphometry showed similar values at the end of the study, microscopic analyses revealed impaired healing in diabetic animals in terms of inflammation and tissue formation. However, both types of loaded hydrogels accelerated inflammation resolution and improved the epithelialization process, while showing a neodermal thickness similar to that of nondiabetic animals. Immunohistochemistry analyses revealed an intermediate response in macrophage evolution between diabetic and nondiabetic controls in the treated groups, as well as enhanced collagenization and myofibroblast progression patterns. However, these changes were not accompanied by differences among groups in collagen I, III and TGF-β1 gene expression. Functionalized hydrogels improved diabetes-associated impaired wound healing, thus promoting the progression of the process and inducing the formation of high-quality cicatricial tissue. Although the beneficial healing effect observed after topical treatment with chitosan hydrogels loaded with bemiparin or unfractionated heparin was similar, the chitosan hydrogel loaded with bemiparin is the preferred choice as it exhibited high-quality tissue in the neoformed dermal tissue.

Abstract
In this paper, the results of a spectral and thermochemical study of the DNA polyplex formation with chitosan and the effect of ethidium bromide polyplexes, sodium dodecyl sulfate, n-octyltrimethyl ammonium bromide, poly(4-styrenesulfonic acid), and heparin on the stability of the complexes are considered. It has been established that chitosan forms thermodynamically stable complexes with ethidium bromide (EtBr), in which there exists one monomer unit of chitosan for two ethidium bromide ones. The interaction of ethidium bromide with chitosan leads to a charge exchange of the polymer surface. The impact of chitosan on the intercalated DNA-EtBr complex conditions a release of EtBr with a polyplex formation. The process of polyplex formation in the presence of ethidium bromide proceeds endothermically, and in its absence the reaction is exothermic. The polyplex particles formed from DNA after release of EtBr are larger and have a smaller charge, as compared to the polyplex particles obtained without ethidium bromide. It has been found that anionic compounds cause the degradation of polyplexes, and it can prove to be a significant obstacle for using chitosan polyplexes in transfection, since in the presence of heparin in the bloodstream, the complexes will break down before reaching the target.

Abstract
Chitin is a linear polysaccharide of N-acetylglucosamine, which is highly abundant in nature and mainly produced by marine crustaceans. Chitosan is obtained by hydrolytic deacetylation. Both polysaccharides are renewable resources, simply and cost-effectively extracted from waste material of fish industry, mainly crab and shrimp shells. Research over the past five decades has revealed that chitosan, in particular, possesses unique and useful characteristics such as chemical versatility, polyelectrolyte properties, gel- and film-forming ability, high adsorption capacity, antimicrobial and antioxidative properties, low toxicity, and biocompatibility and biodegradability features. A plethora of chemical chitosan derivatives have been synthesized yielding improved materials with suggested or effective applications in water treatment, biosensor engineering, agriculture, food processing and storage, textile additives, cosmetics fabrication, and in veterinary and human medicine. The number of studies in this research field has exploded particularly during the last two decades. Here, we review recent advances in utilizing chitosan and chitosan derivatives in different technical, agricultural, and biomedical fields.

Abstract
Wound management is a notable healthcare and financial burden, accounting for >$10 billion in annual healthcare spending in the United States. A multidisciplinary approach involving orthopaedic and plastic surgeons, wound care nursing, and medical and support staff is often necessary to improve outcomes. Orthopaedic surgeons must be familiar with the fundamental principles and evidenced-based concepts for the management of acute and chronic wounds. Knowledge of surgical dressings, negative pressure wound therapy, tissue expanders, dermal apposition, biologics, and extracellular matrices can aide practitioners in optimizing wound care.

Abstract
Abstract
Two grades of chitosan [chitosan 30000 g mol−1 (N-chitosan 30) and 250000 g mol−1 (N-chitosan 250)] were functionalized by the Kabachnik–Fields reaction. To obtain the highest phosphonic ester grafting rate (55% and 40% for the N-chitosan 30 and N-chitosan 250, respectively), the pH must be kept constant during the reaction (pH=5). Then, a partial hydrolysis of the ester functions was carried out in HCl medium to generate phosphonic acid functions up to 25% and 20% for the N-chitosan 30 and N-chitosan 250, respectively. It was shown that the grafting of phosphonic acids on chitosan significantly reduced the dynamic viscosity. Afterwards, electrochemical impedance measurements were performed in an aqueous solution (pH=5) in the presence of either N-chitosans or P-chitosans (3 wt.%). The two native N-chitosans were little adsorbed onto the carbon steel surface and the corrosion protection was low. In contrast, the impedance results in the presence of the 30000 g mol−1 phosphorylated chitosan (P-chitosan 30) evidenced the beneficial effect of grafted phosphonic acid on its adsorption on the steel surface. The lower efficiency of the 250000 g mol−1 (P-chitosan 250) was attributed to its high molecular weight which made difficult the interactions between the phosphonic groups and the metallic surface.

Abstract
Electrolytically deposited carbonate apatite coating demonstrates higher strength but weaker support for bone marrow stromal cell attachment than do biomimetically deposited coatings. It is hypothesized that the incorporation of chitosan will increase the biocompatibility of electrolytic coating while maintaining its original strength. To verify this hypothesis, we formed a hybrid calcium phosphate/chitosan coating through electrodeposition. We found that the incorporation of chitosan influenced calcium phosphate formation and crystallization. Moreover, coating thickness and surface roughness decreased with increasing chitosan concentration. Hybrid coating exhibited an increased dissolution rate in both acidic and neutral simulated physiologic solution, whereas no significant difference on adhesive strength was found between the hybrid and original coatings (P > 0.05). Most importantly, the calcium phosphate/chitosan coating proved to be a more favorable surface for goat bone marrow stromal cell attachment than an unincorporated coating (P < 0.01). Considering its economic and simple production, a hybrid calcium phosphate/chitosan coating is thought to be an attractive candidate for future applications.

Abstract
AbstractA high molecular weight chitosan was chemically modified to quantitatively incorporate quaternary ammonium groups. Its efficiency was evaluated in the liquid-solid separation for various liquors, and compared with the one of a polyelectrolyte usually used for this utilization. The performance of the liquid-solid separation was estimated through the determination of two parameters measured after the screening- settling of the mixture liquor/flocculating agent: the separation efficiency (EV) and the TS removal efficiency (ETS). Apart for liquor 6, TS removal was always better after an addition of functionalized chitosan. Furthermore, whatever the type of liquor, the distribution was modified by an increased presence of high-size particles when functionalized chitosan was added. Moreover, chitosan addition tended to homogenize the size of the particles, which could facilitate the choice of the liquid-solid separation process. This homogenization was particularly observed for the liquor initially highly dispersed in size, i.e. liquors 1, 4, 6 and 8.

Abstract
The present study describes the preparation of extracellular matrix (ECM; from porcine omentum) based chitosan composite films for wound dressing applications. The films were prepared by varying the ECM content, whereas, the amount of chitosan was kept constant. The interactions amongst the components of the films were analyzed by FTIR and XRD studies. The films were thoroughly characterized for surface hydrophilicity, moisture retention capability, water vapor permeability, mechanical and biocompatibility. FTIR study indicated that both chitosan and ECM were present in their native form and did not lose their activity. XRD analysis suggested composition dependent change in the crystallinity of the films. The mechanical properties suggested that the composite films had sufficient properties to be used for wound dressing applications. An increase in the ECM content resulted in better hydrophilicity of the films and hence better the moisture retention capacity and retardant water vapor transmission rate property of the composite films. The films were found to be biocompatible to both blood and adipose tissue derived stem cells. In gist, the prepared films may be explored as wound dressing materials.

Abstract
This study aimed to utilize micro-computed tomography (micro-CT) analysis to compare new bone formation in rat calvarial defects using chitosan/fibroin-hydroxyapatite (CFB-HAP) or collagen (Bio-Gide) membranes. Fifty-four (54) rats were studied. A circular bony defect (8 mm diameter) was formed in the centre of the calvaria using a trephine bur. The CFB-HAP membrane was prepared by thermally induced phase separation. In the experimental group (n=18), the CFB-HAP membrane was used to cover the bony defect, and in the control group (n=18), a resorbable collagen membrane (Bio-Gide) was used. In the negative control group (n=18), no membrane was used. In each group, six animals were euthanized at 2, 4 and 8 weeks after surgery. The specimens were then analysed using micro-CT. There were significant differences in bone volume (BV) and bone mineral density (BMD) (P<0.05) between the negative control group and the membrane groups. However, there were no significant differences between the CFB-HAP group and the collagen group. We concluded that the CFB-HAP membrane has significant potential as a guided bone regeneration (GBR) membrane.

Abstract
Severe ocular surface disorders can result in deficiency of limbal stem cells that is potentially associated with chronic inflammation, impaired vision and even blindness. Advanced stem cells deficiency requires reconstruction of the OS with autologous or allogeneic limbal stem cells. To address such deficiency, a limbal tissue biopsy is taken and limbal cells are expanded on a carrier, which then can be used for OS reconstruction. Human amniotic membrane - currently the most common carrier for transplantation of limbal epithelial stem cells - has the downsides of carrying the risk of disease transmission, limited transparency, variable and unstable quality and low mechanical strength. This article reviews the advantages and disadvantages of the established carrier materials for limbal stem cell transplantation, as well as discussing emerging alternatives, including carriers based on collagen, fibrin, siloxane hydrogel contact lenses, poly(ε-caprolactone), gelatin-chitosan, silk fibroin, human anterior lens capsule, keratin, poly(lactide-co-glycolide), polymethacrylate, hydroxyethylmethacrylate and poly(ethylene glycol) for their potential use in the treatment of limbal stem cell deficiency.

Abstract
Chitosan microparticles (CMPs) have previously been developed for topical applications to the eye, but their safety and efficacy in delivering proteins to the retina have not been adequately evaluated. This study examines the release kinetics of CMPs in vitro, and assesses their biocompatibility and cytotoxicity on retinal cells in vitro and in vivo. Two proteins were used in the encapsulation and release studies: BSA (bovine serum albumin) and tat-EGFP (enhanced green fluorescent protein fused to the transactivator of transcription peptide). Not surprisingly, the in vitro release kinetics were dependent on the protein encapsulated, with BSA showing higher release than tat-EGFP. CMPs containing encapsulated tat-EGFP were tested for cellular toxicity in photoreceptor-derived 661W cells. They showed no signs of in vitro cell toxicity at a low concentration (up to 1mgml(-1)), but at a higher concentration of 10mgml(-1) they were associated with cytotoxic effects. In vivo, CMPs injected into the subretinal space were found beneath the photoreceptor layer of the retina, and persisted for at least 8weeks. Similar to the in vitro studies, the lower concentration of CMPs was generally well tolerated, but the higher concentration resulted in cytotoxic effects and in reduced retinal function, as assessed by electroretinogram amplitudes. Overall, this study suggests that CMPs are effective long-term delivery agents to the retina, but the concentration of chitosan may affect cytotoxicity.

Abstract
A new type of collagen/chitosan/heparin matrix, fabricated by gelation of collagen/ chitosan with heparin sodium containing ammonia, was produced to construct livers by tissue engineering and regenerative engineering. The obtained collagen/chitosan/heparin matrix was found to be highly porous, swelled rapidly in PBS solution and was stable in vitro for at least 60 days in collagenase/lysozyme containing buffered aqueous solution (PBS, pH 7.4) at 37 degrees C. The collagen/chitosan/heparin matrix resulted in a superior blood compatibility compared to the ammonia-treated collagen and collagen/chitosan matrices. The morphology and behavior of the cells on the collagen/chitosan/heparin membrane were found to be similar to those on the collagen membrane but different from those on the collagen/chitosan membrane. Hepatocytes cultured on the collagen/chitosan/heparin matrices exhibited highest urea and triglyceride secretion functions 25 days post seeding. These results suggest that this collagen/chitosan/heparin matrix is a potential candidate for liver tissue engineering.

Abstract
Biopolymer blends between collagen and chitosan have the potential to produce cell scaffolds with biocompatible properties. However, the relationship between the molecular weight of chitosan and its effect on physical and biological properties of collagen/chitosan scaffolds has not been elucidated yet. Porous scaffolds were fabricated by freeze-drying the solution of collagen and chitosan, followed by cross-linking by dehydrothermal treatment. Various types of scaffolds were prepared using chitosan with various molecular weights and blending ratios. Fourier transform infrared spectroscopy proved that collagen and chitosan scaffolds at all blending ratios contained mainly electrostatic interactions at the molecular level. The compressive modulus decreased with increasing the concentration of chitosan. Equilibrium swelling ratios of approximately 6-8, determined in phosphate-buffered saline at physiological pH (7.4), were found in case of collagen-dominated scaffolds. The lysozyme biodegradation test demonstrated that the presence of chitosan, especially the high-molecular-weight species, could significantly prolong the biodegradation of collagen/chitosan scaffolds. In vitro culture of L929 mouse connective tissue fibroblast evidenced that low-molecular-weight chitosan was more effective to promote and accelerate cell proliferation, particularly for scaffolds containing 30 wt% chitosan. The results elucidated that the blends of collagen with low-molecular-weight chitosan have a high potential to be applied as new materials for skin-tissue engineering.

Abstract
Chitin-based materials and their derivatives are receiving increased attention in tissue engineering because of their unique and appealing biological properties. In this review, we summarize the biomedical potential of chitin-based materials, specifically focusing on chitosan, in tissue engineering approaches for epithelial and soft tissues. Both types of tissues play an important role in supporting anatomical structures and physiological functions. Because of the attractive features of chitin-based materials, many characteristics beneficial to tissue regeneration including the preservation of cellular phenotype, binding and enhancement of bioactive factors, control of gene expression, and synthesis and deposition of tissue-specific extracellular matrix are well-regulated by chitin-based scaffolds. These scaffolds can be used in repairing body surface linings, reconstructing tissue structures, regenerating connective tissue, and supporting nerve and vascular growth and connection. The novel use of these scaffolds in promoting the regeneration of various tissues originating from the epithelium and soft tissue demonstrates that these chitin-based materials have versatile properties and functionality and serve as promising substrates for a great number of future applications.

Abstract
Biomaterial implants are a promising strategy to replace neural tissue that is lost after traumatic nerve damage. Chitosan (Ch) is a suitable material for nerve implantation when it is used at a minimum amount of 2% (w/v). The goal of this study was to determine the best mixture of 2% Ch with gelatin (G) and poly(L-lysine) (PLL) for use in neural tissue engineering. Using different physicochemical approaches we showed that all mixtures formed polyelectrolyte complexes with distinct electrostatic interactions between their compounds. This gave rise to different gel morphologies, among which Ch + G exhibited a significantly smaller pore size, unlike Ch + G + PLL. However, thermal resistance to degradation and the wettability of the Ch-based films were not affected. Additionally, these differences affected glial cells growth in long-term (14 days) cultures performed on Ch-based films. Astrocytes and olfactory ensheathing cells proliferated on G and Ch + G films which induced both flattened and spindle cell morphologies. Meanwhile, cortical and hippocampal neurons were similarly viable in all studied films and significantly lower than those observed in controls. Lastly, neurites from dorsal root ganglia extended the most on Ch + G films. These results show that a Ch + G mixture is a promising candidate for use in neural tissue engineering.

Abstract
Despite the many advances in tissue engineering approaches, scientists still face significant challenges in trying to repair and replace soft tissues. Nature-inspired routes involving the creation of polymer-based systems of natural origins constitute an interesting alternative route to produce novel materials. The interest in these materials comes from the possibility of constructing multi-component systems that can be manipulated by composition allowing one to mimic the tissue environment required for the cellular regeneration of soft tissues. For this purpose, factors such as the design, choice, and compatibility of the polymers are considered to be key factors for successful strategies in soft tissue regeneration. More recently, polysaccharide-protein based systems have being increasingly studied and proposed for the treatment of soft tissues. The characteristics, properties, and compatibility of the resulting materials investigated in the last 10 years, as well as commercially available matrices or those currently under investigation are the subject matter of this review.

Abstract
Chitosan (Ch) and some of its derivatives have been proposed as good biomaterials for tissue engineering, to construct scaffolds promoting tissue regeneration. In this work we made composite films from Ch and mixtures of Ch with gelatin (G) and poly-l-lysine (PLL), and evaluated the growth on these films of PC12 and C6 lines as well as neurons and glial cells derived from cerebral tissue and dorsal root ganglia (DRG). C6 glioma cells proliferated on Ch, G, and Ch + G films, although metabolic activity was decreased by the presence of the G in the mixtures. NGF-differentiated PC12 cells, adhered preferentially on Ch and films containing PLL. Unlike NGF-treated PC12 cells, cortical and hippocampal neurons showed good adhesion to Ch and Ch + G films, where they extended neurites. Astrocytes adhered on Ch, Ch + G, and Ch + PLL mixtures, although viability decreased during the culture time. Olfactory ensheathing cells (OEC) adhered and proliferated to confluency on the wells covered with Ch + G films. Neurites from DRGs exhibited high extension on these films. These results demonstrate that Ch + G films have excellent adhesive properties for both neurons and regeneration-promoting glia (OEC). These films also promoted neurite extension from DRG, making them good candidates for tissue engineering of nerve repair.

Abstract
In this study, we investigated cellular biocompatibility in vitro and segmental bone defect repairing efficacy in vivo of a previously reported fibre-reinforced scaffold, nano-hydroxyapatite/collagen/poly (L-lactic acid) (PLLA)/chitin fibres (nHACP/CF). First, attachment, proliferation, and differentiation of the goat bone mesenchymal stem cells (GBMSCs) cultured on the nHACP/CF scaffolds were evaluated in vitro. The results showed that cells attached to the scaffolds well, and there was no significant difference in cell proliferation between cells on the scaffolds and cells on the polystyrene culture plates that were used as a control. The results also showed that alkaline phosphatase (ALP)/DNA of the cells cultured on the scaffolds was significantly higher than that on the control. The in vivo study compared the bone defect repairing efficacy of nHACP/CF scaffolds with that of autograft bone. Thirty-two adult male goats with 25-mm defects in their tibias at the same anatomic site were divided into four groups. The first group was implanted with the nHACP/CF with GBMSCs. The second group was implanted with autograft bone. The third group was implanted with the nHACP/CF. Nothing was implanted in the fourth group. Bone growth was evaluated by radiography, histology, and biomechanics. The results showed that although the nHACP/CF had new bone formation, it could not repair the defect fully while nHACP/CF with GBMSCs cultured and autograft bone could repair the segmental bone defect by 8 weeks after surgery, suggesting that nHACP/CF is an appropriate scaffold for bone tissue engineering.

Abstract
Molecular imaging enables the non-invasive assessment of biological and biochemical processes in living subjects. Such technologies therefore have the potential to enhance our understanding of disease and drug activity during preclinical and clinical drug development. Molecular imaging allows a repetitive and non-invasive study of the same living subject using identical or alternative biological imaging assays at different time points, thus harnessing the statistical power of longitudinal studies, and reducing the number of animals required and cost. Chitosan is a hydrophilic and non-antigenic biopolymer and has a low toxicity toward mammalian cells. Hence, it has great potential as a biomaterial because of its excellent biocompatibility. Conjugated to additional materials, chitosan composites result in a new class of biomaterials that possess mechanical, physicochemical and functional properties, which have potential for use in advanced biomedical imaging applications. The present review will discuss the strengths, limitations and challenges of molecular imaging as well as applications of chitosan nanoparticles in the field of molecular imaging.

Abstract
The molecular and mechanical characteristics of in situ degradation behavior of chitosan-polygalacturonic acid/hydroxyapatite (Chi-PgA-HAP) nanocomposite films is investigated using Fourier Transform Infrared spectroscopy (FTIR), Atomic Force Microscopy (AFM), and modulus mapping techniques for up to 48 days of soaking in cell culture media. The surface molecular structure of media-soaked samples changes over the course of 48 days of soaking, as indicated by significant changes in phosphate vibrations (1200–900 ) indicating apatite formation. Chitosan-Polygalacturonic acid polyelectrolyte complexes (PECs) govern structural integrity of Chi-PgA-HAP nanocomposites and FTIR spectra indicate that PECs remain intact until 48 days of soaking. In situ AFM experiments on media-soaked samples indicate that soaking results in a change in topography and swelling proceeds differently at the initial soaking periods of about 8 days than for longer soaking. In situ modulus mapping experiments are done on soaked samples by probing 1–3 nm of surface indicating elastic moduli of 4 GPa resulting from proteins adsorbed on Chi-PgA-HAP nanocomposites. The elastic modulus decreases by 2 GPa over a long exposure to cell culture media (48 days). Thus, as water enters the Chi-PgA-HAP sample, surface molecular interactions in Chi-PgA-HAP structure occur that result in swelling, causing small changes in nanoscale mechanical properties.

Abstract
FUNDAMENTOS: A quitosana é polímero derivado da quitina, com vários tipos de aplicação na área médica. OBJETIVO: Avaliar a biocompatibilidade de membranas de quitosana no subcutâneo de ratos. MÉTODOS: Foram utilizados 20 ratos "Wistar" machos, nos quais foram implantadas membranas de quitosana, na região mediana dorsal. Os animais foram sacrificados: sete, 15, 30 e 60 dias após a cirurgia, tendo sido avaliados clinicamente durante o período experimental e com fotodocumentação no momento do sacrifício. Após o sacrifício, as membranas e tecidos adjacentes foram removidos e preparados para exame histológico e morfométrico. RESULTADOS: Nenhum animal apresentou efeitos adversos que pudessem ser atribuídos à implantação das membranas. O exame histológico mostrou que as inclusões são lisas e homogêneas e não são colonizadas por células do hospedeiro, sendo circundadas por pseudocápsula composta por fibroblastos e células inflamatórias. A morfometria da pseudocápsula revelou espessura semelhante durante todo o período experimental (P>0,05). CONCLUSÃO: A quitosana pode ser opção para uso como implante não integrado. Novos estudos devem ser realizados para comprovar a biocompatibilidade a longo prazo.

Enhancing growth and proliferation of human gingival fibroblasts on chitosan grafted poly (epsilon-caprolactone) films is influenced by nano-roughness chitosan surfaces. JOURNAL OF MATERIALS SCIENCE.

Abstract
The bioactivity of poly (epsilon-caprolactone) (PCL) films is improved by grafting chitosan (CS) surfaces with various values of nano-roughness on PCL surfaces. To examine the effects of the design, growing human gingival fibroblasts (HGFs) on the films was conducted. Various values of nano-rough CS surfaces were cast using nano-rough PCL molds that had been fabricated using a solvent-etched technique. The features of nano-CS/PCL surfaces were characterized using an atomic force microscope (AFM) to observe the topography and to determine the value of centerline average roughness of a surface, R(a). The R(a) values of the nano-CS/PCL films were 36.8 +/- 1.6, 100.0 +/- 3.0, and 148 +/- 7.0 nm, while that of the smooth CS/PCL film was 12.5 +/- 1.6 nm. The growth and proliferation of HGFs on the films are elucidated by fluorescent staining and analyzed by MTT viability assay following three and 7 days of culture. The viability assay of the cells reveals that the growth rates of HGFs on both CS/PCL and nano-CS/PCL films significantly exceed (95% or more; P < 0.001) those of PCL on both days, demonstrating the improvement of the bioactivity of PCL films by grafting CS. Additionally, the growth rates and proliferations of HGFs on nano-CS/PCL films of roughness 100 and 148 nm markedly exceed (15% or more; P < 0.001) those on 36.8 nm nano-CS/PCL and CS/PCL films, after both periods of culturing, indicating that the high nano-roughness CS surfaces further enhance the growth rate of HGFs. In conclusion, markedly improving the bioactivity of PCL films by grafting CS is demonstrated. Moreover, high nano-roughness of nano-CS/PCL films can further accelerate the growth and proliferation of HGFs compared with those of CS/PCL films. This work presents a new concept for designing biomaterials in tissue engineering.

Abstract
Chitosan-silica xerogel hybrid membranes were fabricated using a sol-gel process and their potential applications in guided bone regeneration (GBR) were investigated in terms of their in vitro cellular activity and in vivo bone regeneration ability. TEM observation revealed that the silica xerogel was dispersed in the chitosan matrix on the nanoscale. The hybrid membrane showed superior mechanical properties to chitosan in the wet state and the rapid induction of calcium phosphate minerals in simulated body fluid, reflecting its excellent in vitro bone bioactivity. Osteoblastic cells were observed to adhere well and grow actively on the hybrid membrane to a level higher than that observed on the chitosan membrane. The alkaline phosphatase activity of the cells was also much higher on the hybrid than on the chitosan membrane. The in vivo study in a rat calvarial model demonstrated significantly enhanced bone regeneration using the hybrid membrane compared to that observed using the pure chitosan one. Histomorphometric analysis performed 3 weeks after implantation revealed a fully closed defect in the hybrid membrane, whereas there was only 57% defect closure in the chitosan membrane.

Abstract
Tissue engineering is an important therapeutic strategy for present and future medicine. Recently, functional biomaterial researches have been directed towards the development of improved scaffolds for regenerative medicine. Chitosan is a natural polymer from renewable resources, obtained from shell of shellfish, and the wastes of the seafood industry. It has novel properties such as biocompatibility, biodegradability, antibacterial, and wound-healing activity. Furthermore, recent studies suggested that chitosan and its derivatives are promising candidates as a supporting material for tissue engineering applications owing to their porous structure, gel forming properties, ease of chemical modification, high affinity to in vivo macromolecules, and so on. In this review, we focus on the various types of chitosan derivatives and their use in various tissue engineering applications namely, skin, bone, cartilage, liver, nerve and blood vessel.

Abstract
The aim of this study was to investigate the effects of collagen on the microstructure and biocompatibility of chitosan-collagen composite sponges fabricated by a freezing and drying technique. The study was categorized into four groups: Group I: collagen; Group II: chitosan; Group III: 1:1 (by wt) chitosan-collagen and Group IV: 1:2 (by wt) chitosan-collagen sponges. A mouse osteoblast cell line, MC3T3-E1, was cultivated on the sponges in a mineralized culture medium for 21 days. Microstructure of scaffolds and growth of cells on the sponges were examined using scanning electron and confocal laser scanning electron microscopes. Pore size was analysed from scanning electron microscope images using Image-Pro Plus image analysis software. Cell viability (MTT assay), alkaline phosphatase activity and levels of osteocalcin and calcium were monitored every 3 days and on days 15 and 21, respectively. It was found that the sponges were porous with average pore sizes of 80-100 microm. A combination of chitosan and collagen matrixes created a well defined porous microstructure and biocompatible scaffolds. Chitosan-collagen composite sponges promoted growth and differentiation of osteoblasts into the mature stage. To optimize application of the composite sponges in bone regeneration, the fabrication process must be improved to increase the pore size of the scaffolds.
