Abstract
Nanogels open up access to a wide range of applications and offer among others hopeful approaches for use in the field of biomedicine. This review provides a brief overview of current developments of nanogels in general, particularly in the fields of drug delivery, therapeutic applications, tissue engineering, and sensor systems. Specifically, cyclodextrin (CD)-based nanogels are important because they have exceptional complexation properties and are highly biocompatible. Nanogels as a whole and CD-based nanogels in particular can be customized in a wide range of sizes and equipped with a desired surface charge as well as containing additional molecules inside and outside, such as dyes, solubility-mediating groups or even biological vector molecules for pharmaceutical targeting. Currently, biological investigations are mainly carried out in vitro, but more and more in vivo applications are gaining importance. Modern molecular imaging methods are increasingly being used for the latter. Due to an extremely high sensitivity and the possibility of obtaining quantitative data on pharmacokinetic and pharmacodynamic properties, nuclear methods such as single photon emission computed tomography (SPECT) and positron emission tomography (PET) using radiolabeled compounds are particularly suitable here. The use of radiolabeled nanogels for imaging, but also for therapy, is being discussed.

Abstract
BACKGROUND There is an obvious correlation between ulcerative colitis and colorectal cancer, and the risk of colorectal cancer in patients with ulcerative colitis is increasing. Therefore, the combination therapy of anti-inflammatory and anti-tumor drugs may show promising to inhibit colon cancer. 5-aminosalicylic acid (5-ASA) with anti-inflammatory function is effective for maintaining remission in patients with ulcerative colitis and may also reduce colorectal cancer risk. Histone deacetylase (HDAC) plays an essential role in the progression of colon cancer. Butyric acid (BA) is a kind of HDAC inhibitor and thus shows tumor suppression to colon cancer. However, the volatile and corrosive nature of BA presents challenges in practical application. In addition, its clinical application is limited due to its non-targeting ability and low bioavailability. We aimed to synthesize a novel dual-prodrug of 5-ASA and BA, referred as BBA, to synergistically inhibit colon cancer. Further, based on the fact that folate receptor (FR) is over-expressed in most solid tumors and it has been identified to be a cancer stem cell surface marker in colon cancer, we took folate as the targeting ligand and used carboxymethyl-β-cyclodextrin (CM-β-CD) to carry BBA and thus prepared a novel inclusion complex of BBA/FA-PEG-CM-β-CD. RESULTS It was found that BBA/FA-PEG-CM-β-CD showed significant inhibition in cell proliferation against colon cancer cells SW620. It showed a pro-longed in vivo circulation and mainly accumulated in tumor tissue. More importantly, BBA/FA-PEG-CM-β-CD gave great tumor suppression effect against nude mice bearing SW620 xenografts. CONCLUSIONS Therefore, BBA/FA-PEG-CM-β-CD may have clinical potential in colon cancer therapy.

Abstract
Among the biodegradable and nontoxic compounds that can form nanoparticles for drug delivery, amphiphilic cyclodextrins are very promising. Apart from ionic cyclodextrins, which have been extensively studied and reviewed because of their application in gene delivery, our purpose is to provide a clear description of the supramolecular assemblies of nonionic amphiphilic cyclodextrins, which can form nanoassemblies for controlled drug release. Moreover, we focus on the relationship between their structure and physicochemical characteristics, which is crucial for self assembly and drug delivery. We also highlight the importance of the nanoparticle technology preparation for the stability and application of this nanodevice.

Abstract
Cyclodextrins (CDs) have brought a revolution in the pharmaceutical field over the last decade. Natural and modified CDs (α-CD and β-CD) have been studied and some have gained US FDA approval or achieved 'Generally Regarded as Safe' (GRAS) status. Another characteristic of CDs is the ease with which they can be induced to form supramolecular structures for its use in drug delivery. CDs, grafted or crosslinked with polymers, are now being developed into 'smart' systems for efficient targeted drug delivery, especially for hydrophobic drugs. Amphiphilic CDs have the ability to form nanospheres or nanocapsules via a simple nanoprecipitation technique. This review deals with different types of CDs, and their efficacy, physicochemical properties and transformation into nanoparticles with interesting in vitro and in vivo applications.

Abstract
A variety of cyclodextrin-based molecular structures, with substitutions of either primary or secondary faces of the natural oligosaccharide macrocycles of α-, β-, or γ-cyclodextrins, have been designed towards innovative applications of self-assembled cyclodextrin nanomaterials. Amphiphilic cyclodextrins have been obtained by chemical or enzymatic modifications of their macrocycles using phospholipidyl, peptidolipidyl, cholesteryl, and oligo(ethylene oxide) anchors as well as variable numbers of grafted hydrophobic hydrocarbon or fluorinated chains. These novel compounds may self-assemble in an aqueous medium into different types of supramolecular nanoassemblies (vesicles, micelles, nanorods, nanospheres, and other kinds of nanoparticles and liquid crystalline structures). This review discusses the supramolecular nanoarchitectures, which can be formed by amphiphilic cyclodextrin derivatives in mixtures with other molecules (phospholipids, surfactants, and olygonucleotides). Biomedical applications are foreseen for nanoencapsulation of drug molecules in the hydrophobic interchain volumes and nanocavities of the amphiphilic cyclodextrins (serving as drug carriers or pharmaceutical excipients), anticancer phototherapy, gene delivery, as well as for protection of instable active ingredients through inclusion complexation in nanostructured media.

Abstract
Treatment and management of diseases of the posterior segment of the eye such as diabetic retinopathy, retinoblastoma, retinitis pigmentosa, and choroidal neovascularization is a challenging task due to the anatomy and physiology of ocular barriers. For instance, traditional routes of drug delivery for therapeutic treatment are hindered by poor intraocular penetration and/or rapid ocular elimination. One possible approach to improve ocular therapy is to employ nanotechnology. Nanomedicines, products of nanotechnology, having at least one dimension in the nanoscale include nanoparticles, micelles, nanotubes, and dendrimers, with and without targeting ligands. Nanomedicines are making a significant impact in the fields of ocular drug delivery, gene delivery, and imaging, the focus of this review. Key applications of nanotechnology discussed in this review include a) bioadhesive nanomedicines; b) functionalized nanomedicines that enhance target recognition and/or cell entry; c) nanomedicines capable of controlled release of the payload; d) nanomedicines capable of enhancing gene transfection and duration of transfection; f) nanomedicines responsive to stimuli including light, heat, ultrasound, electrical signals, pH, and oxidative stress; g) diversely sized and colored nanoparticles for imaging, and h) nanowires for retinal prostheses. Additionally, nanofabricated delivery systems including implants, films, microparticles, and nanoparticles are described. Although the above nanomedicines may be administered by various routes including topical, intravitreal, intravenous, transscleral, suprachoroidal, and subretinal routes, each nanomedicine should be tailored for the disease, drug, and site of administration. In addition to the nature of materials used in nanomedicine design, depending on the site of nanomedicine administration, clearance and toxicity are expected to differ.

Abstract
This research is aimed to develop a kind of hollow nanosphere based on β-cyclodextrin-grafted α, β-poly(aspartic acid) (β-CD-graft-PAsp) as drug carrier to enhance the stability of camptothecin (CPT) in aqueous media. Firstly, mono(6-(2-aminoethyl) amino-6-deoxy)-β-cyclodextrin (β-CDen) was synthesized by a substitution reaction between mono-6-deoxy-6-(p-tolylsulfonyl)-β-cyclodextrin (6-OTs-β-CD) and ethylenediamine; and then, the five-member rings in poly(L-succinimide) (PSI) were successively opened by β-CDen to obtain β-CD-graft-PAsp. The synthesized β-CD-graft-PAsp was found to form the unique hollow nanosphere with the internal hole of about 17 nm and many β-CD cavities of 0.7 nm interspersed on the shell. The drug-loading behavior of the hollow nanosphere was also evaluated by using CPT as guest molecule of β-CD. It was worth of note that the β-CD-graft-PAsp hollow nanosphere as carrier enhanced the stability of CPT in aqueous media, and the CPT from the β-CD-graft-PAsp hollow nanosphere displayed a sustained release profile and hence resulted in the essential decrease of cytotoxicity to L929 cell line. Furthermore, almost no cytotoxicity of the β-CD-graft-PAsp is desirable for the application of drug carrier. As a result, the β-CD-graft-PAsp hollow nanosphere showed a great potential as the carrier of CPT.

Abstract
As the biosafety of nanotechnology becomes a growing concern, the in vivo nanotoxicity of nanoparticles (NPs) has been drawn an increasing attention. Titanium dioxide nanoparticles (TiO(2)-NPs) have been developed for versatile use, but the pharmacokinetics of intravenously administered TiO(2)-NPs have not been investigated extensively. In the present study, the rutile-type TiO(2)-NPs with a size about 20nm were labeled with CF680 and (125)I. The labeled TiO(2)-NPs were injected in mice or rats with the concentration of 1mg/ml and the dose of 10mg/kg body weight and their tissue distribution and excretion were investigated by using ex vivo fluorescent imaging, γ-counter and TEM. The results indicated that the TiO(2)-NPs mainly accumulated in liver and spleen and could be retained for over 30days in these tissues due to the phagocytosis by macrophages. The excretion assay found that the excretory rate of TiO(2)-NPs through urine was higher than that of feces, indicating that renal excretion was the main excretion pathway of TiO(2)-NPs. Overall results of the present study provided important information on distribution and excretion of TiO(2)-NPs in vivo, which would greatly promote the pharmacokinetics and in vivo nanotoxicity research of TiO(2)-NPs.

Abstract
Poly(γ-benzyl-L-glutamate) (PBLG) derivatives are synthetic polypeptides for preparing nanoparticles with well controlled surface properties. The aim of this paper was to investigate the biodistribution of pegylated PBLG in rats. For this purpose, nanoparticles were prepared by a nanoprecipitation method using mixtures of different PBLG derivates, including a pegylated derivate to avoid mononuclear phagocyte system uptake. The morphology, size distribution, and surface charge of the nanoparticles were investigated as a function of the amount of polymer employed for the preparation. Moderately polydispersed nanoparticles (polydispersity index less than 0.2) were obtained. Their size increased with polymer concentration. The zeta potential values were negative whatever the formulations. The availability of polyethylene glycol chains on the nanoparticles’ surface was confirmed by measuring the decrease in bovine serum albumin adsorption. For in vivo distribution studies, pegylated and nonpegylated nanoparticles were prepared with polymer mixtures containing PBLG-fluorescein isothiocyanate and imaged by fluorescence microscopy to measure their accumulation in liver and spleen tissues of rats after intravenous administration. Injection of stealth formulations resulted in negligible fluorescence in liver and spleen compared with nonpegylated formulations, which suggests that these nanoparticles are promising candidates as a stealth-type long-circulating drug carrier system and could be useful for active targeting of drugs while reducing systemic side effects.

Abstract
Cationic solid lipid nanoparticles (SLN) can bind DNA directly via ionic interaction and mediate in vitro gene transfection. However, toxicity is still an obstacle, which is strongly dependent on the cationic lipid used. In the present study, a novel single-tailed cationic lipid, 6-lauroxyhexyl lysinate (LHLN), was synthesized and used as a modifier to prepare stable SLN-DNA complexes by a nanoprecipitation method. The commonly used cationic lipid cetyltrimethylammonium bromide (CTAB) modified SLN-DNA formulation served as a contrast. These two formulations were characterized and compared in terms of morphology, particle size, surface charge, DNA binding capacity, release profile, cytotoxicity, and transfection efficiency. The LHLN SLN-DNA complexes had a similar spherical morphology, a relatively narrow particle size distribution and a more remarkable DNA loading capability compared to the CTAB ones. Most importantly, LHLN modified SLN had a higher gene transfection efficiency than the naked DNA and CTAB ones, which was approximately equal to that of Lipofectamine-DNA complexes, and a lower cytotoxicity compared with CTAB-SLN and Lipofectamine 2000. Thus, the novel cationic SLN can achieve efficient transfection of plasmid DNA, and to some extent reduce the cytotoxicity, which might overcome some drawbacks of the conventional cationic nanocarriers in vivo and may become a promising non-viral gene therapy vector.

Abstract
A major obstacle in the development of polymeric nanoparticles (NPs) as effective drug delivery vesicles is the rapid clearance from blood. In order to realize a significant prolongation in blood circulation, a combinatorial design, covalent attachment of polyethylene glycol (PEG) to polylactic acid (PLA) and physical adsorption of water-soluble chitosan (WSC) to particle surface, has been developed for surface modification of PLA NPs. Two types of WSC, cationic partially deacetylated chitin (PDC) and anionic N-carboxy propionyl chitosan sodium (CPCTS) were investigated. All the NPs formulated in the size range of 100-200nm were prepared by a modified w/o/w technique and physicochemically characterized. In vitro phagocytosis by mouse peritoneal macrophage (MPM), in vivo blood clearance and biodistribution following intravenous administration in mice, of these NPs labeled with 6-coumarin, were evaluated. The presence of WSC, whether alone or with PEG, highly improved the surface hydrophilicity as well as suspension stability of NPs. Their surface charge was greatly affected by the WSC coating, being close to neutrality for PEG/PDC NPs and highly negative in the case of PEG/CPCTS NPs. In comparison to NPs treated with PEG or WSC alone, the synergistic action of PEG and WSC strongly inhibited the macrophage uptake and extended the circulation half-life (t(1/2)) with concomitant reduced liver sequestration. Particularly, PEG/PDC NPs showed the most striking result with regard to their performance in vitro and in vivo. Calculated t(1/2) of PEG/PDC NPs and PEG/CPCTS NPs was 63.5h and 7.1h, respectively, much longer than that of control PEG/PVA NPs (1.1h). More WSC materials need to be evaluated, but the present data suggest that, a combinatorial coating of PEG and PDC greatly prolongs the systemic circulation of NPs and represents a significant step in the development of long-circulating drug delivery carriers.
