[PMID: 38388050 DOI: 10.1016/j.carbpol.2024.121842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 01/15/2024] [Accepted: 01/18/2024] [Indexed: 02/24/2024]
Abstract
Chitosan has been extensively explored in food coatings. Still, its practical application is largely hampered by its conventional wet processing in acetic acid, whose residuals negatively impact food quality and safety. Here, we propose a new method to formulate chitosan coatings for food applications by avoiding organic acid processing and validate them on a cheese model. The procedure entails modifying a previously reported process based on HCl chitosan treatment and neutralising the resulting gel. The obtained chitosan is solubilised in water using carbonic acid that forms in situ by dissolving carbon dioxide gas. The reversibility of water carbonation allows for easy removal of carbonic acid residues, resulting in acid-free chitosan films and coatings. The performance of the coating was tested against state-of-the-art chitosan-based and polymeric coatings. We preliminarily characterised the films' properties (water stability, barrier, and optical properties). Then, we assessed the performance of the coating on Provolone cheese as a food model (mass transfer and texture profiles over 14 days). The work demonstrated the advantage of the proposed approach in solving some main issues of food quality and safety, paving the way for an effective application of chitosan in future food contact applications.

Abstract
Vesicles (liposomes and niosomes) are bilayer membranous capsules composed of amphiphilic molecules having aqueous phase in their interior and can encapsulate drug ingredients to act as drug delivery systems, a bio-membrane model, and so on. Vesicles also find their applications in cosmetics and foods industries since they can not only entrap water-soluble substances in their core, but also solubilize oily substances in the bilayer membrane. Almost half a century has passed since the discovery of vesicles by Bangham, and research on their basic properties and applications has been gaining momentum once again. In this article, the preparation and properties of vesicles (liposomes, niosomes) with excellent dispersion stability, especially formed in mixtures of amphiphilic molecules, are reported. Furthermore, the preparation of nano-sized silica hollow particles using vesicles as a structure-directing agent and their application to anti-reflection film are also described.

Abstract
In recent years, liposomes have gained increasing attention for their potential applications as drug delivery systems in the pharmaceutic, cosmetic and food industries. However, they have a tendency to aggregate and are sensitive to degradation caused by several factors, which may limit their effectiveness. A promising approach to improve liposomal stability is to modify liposomal surfaces by forming polymeric layers. Among natural polymers, chitosan has received great interest due to its biocompatibility and biodegradability. This review discussed the characteristics of this combined system, called chitosomes, in comparison to those of conventional liposomes. The coating of liposomes with chitosan or its derivatives improved liposome stability, provided sustained drug release and increased drug penetration across mucus layers. The mechanisms behind these results are highlighted in this paper. Alternative assembly of polyelectrolytes using alginate, sodium hyaluronate, or pectin with chitosan could further improve the liposomal characteristics. Chitosomal encapsulation could also ensure targeted delivery and boost the antimicrobial efficacy of essential oils (EOs). Moreover, chitosomes could be an efficient tool to overcome the major drawbacks related to the chemical properties of EOs (low water solubility, sensitivity to oxygen, light, heat, and humidity) and their poor bioavailability. Overall, chitosomes could be considered as a promising strategy to enlarge the use of liposomes.

Abstract
Some issues in pharmaceutical therapies such as instability, poor membrane permeability, and bioavailability of drugs can be solved by the design of suitable delivery systems based on the combination of two pillar classes of ingredients: polymers and lipids. At the same time, modern technologies are required to overcome production limitations (low productivity, high energy consumption, expensive setup, long process times) to pass at the industrial level. In this paper, a summary of applications of polymeric and lipid materials combined as nanostructures (hybrid nanocarriers) is reported. Then, recent techniques adopted in the production of hybrid nanoparticles are discussed, highlighting limitations still present that hold back the industrial implementation.

Abstract
Lipid nanoparticles (LNPs) have been widely applied in drug and gene delivery. More than twenty years ago, DoxilTM was the first LNPs-based drug approved by the US Food and Drug Administration (FDA). Since then, with decades of research and development, more and more LNP-based therapeutics have been used to treat diverse diseases, which often offer the benefits of reduced toxicity and/or enhanced efficacy compared to the active ingredients alone. Here, we provide a review of recent advances in the development of efficient and robust LNPs for drug/gene delivery. We emphasize the importance of rationally combining experimental and computational approaches, especially those providing multiscale structural and functional information of LNPs, to the design of novel and powerful LNP-based delivery systems.

Abstract
Micro- and nano-carrier formulations have been developed as drug delivery systems for active pharmaceutical ingredients (APIs) that suffer from poor physico-chemical, pharmacokinetic, and pharmacodynamic properties. Encapsulating the APIs in such systems can help improve their stability by protecting them from harsh conditions such as light, oxygen, temperature, pH, enzymes, and others. Consequently, the API's dissolution rate and bioavailability are tremendously improved. Conventional techniques used in the production of these drug carrier formulations have several drawbacks, including thermal and chemical stability of the APIs, excessive use of organic solvents, high residual solvent levels, difficult particle size control and distributions, drug loading-related challenges, and time and energy consumption. This review illustrates how supercritical fluid (SCF) technologies can be superior in controlling the morphology of API particles and in the production of drug carriers due to SCF's non-toxic, inert, economical, and environmentally friendly properties. The SCF's advantages, benefits, and various preparation methods are discussed. Drug carrier formulations discussed in this review include microparticles, nanoparticles, polymeric membranes, aerogels, microporous foams, solid lipid nanoparticles, and liposomes.

Abstract
Though vesicular delivery systems have been widely explored and reviewed, no comprehensive review exists that covers their development from the inception of the concept to its culmination in the form of regulated marketed formulations. With the advancement of scientific research in the field of nanomedicine, certain category of vesicular delivery systems have successfully reached the global market. Despite extensive research and highly encouraging results in a plethora of pathological conditions in the preclinical studies, translation of these nanomedicines from laboratory to market has been very limited. Aim of this review is to describe comprehensively the various colloidal delivery systems, focusing mainly on their conventional and advanced methods of preparation, different characterization techniques and main success stories of their journey from bench to bedside of the patient. The review also touches the finer nuances of the use of modern formulation approach of DoE (Design of Experiments) in their formulation and the status of regulatory guidelines for the approval of these nanomedicines.

Abstract
MNPs find numerous important biomedical applications owing to their high biocompatibility and unique magnetic properties at the bottom level. Among several other biomedical applications, MNPs are gaining importance in treating various kinds of cancer either as a hyperthermia agent alone or as a drug/gene carrier for single or combined therapies. At the same time, another type of nano-carrier with lipid bilayer, i.e. liposomes, has also emerged as a platform for administration of pharmaceutical drugs, which sees increasing importance as a drug/gene carrier in cancer therapy due to its excellent biocompatibility, tunable particle size and the possibility for surface modification to overcome biological barriers and to reach targeted sites. MLs that combine MNPs with liposomes are endowed with advantages of both MNPs and liposomes and are gaining importance for cancer therapy in various modes. Hence, we will start by reviewing the synthesis methods of MNPs and MLs, followed by a comprehensive assessment of current strategies to apply MLs for different types of cancer treatments. These will include thermo-chemotherapy using MLs as a triggered releasing agent to deliver drugs/genes, photothermal/ photodynamic therapy and combined imaging and cancer therapy.

Abstract
The chief objective of this research was to appraise liposomes embodying a bile salt, sodium glycocholate (SGC), as oral nanoscale drug delivery system to strengthen the bioavailability of a water-soluble and weakly penetrable pharmaceutical, notoginsenoside R1 (NGR1). NGR1-loaded liposomes were prepared with the improved supercritical reverse evaporation (ISCRPE) method and the preparation conditions were optimized with response surface methodology (RSM). The mean encapsulation efficiency (EE), particle size, and polydispersity index (PDI) of the optimized liposomal formulation (NGR1@Liposomes) were 49.49%, 308.3 nm, and 0.229, respectively. SGC-mediated liposomes (NGR1@SGC-Liposomes) were formulated based on the optimal preparation conditions and the mean EE, particle size, and PDI were 41.51%, 200.1 nm, and 0.130, respectively. The in vitro Caco-2 cellular uptake of fluorescent marker was increased by loading into NGR1@SGC-Liposomes as compared with the conventional liposomes. Furthermore, the intestinal permeability as well as the intestinal absorption of NGR1 were both significantly improved with NGR1@SGC-Liposomes as the nanovesicles. The in vivo pharmacokinetic study results showed that AUC0-t value of NGR1@SGC-Liposomes and NGR1@Liposomes was 2.68- and 2.03-fold higher than that of NGR1 aqueous solution, respectively. The AUC0-t of the NGR1@SGC-Liposomes group was significantly higher than that of NGR1@Liposomes. Thus, ISCRPE method is a feasible method for the preparation of water-soluble drug-loaded liposomes and bile salt-mediated liposomes may enhance the oral absorption of water-soluble and poorly permeable drugs.

Abstract
Encapsulation of proteins in nanoparticles (NPs) can greatly improve the properties of proteins such as their stability against denaturation and degradation by proteases, and branches out the applications of natural proteins from their intrinsic localizations and functions in living organisms for biomedical and industrial applications. We recently developed several methods to armor proteins in NPs with sizes from nanometers up to >100nm, batch by batch or one by one, covalently or noncovalently, for a wide range of applications from biocatalysis to bioimaging and drug delivery. In this chapter, we provide detailed protocols on these methods. Key steps of specific protocols are explained with particular examples to help other laboratories to adopt and modify these methods for their own purposes. The advantages and disadvantages of each method are summarized, and guidelines for choosing the right method for a given application, as well as the current challenges and future directions of this field, are discussed.

Abstract
It was found out that block copolymers of polystyrene and poly(4-vinylpyridine) with comparable lengths of blocks could be dissolved in a high-pressure reactor containing water phase saturated with carbon dioxide under high pressure at room temperature. This rather effective dissolution occurs due to a protonation of P4VP nitrogen-containing groups together with a plasticization of the polymer material to be dissolved by a compressed dense CO2 being contained in the autoclave. The selected block copolymers form rather monodispersed micelles with well-defined and reproducible spherical geometry. They apparently have a hydrophobic polystyrene core and a polycationic poly-4-vinylpyridine corona. The obtained micelles were characterized by various techniques such as DLS, AFM, TEM, and SEM. Further, it was revealed that the corona of such micelles could be decorated with Pd nanoparticles having the diameter around 3 nm.

Abstract
AIMS Developing safe and efficient nano vectors is critical for the success of siRNA therapy. MATERIALS & METHODS By encapsulating red fluorescent protein (RFP) with chitosan (CS), a dual-functional siRNA delivery nano vector, RFP@CS, has been synthesized. RESULTS RFP@CS has an optimum size of 7-23 nm for siRNA delivery; and the fluorescence of RFP, protected by CS coating, provides an excellent probe to track the delivery of siRNA. RFP@CS delivers siRNA efficiently into cells and the targeted gene could be completely silenced even after 48 h. No cytotoxicity or acute toxicity in mice was observed. CONCLUSION The high transfection efficacy and safety demonstrate RFP@CS is a promising nano vector for the gene therapy.

Abstract
Since the pioneering research of Bangham et al. in 1965, liposomes have attracted a large amount of interest as potential carriers of various bioactive molecules for clinical applications. However, scaling-up conventional methods of liposome preparation has been proven to be challenging. Compared with conventional methods, processes that use supercritical fluid (SCF)-CO2 require a reduced amount of organic solvent, are relatively fast and simple to perform, and yield stable and more uniform liposomes. A number of studies have demonstrated that SCF-CO2 methods might be suitable for industrial-scale manufacturing of liposomes. In this review there are two topics being discussed. We provide an overview of liposomal drug products and aim to describe the physicochemical properties of liposomes prepared using various SCF methods. We review all of the available literature on SCF-CO2-based liposomes and focus on the future applications of these innovative technologies in industrial-scale liposome preparation.

Abstract
The interest of the pharmaceutical industry in lipid drug delivery systems due to their prolonged release profile, biocompatibility, reduction of side effects, and so on is already known. However, conventional methods of preparation of these structures for their use and production in the pharmaceutical industry are difficult since these methods are usually multi-step and involve high amount of organic solvent. Furthermore, some processes need extreme conditions, which can lead to an increase of heterogeneity of particle size and degradation of the drug. An alternative for drug delivery system production is the utilization of supercritical fluid technique. Lipid particles produced by supercritical fluid have shown different physicochemical properties in comparison to lipid particles produced by classical methods. Such particles have shown more physical stability and narrower size distribution. So, in this paper, a critical overview of supercritical fluid-based processes for the production of lipid micro- and nanoparticles is given and the most important characteristics of each process are highlighted.

Abstract
We intended to combine the liposomal preparation and the layer-by-layer deposition to prepare a nanosized capsule. Chitosan (CHI) was deposited to form the cationic polymeric layer onto a negatively charged liposomal surface and further deposition was carried out using anionic polymers dextran sulfate (DXS) or deoxyribonucleic acid (DNA). zeta-Potentials of nanocapsules changed between positive and negative charges at each deposition. FE-TEM revealed that the liposome remained a spherical shape even after the layer-by-layer (LbL) deposition. The capsule wall showed a dramatic increase in stability against the surfactant Triton X-100 compared to a bare liposome, and the stability was controllable by the adsorption amount of the polymer. These suggest that the polymer multilayer was generated on the liposome surface by the layer-by-layer depositions of polysaccharides. The three kinds of chemical substances with different charges, 1-hydroxy pyrene-3,6,8-trisulfonic acid (HPTS), alendronate, and glucose, were encapsulated into nanocapsules and the release was suppressed by the polymeric capsule wall irrespective of charges. The release from DNA-deposited nanocapsules (liponano-CHI-DNA) was clearly increased by raising temperature from 25 to 60 degrees C. This indicates that the temperature-dependent release was achieved by applying DNA denaturation as a temperature-dependent "switch", which influenced the permeability of the capsule wall.

Abstract
A new dense gas process for the formation of liposomes has been developed: depressurization of an expanded solution into aqueous media (DESAM). The technique provides a fast and simple process for bulk liposome formation. As an alternative to current dense gas technologies, the DESAM process reduces the pressure requirements for liposome formation. Liposomes with diameters between 50 and 200 nm were formed. For all samples produced using ethanol as the solvent, the average effective diameter ranged from 119 to 207 nm. When chloroform was used as the solvent, the average effective diameter increased to 387 nm. The residual solvent volume fraction in the liposomal product was less than 4% v/v, which is approximately one-quarter of the value reported for some other dense gas liposome formation methods. The liposomal samples were stored after formation at 5 degrees C for up to 8 months, with the average effective diameter and polydispersity increasing by only 13% and 7%, respectively, indicating high stability of the formulations.

Abstract
The design and construction of effective delivery vectors for drugs is very important. We have discovered that octadecyl quaternized carboxymethyl chitosan (OQCMC) in combination with cholesterol (Chol) could form stable vesicles with structure similar to that of conventional liposomes prepared from phosphatidylcholine/cholesterol (PC/Chol). Compared to conventional liposomes, our polymeric liposomes formed by OQCMC/Chol have many excellent features, such as good physical and thermal stability, excellent solubility in water, and high effectiveness in drug encapsulation. Trans-activating transcriptional activator protein (TAT peptide) could be connected on the surface of cationic polymeric liposomes by using cross-linking reagent N-hydroxysuccinimidyl-3-(2-pyridyldithio) propionate (SPDP). Also, oil-soluble magnetic nanoparticles were used to verify the bilayer structure of the polymeric liposomes and their ability to solublize hydrophobic materials. Using different preparation methods, OQCMC/Chol could easily be made into nanoscale particles by encapsulating both hydrophilic and hydrophobic components. We have successfully prepared polymeric liposomes encapsulating quantum dots (QDs), superparamagnetic nanoparticles, or both. Vincristine was also encapsulated in the polymeric liposomes with high drug encapsulation efficiency (90.1%). Vincristine-loaded magnetic polymeric liposomes were stable in aqueous solution and exhibited slow, steady release action over 2 weeks under physiologic pH (7.4). This allows the use of multifunctional cationic polymeric liposomes, such as those developed here from modified chitosan, in various applications such as cancer diagnosis and treatment.

Abstract
The aim of this review paper is to compare the potential of various techniques developed for production of homogenous, stable liposomes. Traditional techniques, such as Bangham, detergent depletion, ether/ethanol injection, reverse-phase evaporation and emulsion methods, were compared with the recent advanced techniques developed for liposome formation. The major hurdles for scaling up the traditional methods are the consumption of large quantities of volatile organic solvent, the stability and homogeneity of the liposomal product, as well as the lengthy multiple steps involved. The new methods have been designed to alleviate the current issues for liposome formulation. Dense gas liposome techniques are still in their infancy, however they have remarkable advantages in reducing the use of organic solvents, providing fast, single-stage production and producing stable, uniform liposomes. Techniques such as the membrane contactor and heating methods are also promising as they eliminate the use of organic solvent, however high temperature is still required for processing.
