Special Issue Information

Dear Colleagues,

Being the second most abundant natural polymer on Earth, chitosan possesses many unique chemical, structural and biological properties that make it attractive for numerous biomedical applications. Chitosan can be easily fabricated into different nanomaterials or nanocomposites, such as nanofibers, nanoparticles, gels, micelles and liposomes, to suit different needs. In addition, numerous approaches developed for chitosan have also overcome limitations in biomedical fields by using chitosan derivatives, composites or nanocomposites. Although numerous papers have discussed the application of chitosan nanomaterials in biomedical fields, they are found dispersed in different scientific journals. Consequently, this Special Issue aims to provide a broad coverage of recent research progress or up-to-date reviews addressing various aspects in this field. With this Special Issue, we aim to provide the readers with the opportunity to learn about different facets of biomedical research using chitosan-based nanomaterials. For the authors, this Special Issue will provide a unique opportunity to make their research results more visible to the scientific community. This Special Issue is seeking contributions from researchers to discuss all application aspects of chitosan nanomaterials in tissue engineering, regenerative medicine, drug delivery, wound healing and diagnostics. Critical reviews by experts in these fields are also welcomed.

The aim of the present work is to evaluate the preparation of sunscreen emulsions based on chitosan (CS) nanoparticles with annatto, ultrafiltrated (UF) annatto, saffron, and ultrafiltrated saffron. Ionic gelation was used for the preparation of chitosan nanoparticles, while their morphological characteristics and physicochemical properties were evaluated via Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and dynamic light scattering (DLS). Results showed that the prepared nanoparticles ranged from ~150 to ~500 nm and had a spherical or irregular shape. In the case of annatto and UF annatto, due to the formation of H-bonds, the sunscreen agents were amorphously dispersed within CS nanoparticles, while in the case of saffron and UF saffron, crystalline dispersion was observed. All encapsulated materials had good thermal stability as well as color stability. In a further step, sunscreen emulsions were prepared based on the formed CS-sunscreen nanoparticles and evaluated for their stability in terms of pH and viscosity, along with their ultraviolet (UV) radiation protection ability in terms of sun protection factor (SPF). All prepared emulsions showed low cytotoxicity and good storage stability for up to 90 days, while minimum sunscreen protection was observed with SPF values varying from 2.15 to 4.85. Full article

This review discusses different forms of nanomaterials generated from chitosan and its derivatives for controlled drug delivery. Nanomaterials are drug carriers with multiple features, including target delivery triggered by environmental, pH, thermal responses, enhanced biocompatibility, and the ability to cross the blood-brain barrier. Chitosan (CS), a natural polysaccharide largely obtained from marine crustaceans, is a promising drug delivery vector for therapeutics and diagnostics, owing to its biocompatibility, biodegradability, low toxicity, and structural variability. This review describes various approaches to obtain novel CS derivatives, including their distinct advantages, as well as different forms of nanomaterials recently developed from CS. The advanced applications of CS-based nanomaterials are presented here in terms of their specific functions. Recent studies have proven that nanotechnology combined with CS and its derivatives could potentially circumvent obstacles in the transport of drugs thereby improving the drug efficacy. CS-based nanomaterials have been shown to be highly effective in targeted drug therapy. Full article

Abstract: The rapid development of nanomaterials has provided wonderful opportunities for the creation of new pharmaceutical preparations. As a drug carrier, nanomaterials integrate multiple functions into itself, including target delivery, environmental response triggered, biocompatibility and so on. Chitosan (CS), a natural biological polysaccharides, is a well-known promising drug delivery vector for therapeutics and diagnostics, owing to its biocompatibility, biodegradable, low toxicity and structure-modifiable. CS and its derivatives have been developed into various pharmaceutical applications such as colon target drug delivery, mucosal delivery, cancer therapy and so on. This review article discusses different forms of nanomaterials for drug delivery by using various approaches for the preparation of chitosan derivatives or nanocomposites.
