Article Abstract
Biologically derived polymers, such as chitosan, have gained attention as sustainable alternatives to synthetic materials for food and biomedical applications. Fungal-derived chitosan offers notable advantages over crustacean-based chitosan, including a renewable origin and lower allergenic potential. In this study, chitosan was extracted from fungal biomass through a sequential process comprising demineralization, deproteinization, and deacetylation. The extracted material was characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), zeta potential measurement, dynamic light scattering (DLS), and color analysis. Compared to commercial chitosan, the fungal chitosan exhibited lower crystallinity and thermal stability, as well as a more porous surface morphology. Its degree of deacetylation and surface charge suggest promising potential for use in biodegradable films and functional materials. These findings highlight the feasibility of using fungal biomass as a sustainable and valuable source of chitosan for technological applications.

Persistent bacterial infections remain a major challenge in wound management. Although drug-loaded wound dressings have gained increasing attention, their therapeutic efficacy is often hindered by uncontrolled drug release and a lack of electrical signal responsiveness. Herein, an antibacterial dressing (CCS-PC) with electroactivity and stimulus-responsive drug release properties was fabricated via electro-assembly, wherein chitosan and ciprofloxacin hydrochloride (CIP) were co-deposited onto polypyrrole (PPy)-coated gauze.

In this study, a novel hybrid hydrogel incorporating a scandium-based metal-organic framework (scandium-integrated MOF-hydrogel hybrid) was developed using scandium nitrate, 1,4-naphthalenedicarboxylic acid, oxidized pectin, and chitosan. The synthesized scandium-integrated MOF-hydrogel hybrid demonstrated remarkable dual-functionality in both the adsorption of hazardous dye pollutants and the inhibition of pathogenic bacteria commonly found in wastewater. Characterization of the scandium-integrated MOF-hydrogel hybrid was performed using FT-IR, XRD, SEM, EDAX, CHNO elemental, BET, and XPS analyses, confirming successful MOF integration and a porous, reactive surface.

Tacrolimus belongs to the BCS class-II drug family and exhibits poor water solubility, which leads to poor bioavailability. Furthermore, since tacrolimus is an immunosuppressant, it is essential to maintain its therapeutic concentration for a greater period of time to confirm its effectiveness against transplant rejection. Therefore, to achieve the objective of the sustained release of the drug with a suitable amount of entrapment efficiency, pH-sensitive tacrolimus-loaded superabsorbent hydrogels using chitosan have been prepared.
