Recent Advances in the Preparation, Antibacterial Mechanisms, and Applications of Chitosan

Journal of Functional Biomaterials, Journal Year: 2024, Volume and Issue: 15(11), P. 318 - 318

Published: Oct. 27, 2024

Chitosan, a cationic polysaccharide derived from the deacetylation of chitin, is widely distributed in nature. Its antibacterial activity, biocompatibility, biodegradability, and non-toxicity have given it extensive uses medicine, food, cosmetics. However, significant impact variations physicochemical properties chitosan extracted different sources on its application efficacy, as well considerable differences antimicrobial mechanisms under varying conditions, limit full realization biological functions. Therefore, this paper provides comprehensive review structural characteristics chitosan, preparation methods sources, mechanisms, factors influencing efficacy. Furthermore, we highlight latest applications derivatives across various fields. We found that use microbial extraction shows promise new method for producing high-quality chitosan. By analyzing chitosan-based materials (such nanoparticles, films, sponges, hydrogels) prepared using biomedicine, agriculture, cosmetics, expect these findings to provide theoretical support broader utilization

New Insights Into the Effects of Electrode Polarization of Chitosan on Graphene Nanomaterials

Advanced Materials Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 19, 2025

Abstract The efficient transfer of electrons between the electrode and analyte, influenced by polarization (EP), is a crucial yet often overlooked factor in assessing performance electrochemical systems. This study explores use chitosan as an EP suppressor for graphene oxide (GO) reduced (RGO) ferri/ferro cyanide redox probe, using cyclic voltammetry (CV) impedance spectroscopy (EIS) techniques. CV results indicate that GO has greater pseudocapacitance than RGO does, indicating abundance oxygen‐containing functional groups facilitate stronger interfacial interactions with chitosan. By reducing capacitive current, shown through EIS, sensitivity toward Fe 2+/3+ couple at double layer enhanced. These findings align density theory (DFT) calculations, which charge distortion favoring chitosan, thereby allowing more intrinsic electron within aromatic rings GO/RGO nanomaterials. research holds significant potential advancing development sensors energy storage devices.

Stabilization of Argan Oil Nanoemulsions Using Chitosan Extracted from Pink Shrimp Shells

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(5), P. 2394 - 2394

Published: Feb. 24, 2025

This study investigates the use of chitosan, extracted from pink shrimp shells, as a stabilizer for argan oil nanoemulsions. Chitosan was obtained through demineralization, deproteination, bleaching, deacetylation, and purification, then characterized potentiometric titration, viscometry, X-ray diffraction (XRD), scanning electron microscopy (SEM), purity assessments. The resulting chitosan used to stabilize nanoemulsions formulated with extra-virgin nonionic surfactant using phase inversion composition (PIC) method. stability nanoemulsion assessed light scattering, zeta potential, viscosity, pH measurements. exhibited high purity, deacetylation degree 88.34%, molecular weight 408.809 kDa, crystalline index 66.36%. significantly improved stability, maintaining droplet integrity over six months at 40 °C. Higher concentrations increased size, indicating strong polymer adsorption. These findings demonstrate potential waste-derived sustainable nanoemulsions, promoting effective bioactive compound delivery environmental sustainability.
