Asymmetric wettable polycaprolactone-chitosan/chitosan oligosaccharide nanofibrous membrane as antibacterial dressings

Carbohydrate Polymers, 2023
Wound infection and inflammation hinder the process of wound healing and bother human beings chronically. As a naturally degradable macromolecule, chitosan (CS) has been widely used in antibacterial wound dressings. However, the antibacterial property of chitosan is inhibited by its water insolubility.

Synthesis of silica chitosan oligosaccharides nanoparticles

Agro Productividad, 2023
Objective: To obtain chitosan oligosaccharides (COS) and evaluate COS uses for the obtention of nanosystem based on silica as vehicle and compare the COS-silica nanosystem with the chitosan (Chi) precursor system as Chitosan-silica nanosystems. Design/methodology/approach: A combination of hydrolysis chemical and mechanical (microwave assisted) were ...

Chitosan oligosaccharide (COS): An overview

International Journal of Biological Macromolecules, 2019
The frequently studied polysaccharide, chitosan oligosaccharide/chitooligosaccharide (COS) is the major degradation product of chitosan/chitin via chemical hydrolysis or enzymatic degradation involving deacetylation and depolymerization processes.

Cellobiohydrolases Produce Different Oligosaccharides from Chitosan

Biomacromolecules, 2016
Chito-oligosaccharides (COSs) are bioactive molecules with interesting characteristics; however, their exploitation is still restricted due to limited amounts accessible with current production strategies. Here we present a strategy for the production of COSs based on hydrolysis of chitosan by using readily available glycosidases.

Impacts of chitosan oligosaccharide (COS) on angiogenic activities

Microvascular Research, 2021
It has been proved that chitosan oligosaccharide (COS) has a more favorable therapeutic applications such as wound healing and anti-tumor treatment, and can affect angiogenesis. For better understanding the effect of COS on angiogenic activities at cellular level, COS with different concentration and degree of polymerization (DP) were used to culture ...
