Chitosan absorbable/biodegradable

KytoCel by Aspen, reported by Aspen (2014), is a highly absorbent dressing composed of natural, biodegradable acylated chitosan fibres, which bond with wound exudate to form a clear gel that locks in fluid, absorbs pathogens, and is conformable to the wound bed.

Pol 4ner films basing on ultra dispersed low-density polyethylene powder modified by the natural polysaccharide, chitosan have been obtained under the combined effect of high pressure and shear deformation. Their water-absorbent capacity and biodegradability are estimated... 

Thermomodified chitosan films are characterized by the absence of solubility in water, high moisture-absorbing ability, high strength and elasticity. At increasing the time of thermal treatment the stability of chitosan films to the process of enzymatic biodegradation also increases.
