TLDR
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose, and recent progress in chitin chemistry is quite noteworthy as mentioned in this paper.Abstract:
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose. It has become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields, and recent progress in chitin chemistry is quite noteworthy. The purpose of this review is to take a closer look at chitin and chitosan applications. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.read more

Controlled Degradability of Polysaccharide Multilayer Films In Vitro and In Vivo
Catherine Picart,Catherine Picart,Aurore Schneider,Olivier Etienne,Jérôme Mutterer,Pierre Schaaf,Christophe Egles,Nadia Jessel,Jean-Claude Voegel +8 more
TL;DR: The results suggest that polysaccharide multilayer films are of potential interest for in‐vivo applications as biodegradable coatings, and that degradation can be tuned by using chitosan of different molecular weights and by controlling film crosslinking.

Comparative adsorption studies of indigo carmine dye on chitin and chitosan.
TL;DR: D dye/chitosan interaction showed favorable enthalpic and entropic processes, reflecting thermodynamic stability of the formed complex, while dye/ chitin interaction showed an exothermicEnthalpic value and a highly nonfavorable entropics effect, resulting in a nonspontaneous thermodynamic system.

A simple equation for description of solute release I. Fickian and non-fickian release from non-swellable devices in the form of slabs, spheres, cylinders or discs
TL;DR: In this paper, a simple exponential relation Mt/M∞ = ktn is introduced to describe the general solute release behavior of controlled release polymeric devices, where Mt is the fractional release, t is the release time, k is a constant, and n is the diffusional exponent characteristic of the release mechanism.
