In this rubric we present you scientific news from the world of chitin and chitosan. Monthly you can find recent publications. We hope to arouse your interest in this biopolymer or to help you out. If you have any comments or if you do chitin or chitosan research and you want to publish your article on this page,
Have fun browsing on our pages!
American start-up for chitosan wound care solutions PhD students in Maryland (University of Maryland and Robert H. Smith School of Business) found their own start-up to develop blood-clotting products. Already two products are in a development phase. A surgical spray and a sponge, both based on chitosan.
Have a look at published papers in march 2009.
In February chitosan research remains very active. After 83 articles in January 73 papers were published in the second month of the year 2009.
Starting in a new year, in January 2009 many articles about chitosan and its derivates were published. Here you have an overview about the top themes into the last month.

Flow Field-Flow Fractionation (Flow-FFF) is a powerful tool to separate molecules and particles in a range from 103 to 107Da and particles of nanometric size up to a few micrometers [1]. By coupling FFF to Multi-angle light scattering (MALS) it is possible to determine absolute molar masses (M) of molecules and to verify their aggregation. For macromolecules of an appropriate size the radius of gyration (rg) can be achieved [2]. The aim of our study was to investigate various chitosan types by applying Flow-FFF and MALS to their aqueous solutions.
