Chitin hemostasis
WebThe obtained CMCH microspheres (CMCH-MS) were non-cytotoxic, low hemolytic potential and biodegradable in the presence of lysozyme. In vitro blood clotting evaluation indicated that the porous microsphere network structures and the hydrophilicity of the CMCH could promote hemostasis due to the quick blood absorption and local concentration of ... WebChitin, one of the most abundant biopolymers, can be transformed into one-dimensional (1D) nanoparticles.27,28 Moreover, chitin is readily modifiable owing to the amino group in its repeating unit. The resulting nanoparticles can combine the surface-modified adhesion property with the biological advantages of the biopolymer. They are dispersible
