Biomedical polymers sponges

Chitosan is a very useful polymer for biomedical applications because of its biocompatibility, biodegradability and low toxicity. Chitin has also been described as biocompatible and biodegradable, and has found applications for specific purposes, such as sponges and bandages for the treatment of wounds and suture threads. However, it has generally received less attention than chitosan, because of its insolubility in water and low reactivity.
