HYDROXYAPATITE - CHITOSAN BIOCOMPOSITES
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2008, Vol 0, Issue
Abstract
Both samples of HAp form with chitosan and it’s useful forms (MKCh, chitosan lactate) well shaped 3-dimentional forms – sponges. The sponges can be used as implants in orthopedic surgery. 3-dimentional structures of HAp/chitosan composites are a good base for scaffolds productin.
