Abstract
The present invention relates to a method for preparing a chitosan-based matrix comprising the following steps:
- a) two separate chitosan porous layers obtained from lyophilization of layers of one or more solutions of chitosan are provided,
- b) the chitosan porous layers of a) are neutralized and washed,
- c) a face of each chitosan porous layer is acidified with an acid,
- d) a fiber reinforcement member is provided and positioned between the two acidified faces of the two chitosan porous layers,
- e) the two chitosan porous layers and the fiber reinforcement member are let to dry to obtain a matrix having the fiber reinforcement member embedded therein. The invention also relates to an implant comprising a matrix obtained according to such a method.
