Method for preparing a chitosan-based porous layer The present invention relates to a method or preparing a chitosan-based, neutralized compressed porous layer, comprising the following steps: - a) a chitosan solution is prepared, - b) said solution is poured into a mould in order to form a layer, - c) the layer obtained in b) is lyophilized so as to obtain a porous layer, - d) said porous layer obtained in c) is compressed, - e) the compressed porous layer obtained in d) is neutralized by means of an NH 4 OH solution. It also relates to an implant comprising a layer obtained according to such a method. |
