Title
(EN) METHOD TO SYNTHESIZE GELATIN METHACRYLOYL HYDROGELS
(FR) PROCEDE DE SYNTHESE D`HYDROGELS DE METHACRYLOYLE DE GELATINE
Abstract
(EN) A method for synthesizing hydrogels comprises dissolving a gelatin in a first solvent to form a first solution, methacrylating the first solution using a methacrylating agent to form a solution containing dissolved gelatin methacryloyl, precipitating the gelatin methacryloyl from the solution by adding a second solvent and isolating the precipitated gelatin methacryloyl. The method may further comprise dissolving the precipitated gelatin methacryloyl in a third solvent to remove the second solvent.
