A method for preparing a hydrogel comprising mixing a solution of a polymer with a photoinitiator, where the polymer comprises multiple subunits each having a non-aromatic unsaturated functional group, and irradiating the mixture with visible light to produce the hydrogel. L'invention concerne un procédé de préparation d'un hydrogel consistant à mélanger une solution d'un polymère avec un photoinitiateur, le polymère comprenant plusieurs sous-unités ayant chacune un groupe fonctionnel insaturé non aromatique, et à irradier le mélange avec de la lumière visible pour produire l'hydrogel.
