Abstract
The invention relates to a method for preparing a hydrogel type matrix comprising at least two contiguous zones with distinct stiffnesses, comprising a step to photopolymerize a solution comprising one or several polymerizable compounds and a photopolymerization initiator, by application of light onto the entire solution and at a different intensity in at least two zones of the solution, as a result of which a hydrogel matrix is obtained comprising at least two contiguous zones with distinct stiffnesses, characterized in that the photopolymerization step is done in the presence of a polymerization catalyst.
