The disclosure relates to a biomaterial that comprises an aqueous phase, polymer network, a second polymer included in said disclosure invention more particularly relates to a biomaterial including an aqueous phase and a first polymer network made of a first proteic or saccharidic polymer or a mixture of first proteic and saccharidic polymers, wherein the first polymer network and the aqueous phase define a first gel (A), the biomaterial including: a second proteic or saccharidic polymer or a mixture of the second proteic and saccharidic polymers, either in solution in the aqueous phase of the gel (A) or in the form of a gel (B), and a first enzyme for degrading said second polymer or second polymer network. The disclosure also relates to a method for making biomaterials, and to the uses of the biomaterial particularly for releasing active substances, and to a device for the controlled release of active substances that include the biomaterial. The disclosure can particularly be used in the field of cosmetics and pharmaceuticals.

Biomaterial for the controlled delivery of ingredients

The invention relates to a biomaterial which can successively carry out a solution/gel transition then a gel/solution transition with given kinetics, said biomaterial comprising at least one monomer which may form polymers, at least one enzyme which may decompose said polymers and, optionally, an enzyme which may form covalent bonds between said monomers. The invention further relates to a method for the production of said biomaterial.
