Abstract[English]
A method of printing a hydrogel-based device includes contacting a monomer, a crosslinker, a photoinitiator, and a precursor salt with a solvent to form an ink solution, printing the ink solution onto a substrate, exposing the ink solution to light, sufficient to form a hydrogel, and contacting the hydrogel with a reducing agent sufficient to precipitate nanoparticles from the precursor salt in the hydrogel.[French]
Un procédé d'impression d'un dispositif à base d'hydrogel comprend la mise en contact d'un monomère, d'un agent de réticulation, d'un photoinitiateur et d'un sel précurseur avec un solvant pour former une solution d'encre, l'impression de la solution d'encre sur un substrat, l'exposition de la solution d'encre à de la lumière, suffisante pour former un hydrogel, et la mise en contact de l'hydrogel avec un agent réducteur suffisant pour précipiter les nanoparticules à partir du sel précurseur dans l'hydrogel.
