Some polymeric devices, as described herein, can be made of a first layer and a second layer bonded together with one or more microfluidic channels defined internal to the device. The first layer and the second layer may each include a substrate and a polymer bonded to the substrate. The two layers may be bonded through a polymer network that interpenetrates the polymers in the first and second layers. This disclosure also describes methods of bonding together polymeric articles. The methods include diffusing polymerizable monomers and radical forming initiators into the surfaces of one or both of the polymers, putting the surfaces into contact, and initiating polymerization to create a polymer network that interpenetrates the polymers.

The present disclosure provides a photopolymer composition and the applications thereof. The photopolymer composition comprises: 5 weight percent to 15 weight percent of gelatin methacrylate (GelMA), 0.1 weight percent to 5 weight percent of silanized biologically active additive, 0.1 weight percent to 5 weight percent of photoinitiator, and 75 weight percent to 95 weight percent of a solvent. Compared to a conventional hydrogel, the hydrogel prepared from the photopolymer composition of the present disclosure has improved compressive strength, mechanical strength and stability. Accordingly, the hydrogel is applicable to biomedical research and tissue repair.
