Hydrogels—three-dimensional, water-swollen polymer networks—are rapidly advancing the frontiers of biomedicine. Especially promising are injectable and self-healing hydrogels, which allow for minimally invasive delivery, in situ gelling, and adaptive responses to mechanical or biochemical stimuli.
Whether used for drug delivery, tissue regeneration, cell encapsulation, or hemostatic therapy, hydrogels are critical tools in today’s biomedical engineering arsenal.
In this article, we highlight seven leading U.S.-based companies that are redefining what hydrogels can do. These innovators are turning fluid materials into dynamic, smart structures that can heal, protect, and deliver therapy with precision.
