The treatment of diabetic wounds remains a great challenge for medical community. Here, we present novel structural color supramolecular hydrogel patch wound treatment. This was created by using N-acryloyl glycinamide (NAGA) and 1-vinyl-1,2,4-triazole (VTZ) mixed as the inverse opal scaffold, temperature responsive poly(N-isopropylacrylamide) (PNIPAM) loaded with vascular endothelial cell growth factor (VEGF) filler. Supramolecular renders superior mechanical properties, in which NAGA VTZ also provide self-healing antibacterial respectively. Besides, existence PNIPAM, endowed thermal-responsiveness property, could release actives response to stimulus. Given these excellent performances, have demonstrated that significantly enhance healing process diabetes rats downregulating expression inflammatory factors, promoting collagen deposition angiogenesis. Attractively, due optical property display color-sensing behavior suitable monitoring management well guidance clinical These distinctive features indicate presented patches huge potential values biomedical fields.

Temperature-induced, rapid changes in the viscosity and reproducible 3-D structure formation makes thermos-sensitive hydrogels an ideal delivery system to act as a cell scaffold or drug reservoir. Moreover, hydrogels’ minimum invasiveness, high biocompatibility, facile elimination from body have gathered lot of attention researchers. This review article attempts present complete picture exhaustive arena, including synthesis, mechanism, biomedical applications thermosensitive hydrogels. A special section on intellectual property marketed products tries shed some light commercial potential
