(A) Schematic representation of the excellent performance of the NNH patches and their application to diabetic wounds. (i) Images of NNH patches against S. aureus and E. coli from scanning electron microscope (SEM). (ii) In vivo diabetic wound healing. The size and quantification of the wound closure area from the PBS group, VEGF group, NNH patch group, CSD group and NNH-VEGF patch group. (iii) Scheme of the compression of NNH bulk. Representative of compression and retraction of NNH bulk. (iv) Scheme of the temperature-responsive feature of the NNH patches. Reflection images and spectra of NNH patches at a temperature of 37 ​°C (Reproduced with permission of Ref. [123]). (B) Scheme of the antioxidant thermoresponsive hydrogel. (v) Quantification of the functional blood vessel density (Reproduced with permission of Ref. [127]).
