Properties of OD‐PP@SeNPs Hydrogel. A) Photographs of the hydrogels adhesion to different substrates. B) Digital images demonstrating the macroscopic adhesion of the hydrogels to various tissues from a rat. C) Softness of OD‐PP@SeNPs hydrogel. D) The self‐healing procedure between two separate OD‐PP@SeNPs hydrogels pieces. OD‐PP@SeNPs hydrogels were stained with Nile red and crystal violet stains. E) Hydrogel injected into various shapes (moldability). F) Injectability of OD‐PP@SeNPs hydrogels and a picture of the crossing needle‐equipped double‐barrel syringe. G,H) Adhesion strength of OD‐PP@SeNPs hydrogels to different substrates (n = 3). Swelling rate of I) OD‐PP hydrogel and J) OD‐PP@SeNPs hydrogel (n = 3). Remaining weight of K) OD‐PP hydrogel and L) OD‐PP@SeNPs hydrogel (n = 3).
