  • Does polydopamine-polyacrylamide (PDA–Pam) hydrogel adhere to skin?
  • Tissue adhesiveness of the polydopamine–polyacrylamide (PDA–PAM) hydrogel. (a,i) The hydrogel could tightly adhere on the author’s hand and hang a tube full of water with a weight of 63.94 g. (a,ii) Photos of the peeling process of adhesive hydrogel adhered on the author’s skin.
  • Does polydopamine–polyacrylamide hydrogel have good self-healing performance?
  • Biocompatible polydopamine–polyacrylamide (PDA–PAM) hydrogel has good self-healing performance. However, there is a trade-off between the self-healing ability and the mechanical strength. Excellent self-healing often results in the poor mechanical strength, which limits the application in load-bearing field.
  • What is a polydopamine–polyacrylamide hydrogel?
  • Inspired by the natural mussel adhesive mechanism, we designed a polydopamine–polyacrylamide (PDA–PAM) single network hydrogel by preventing the overoxidation of dopamine to maintain enough free catechol groups in the hydrogel.
  • What is a Pam hydrogel?
  • The hydrogel was designed based on a single PAM network that was hybrid-crosslinked with covalent (N, N ’-methylene bisacrylamide (BIS), gray circles) and reversible non-covalent bonds from PDA (black ovals).
