TLDR
A new strong, biocompatible and biodegradable double-sided tape can adhere to wet tissues and devices through a mechanism involving rapid water removal from the surface, swift hydrogen and electrostatic interactions, and covalent bonding.Abstract:
Dry adhesive materials, particularly in the form of a film or tape, for adhering one or more wet surfaces comprising: (i) one or more hydrophilic polymers; (ii) one or more amine coupling groups, and (iii) one or more cross linkers. The dry adhesive material, when placed in contact with the one or more wet surfaces, absorbs liquid from the one or more wet surfaces, swells to form temporary crosslinking with the wet surface, and forms covalent crosslinking with the one or more wet surfaces.read more

Mussel-Inspired Adhesives and Coatings
TL;DR: Mussels attach to solid surfaces in the sea and their adhesion must be rapid, strong, and tough, or else they will be dislodged and dashed to pieces by the next incoming wave.
