Extended Data Fig. 1: The overall process of DST application.
From: Dry double-sided tape for adhesion of wet tissues and devices
The DST can be applied directly onto wet tissue surfaces after removing the backing, without any other preparation process. Upon contact with the wet surfaces, the DST dries them by quickly swelling and absorbing the interfacial water. Simultaneously, the carboxylic acid groups in the DST form temporary crosslinks through intermolecular bonds with the tissue surfaces, followed by covalent crosslinking between NHS ester groups in the DST and primary amine groups on the tissues. After adhering on tissues, the swollen DST becomes a thin layer of tough hydrogel which provides robust adhesion between the surfaces. Dissipation indicates the mechanical energy dissipation from the DST during deformation by the applied force, F.
