The invention provides a "host-guest" supramolecular hydrogel. The hydrogel contains an AAm/NVP interpenetrating polymer network (IPN) with supramolecular cross-linkers assembled from β lactam/adamantane-containing guest molecule with host polymeric cyclodextrin (PCD). An advantage of this hydrogel is that because of the molecular association of polymeric cyclodextrin and adamantane, the supramolecular hydrogels self-heal without any external stimuli after the hydrogels are severed. The invention also provides methods of making the hydrogel, methods of making the synthesis intermediates, and methods of diagnosis or treatment of β-lactamase-containing bacteria.
