Abstract

The invention provides hydrogel, wherein the hydrogel has a supramolecular cross-linked network obtainable or obtained from the complexation of an aqueous composition including a host, such as cucurbituril, and one or more polymers having suitable guest functionality. One or more polymers in the aqueous composition may have a molecular weight of 50 kDa or more, such as 200 kDa or more. The hydrogel may hold a component, such as a therapeutic compound or a biological molecule. The hydrogels are suitable for use in medicine.
