1. A system comprising (a) a first composition comprising a multi-arm polymer comprising a calix[n]arene core, where n ranges from 4-12 and between 4 and 12 polyoxazoline segments having a first end that is covalently attached to the calix[n]arene core and a second end comprising a moiety that comprises a reactive group and (b) a second composition comprising a multifunctional compound that comprises functional groups that are reactive with the reactive groups of the multi-arm polymer.
