Salt metathesis for developing injectable supramolecular metallohydrogelators as a multi-drug-self-delivery system.

Salt metathesis has been exploited to generate a series of nonsteroidal anti-inflammatory drug (NSAID) based Zn(II) metallo-hydrogels displaying both anti-inflammatory and anti-bacterial properties. Relatively low cytotoxicity, rheoreversibility and injectibility of one of these hydrogels make it suitable for multi-drug-self-delivery application.
