Click Chemistry-based Injectable Smart Hydrogels

Abstract

Injectable hydrogels generated by click chemistry-based covalent bonding have been investigated as potential smart biomaterials for application in medical devices, drug delivery systems (DDS), regenerative medicine, and tissue engineering. In this chapter, we introduce traditional click chemistry-based injectable smart hydrogels prepared with chemical cross-linking of biocompatible polymers. Additionally, we show our cell cross-linked hydrogels in which living cells are covalently cross-linked with polymer gel networks as new generation click chemistry-based injectable gels.
