Design of Zwitterionic Polymer Hydrogels for Biomedical Applications

Abstract

Zwitterionic polymers are ionic polymers containing both positively and negatively charged groups in one monomer unit. These polymers exhibit excellent biocompatibility derived from high polarity and hydrophilicity. Recently, zwitterionic polymer hydrogels have attracted attention not only for applying bioinert biocompatibility for wound healing but also for biosensors and other applications combined with multifunctionality of high mechanical strength, self-healing properties, high ionic conductivity, etc. In this review, we describe recent research in the design of zwitterionic polymer hydrogels for biomedical applications.
