ABSTRACT
During the last few years, the technical and scientific significance of functional polymers has been well recognized; at present, a lot of concentration has been focused on bio-responsive polymers. In the field of bio-responsive polymer synthesis, free radical polymerization has added a lot of attention attributable to its effortlessness, compatibility, and expediency. The polymer containing a bio-responsive system can either participate in a chemical reaction or result in cleavage of a chemical bond. Briefly, a bio-responsive polymer undergoes an abrupt change in its physical properties in response to a small biological stimulus. A bio-responsive polymer undergoes transduction all the way through the networks of an extremely hydrophilic monomer including species like ethers, thiols or hydroxyls along with ionizable groups for example amines and carboxyls. This chapter discusses more specific mechanism for various bio-responsive polymers like glucose-responsive, enzyme responsive, inflammation responsive, antigen responsive, DNA responsive, redox-responsive, and pH-responsive polymers.
