Selenium-containing Polymers:

Redox responsive polymers have attracted wide interest for their promising applications in controllable encapsulation and delivery in physiological environments, where the redox process is constantly and widely present. A series of selenium-containing polymers, including main chain and side chain block copolymers, dendrimers and hyperbranched polymers, have been designed and synthesized for controlled self-assembly and disassembly under various responsive stimuli, which may act as new biomaterials for controlled drug delivery and enzyme mimics.
