Polymers in drug delivery

Curr Opin Chem Biol. 2001 Aug;5(4):447-51. doi: 10.1016/s1367-5931(00)00227-1.


Advances in polymer science have led to the development of several novel drug-delivery systems. A proper consideration of surface and bulk properties can aid in the designing of polymers for various drug-delivery applications. Biodegradable polymers find widespread use in drug delivery as they can be degraded to non-toxic monomers inside the body. Novel supramolecular structures based on polyethylene oxide copolymers and dendrimers are being intensively researched for delivery of genes and macromolecules. Hydrogels that can respond to a variety of physical, chemical and biological stimuli hold enormous potential for design of closed-loop drug-delivery systems. Design and synthesis of novel combinations of polymers will expand the scope of new drug-delivery systems in the future.
