Researchers creating polymers that act like biomolecules

Published in Drug Week, April 23rd, 2004

A group of bio-inspired polymers are being studied by researchers at the U.S. Department of Energy's Ames Laboratory to understand how they are able to form and react to stimuli similar to the way proteins, lipids and DNA react in nature.

Unlocking how these soluble block polymers are able to self-assemble could potentially lead to a variety of uses such as controlled-release systems for sustained and modulated delivery of drugs or gene therapies.

Ames Laboratory materials chemist Surya Mallapragada and her research team are focusing on pentablock polymers - polymers that form in strings of five chains. Each string comprises two cationic (positively...
