University of Massachusetts Amherst chemical engineer Sarah L. Perry, working with a colleague at the University of Illinois, is creating new bioinspired materials using electrostatic charges to direct the self-assembly process of long molecules. The research team, working with a class of polymers called coacervates, found they could be modified by changing the sequence of charges along the polymer chain. Coacervates are commonly used in food products and cosmetics. The findings are published in the journal Nature Communications.
Perry and Charles Sing, professor of chemical and biomolecular engineering at the University of Illinois at Urbana-Champaign, collaborated on the research. They say that long chain molecules called polymers are ubiquitous in biology where the precise sequence of chemical building blocks in the chain, known as monomers, encodes the structure and function of life. Perry and Sing are looking for ways to use this kind of chemical patterning to design new synthetic materials.
