AU engineering researchers develop breakthrough antimicrobial coatings

AUBURN РA team of researchers in Auburn University’s Samuel Ginn College of Engineering has produced new antimicrobial coatings with potential to prevent diseases from spreading on contaminated surfaces Рpossibly solving a growing problem not only in hospitals but also in schools, offices, airplanes and elsewhere.

Led by Virginia Davis, assistant professor in the Department of Chemical Engineering, and Aleksandr Simonian, professor of materials engineering in the Department of Mechanical Engineering, the Auburn researchers mixed solutions of lysozyme, a natural product with antimicrobial properties found in egg whites and human tears, with single-walled carbon nanotubes, or SWNTs, which are strong, microscopic pieces of carbon. SWNTs, at one nanometer in diameter, are a perfect cylinder of carbon and keep the lysozyme intact in the coating.
