Researchers at Harvard have developed a new method which prevents the formation of bacterial communities on a surface.
A team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface. Biofilms stick to just about everything, from copper pipes to steel ship hulls to glass catheters. The slimy coatings are more than just a nuisance, resulting in decreased energy efficiency, contamination of water and food supplies, and—especially in medical settings—persistent infections. Even cavities in teeth are the unwelcome result of bacterial colonies.
In a study published in the Proceedings of the National Academy of Sciences
), lead coauthors Joanna Aizenberg, Alexander Epstein, and Tak-Sing Wong coated solid surfaces with an immobilized liquid film to trick the bacteria into thinking they had nowhere to attach and grow.
