This anti-biofilm acts as an anti-adhesive and is another approach to dealing with unwanted bacteria on medical implants and on marine equipment. From an April 25, 2016 news item about the Israeli research on ScienceDaily,
Researchers at Ben-Gurion University of the Negev (BGU) have developed an innovative anti-biofilm coating, which has significant anti-adhesive potential for a variety of medical and industrial applications.
According to the research published in Advanced Materials Interfaces, anti-adhesive patches that are developed from naturally occurring biomaterials can prevent destructive bacterial biofilm from forming on metal surfaces when they are immersed in water and other damp environments.
An April 25, 2016 American Associates Ben Gurion University of the Negev news release (also on EurekAlert), which originated the news item, describes the research further without adding much detail (Note: A link has been removed),
“Our solution addresses a pervasive need to design environmentally friendly materials to impede dangerous surface bacteria growth,” the BGU researchers from the Avram and Stella Goldstein-Goren Department of Biotechnology Engineering explain. “This holds tremendous potential for averting biofilm formed by surface-anchored bacteria and could have a tremendous impact.”
The anti-adhesive could be used on medical implants, devices and surgical equipment where bacteria can contribute to chronic diseases, resist antibiotic treatment and thereby compromise the body’s defense system. The prevention of aquatic biofouling on ships and bridges is one of the industrial applications.
