“There are several different technologies or approaches to prevention of bacterial growth, killing bacteria, says Hizal. This further enables the bacteria to be washed off more easily with flow, minimizing bacterial infection problems and food poisoning. They also treated the surface with Teflon hydrophobic material to further discourage bacterial adhesion and growth due to the entrapped air pockets between the pillars. They discovered that compared to planar surfaces, a surface of nanopillars, or sharp-tipped needle-like structures (smaller than bacteria), inhibits the adhesion of the bacteria. Choi at Stevens Institute of Technology in collaboration with the University of Hawai’i, Manoa, have found a unique solution to drastically reduce bacterial adhesion on metal surfaces. aureus adhere to the surface of these metals, they can lead to damage to the heart and kidneys, cause food-borne illness and a host of other serious problems. Chang-Hwan Choi) in the Department of Mechanical Engineering, won the Best Student Paper award for his paper titled “Nano-Engineered Alumina Surfaces for Prevention of Bacteria Adhesions.”īacterial adhesion poses a problem to the metals we encounter everywhere: Pipes, water-distribution systems, filtration processes, cooling facilities, ship hulls, aquaculture systems, food processing systems and bio-implants such as hips and knees.
