A researcher at Notre Dame University’s Center for Nano Science and Technology (NDnano), United States, has written a paper that provides an example of a nanotechnology-related safety and ethics problem that is currently unfolding. Kathleen Eggleson, a research scientist at the Center, said the world of nanotechnology may seem remote to many people, but, like most new advances, the application of the technology to everyday life has implications that can affect people in real ways, some of which might even be harmful. Eggleson describes how nanosilver is being developed for use in medical facilities, to coat medical materials, as well as applying the nanoparticles to hard surfaces and fabrics, to help reduce the number of hospital-acquired infections. These new materials are proving effective, but, says Eggleson, the vast majority of bacteria and other microorganisms are actually neutral, or even beneficial, to human life and a healthy environment. Overuse of nanosilver products could pose a danger to such microorganisms and enable resistant strains to flourish. “Under most conditions, the preservation of microbial biodiversity is a benefit,” explains Eggleson. “In fact, those who would use these potent new antimicrobial technologies for frivolous uses, such as for odor control, work directly against the U.S. National Nanotechnology Initiative’s goal of responsible nanotechnology development.”
