Notre Dame paper examines nanotechnology-related safety and ethics problem
Date:4/27/2012

A recent paper by Kathleen Eggleson, a research scientist in the Center for Nano Science and Technology (NDnano) at the University of Notre Dame, provides an example of a nanotechnology-related safety and ethics problem that is unfolding right now.

The world of nanotechnology, which involves science and engineering down at billionths-of-a-meter scales, might seem remote.

But like most new advances, the application of that technology to everyday experience has implications that can affect people in real ways.

If not anticipated, discussed or planned for, some of those implications might even be harmful.

The problem that Eggleson describes is that hospital-acquired infections are a persistent, costly, and sometimes fatal issue. A patient goes in for one condition, say an injury, but ends up being infected by a microorganism picked up in the hospital itself. That microorganism might even have developed a resistance to conventional drug treatments.

The solution is that engineers are developing new and innovative ways of coating medical materials with nano-sized particles of silver, an element that has long been known for its antimicrobial properties. These particles are being applied to hard surfaces, like bedrails and doorknobs, and to fabrics, such as sheets, gowns, and curtains, by a growing number of medical supply companies. And these new materials are proving effective.

"Nanosilver coatings have made life-saving differences to the properties of typical hospital items," says Eggleson. "Just this last December, a textile made by a Swiss company was the first nano-scale material approved as a pesticide by the EPA."

The possible new danger is that the vast majority of bacteria and other microorganisms are actually neutral, or even beneficial, to human life and a healthy environment. For example, some bacteria are needed to maintain appropriate levels of nitrogen in the air, and others, living inside t
