Notre Dame study explores the potential benefits and threats of nanotechnology research
Date:1/25/2013

Every day scientists learn more about how the world works at the smallest scales. While this knowledge has the potential to help others, it's possible that the same discoveries can also be used in ways that cause widespread harm.

A new article in the journal Nanomedicine, born out of a Federal Bureau of Investigation workshop held at the University of Notre Dame in September 2012, tackles this complex "dual-use" aspect of nanotechnology research.

"The rapid pace of breakthroughs in nanotechnology, biotechnology, and other fields, holds the promise of great improvements in areas such as medical diagnosis and treatment" says Kathleen Eggleson, a research scientist in Notre Dame's Center for Nano Science and Technology and the author of the study.

"But the risk of misuse of these breakthroughs rises along with the potential benefit. This is the essence of the 'dual-use dilemma.'"

The report examines the potential for nano-sized particles (which are measured in billionths of a meter) to breach the blood-brain barrier, the tightly knit layers of cells that afford the brain the highest level of protectionfrom microorganisms, harmful molecules, etc.in the human body. Some neuroscientists are purposefully engineering nanoparticles that can cross the blood-brain barrier (BBB) so as to deliver medicines in a targeted and controlled way directly to diseased parts of the brain.

At the same time, the report notes, "nanoparticles designed to cross the BBB constitute a serious threatin the context of combat." For example, it is theorized that "aerosol delivery" of some nano-engineered agent in "a crowded indoor space" could cause serious harm to many people at once.

The problem of dual-use research was highlighted last year when controversy erupted over the publication of findings that indicate how, with a handful modifications, the H5N1 influenza virus ("bird flu") can be altered in a way that would enable it to be
