Earlier efforts to determine the health and environmental effects of the nanoparticles that are finding use in hundreds of consumer products may have produced misleading results by embracing traditional toxicology tests that do not take into account the unique properties of bits of material so small that 100,000 could fit in the period at the end of this sentence.

Researchers at Syracuse University's Department of Biomedical and Chemical Engineering at L.C. Smith College of Engineering and Computer Science are studying the toxicity of commonly used nanoparticles, particles up to one million times smaller than a millimeter that could potentially penetrate and damage cell membranes.

Nanoparticles which float in the air may seem somewhat insignificant. Nevertheless, knowing them is a vital in many fields: for example, when evaluating individual or room filtration systems, the effectiveness of protection equipment for workers who handle potentially dangerous elements and the suitability of the handling practices of nanoparticles in industrial processes.
