NJIT chemists pave way for cheap, usable field test
Nanoparticles abound now as trace chemicals in polluted air or water. Although they can be identified through current laboratory processes, the task is expensive and time consuming. "We're hoping our research will pave the way to create a lab-on-a-chip that can identify trace pollutants in the field or at home," said Somenth Mitra, PhD, professor of chemistry at New Jersey Institute of Technology (NJIT). Eventually with the aid of such a versatile instrument any worker or homemaker will be able to whip out a cheap, throw-away sensor - just like the ones drug stores now sell for early pregnancy tests - and quickly learn if a toxic chemical is in the air, food or water.
