Polymer Swab Detects Explosive Residue
Purdue University researchers have developed a new device, Nanobrush, a highly pliant, deformable material that is thermally stable from 200 to 250 degrees Celsius and is inexpensive to produce. It does not leave a residue on surfaces it contacts, and it can dislodge and capture explosive residue from cavities that may be as small as 10 microns wide by 10 microns deep. The functionality of the Nanobrush can be improved by attaching functional groups to the tips of the fibers. This technology will substantially improve the ability to detect trace amounts of explosive materials, biological warfare agents, and other substances of interest to the Department of Homeland Security.
