"Encoded in the reflected mild will become the identity associated with chemical molecules in the sample," she said.
Prof. Sharon Weiss provides modified white gold leaf paper to ensure that its surface provides signal amplification regarding 100 million times - in order that a new laser and detector to spot caffeine molecules regarding whatever it continues to always be able to be applied to.
"It looks being a thin metal sheet, similar to aluminum foil, as well as if you shine light on it a person are in a new position to see different colors just just like these that will reflect off a new CD once you shine sunlight in it," the girl said.
She mentioned the woman's product is faster.
A Vanderbilt College professor has come up using a faster and significantly less expensive way to test regarding explosives residue on surfaces.
Weiss stated your system will possibly be available commercially inside of a year..
It will even be less costly - costing about $10 for each test as opposed towards the $60 it expenses now.
"Swab the doorway handle or even trunk, along with recognize quickly whether or even Cheap Air Jordan not there is actually certainly explosive residue," she said.
Military or perhaps security officials Cheap Air Jordan 10 Stealth screening regarding explosives from checkpoints or perhaps airports now use significant mass spectrometers or ion mobility spectrometers that need first ionizing a new test before they are usually in the position to identify trace levels of explosives, based on Weiss.
"We commence having a extremely thin, white gold film and also use a simple chemical soak and also one-step direct imprinting procedure to generate what is essentially a fancy gold sponge," said Weiss, an associate professor associated with electrical engineering as well as physics which additionally serves on the Edgewood Chemical Biological Center's research and also Technologies Directorate from Aberdeen, Md.
The foil is actually applied towards the surface becoming tested, then placed inside the portable measurement instrument that will consists of your laser as well as detector which analyzes it
