Glow Sticks: From Parties to Detecting Biothreats for the Navy
Remember that party where you were swinging glow sticks above your head or wearing them as necklaces? Fun times, right? Science times, too. Turns out those fun party favors are now being used by a University of Houston researcher to identify emerging biothreats for the United States...
Briefs: Test & Measurement
Any space, enclosed or open, can be vulnerable to the dispersal of harmful airborne biological agents. Silent and near-invisible, these bioagents can sicken or kill living things before steps...

Micro UV Aerosol Detector
The detection of aerosols within fluid samples can be accomplished by optical methods. Such methods are useful in detecting potentially harmful aerosols such as biological aerosols that may be present after a biological agent attack or industrial accident. It is well known that biological molecules fluoresce when excited...
