Nanoprobe to Identify toxins
Scientists at Oak Ridge National Laboratory (ORNL) have developed a probe to Identify toxins (such as Anthrax) immediately, in real time, as oposed to days (or weeks) of preparing samples and processing the existing way. The paper article has MUCH more technical info than the website article, and it mentions being able to identify almost any substance, even diseased cells within living tissue without having to "prepare" the sample first.
I could really see this as a tool to measure "prove" alergen-free or cross contaminated environments in real-time.
