NEW YORK (360Dx) – UK-based University of Hertfordshire and the Defense Science and Technology Laboratory (DSTL) have developed a proof-of-concept digital microfluidic platform that detects four classes of simulated chemical and biological warfare agents on a chip — toxins, vegetative bacteria, bacterial spores, and viruses. Specifically, the system detected the human serum albumin protein toxin, Escherichia coli bacteria, the Bacillus atrophaeus spore, and the MS2 bacteriophage virus.
