K-9 units from across the U.S. helped secure NATO Summit in Chicago
ATF K-9 teams from Illinois, Kentucky, Michigan, Minnesota, New Jersey, and Texas helped secure the NATO Summit in Chicago this past weekend; on explosives-sniffing dog named Ithaca was also on duty; the dog is famous for his keen sense of smell that enables him to detect approximately 19,000 explosive odor combinations

Detecting biological terror agents
PositiveID Corporation is testing its M-BAND bioagent detection system in preparation for DHS’s $3 billion BioWatch procurement; M-BAND can be remotely set to detect for DNA-based pathogens alone, with or without either RNA-based organisms or toxins, or for all three types of pathogens simultaneously at remotely programmable intervals

New biosensor checks for toxicity in real time
Researchers have married biology and engineering to develop a biosensor – called Dip Chip – that can warn of toxicity in real time; one of the chip’s advantages is its ability to identify toxicity as a biological quality instead of specific toxic chemicals; because the chip measures general toxicity, it will pick up on any and all toxic materials — even those that have not been discovered or invented yet

Using LED technology for UV disinfection
UV light can be used to disinfect, treat drinking-water, sterilize surgical tools, and more; technologies that use aluminum nitride LEDs to create UV light, however, have been severely limited because the substrates which served as the foundation for these semiconductors absorbed wavelengths of UV light which are crucial to applications in sterilization and water treatment technologies; researchers have developed a solution to the problem

Optical sensor specialist to develop explosive sensing technology
Polestar Technologies, a developer of optical sensors, has recently won a $2.5 million government contract from the Joint Improvised Explosive Device Deterrent Organization (JIEDDO) to develop a system for the stand-off detection of explosives hidden on a person

New explosives detection based on micro- and nano-cantilever beam sensors
A team of engineers is investigating micro- and nano-cantilever beam sensors for explosives detection; micro- and nano-cantilever beam sensors offer a distinct advantage in that they are small, very responsive, and very sensitive; their sensitivity and selectivity can also be tuned by modifying the surface treatment
