  Nanoga, an EPFL-based startup, has developed a technique to put a nanoscopic watermark onto glass or ceramic. Products with this watermark, which is invisible to the naked eye and only shows up under ultraviolet light, are impossible to counterfeit.

With Nanoga’s new way of combatting counterfeits, each product…

Texas Tech University: Nano-HPLC: Nano Scale Security & Sensors: Advanced Surveillance and Testing

Getting smaller can be a good thing for high performance liquid chromatography (HPLC). Nano-HPLC delivers lab-changing benefits to scientists.

The United States government—nearly 14 years after September 11, 2001—continues to invest heavily in homeland security. In fact, the president’s 2015 budget calls for US$38.2 billion for the Department of Homeland Security, and that equals more than 20…

Engineers in GE labs have built a penny-sized sensor that can detect the faintest traces of explosives and needs no power to operate.

The device uses a special film a tenth the thickness of a human hair to detect chemicals. The team was inspired by their research of the unique iridescence of Morpho butterflies caused by the jagged, forest-like scalesfound on their wings. (They applied data…

VANCOUVER, Feb. 1, 2015 /PRNewswire/ – Lomiko (“Lomiko”) (TSX-V:LMR, OTC:LMRMF, FSE:DH8B) is raising the alarm regarding Canada’s lacklustre efforts to capitalize on new manufacturing and nanotechnology opportunities while concentrating on the oil industry.

“In twenty years the effect of graphene and 3D printing on society will be amazing, very much like the impact of plastics in the sixties and…

Massachusetts Institute of Technology (MIT) chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone.

These inexpensive sensors could be widely deployed, making it easier to monitor public spaces or detect food spoilage in warehouses. Using this system, the researchers have demonstrated that they can…

We are all familiar with the hassles that accompany air travel. We shuffle through long lines, remove our shoes, and carry liquids in regulation-sized tubes. And even after all the effort, we still wonder if these procedures are making us any safer. Now a new type of security detection that uses terahertz radiation is looking to prove its promise. Able to detect explosives, chemical agents, and…
