Handheld terahertz scanners could soon be sniffing for drugs and explosives, transmitting super-high-speed data, and looking inside your body, based on a new nanoscale T-ray device developed by researchers in the UK and Singapore. The new device can produce a much stronger beam of terahertz radiation than was previously thought possible, and at room temperature to boot.
Devices using terahertz radiation could lead to applications in security screening, chemical sensing and more

Terahertz radiation, or T-rays, can see through clothing, paper, cardboard and numerous other materials, so scientists have been touting their potential for years. A T-ray-based imager could spot concealed weapons hidden under a person's clothes or even identify tumors without inducing any bad side effects.
