Researchers at the Georgia Institute of Technology have developed a paper sensor that can detect explosives.
The device uses carbon nanotubes printed on to paper using standard inkjet technology, and detects trace amounts of explosive materials. Unlike current sensors, the paper based development incorporates a communications device, allowing it to function in most conditions. It also offers a lower cost alternative, reports Nanotechnology Now. The sensor has been designed to detect ammonia in trace amounts - as low as five parts per million, and send an alert to nearby personnel.
The team are hoping the sensors will be taken up by military and humanitarian organisations for use in warzones.
