Nanotube-Based Sensor Detects Gama Rays
Detecting dangerous gamma rays could become simpler and less expensive, thanks to a new sensor based on a carbon nanotube-polymer composite (Angew. Chem. Int. Ed., DOI: 10.1002/anie.200904936). The technology, which relies on a simple resistivity measurement, could find practical use in national security or nuclear research, say MIT’s Timothy M. Swager and Jose M. Lobez, who created the device. The sensor is composed of a network of multiwalled carbon nanotubes embedded in a . . .
