Nanoparticle Infrared Detector Is Ultrasensitive, Cheap

Canadian researchers have developed an inexpensive and highly sensitive infrared chip that could improve night-vision goggles and medical imaging. Made by spin-coating a glass slide or silicon chip with a solution of conducting nanoparticles called quantum dots, the detector is 10 times more sensitive than traditional infrared detectors. The team that designed the chip is led by Edward Sargent, who holds the Canada research chair in nanotechnology at the University of Toronto.
