Engineers develop new sensor to detect tiny individual nanoparticles

(Washington University in St. Louis) A team of researchers at Washington University in St. Louis, led by Lan Yang, Ph.D., the Das Family Career Development Associate Professor in Electrical & Systems Engineering, and their collaborators at Tsinghua University in China have developed a new sensor that can detect and count nanoparticles, at sizes as small as 10 nanometers, one at a time. The researchers say the sensor could potentially detect much smaller particles, viruses and small molecules.
