Researchers at Purdue University have developed a miniature device sensitive enough to detect a single virus particle, an advancement that could have many applications, including environmental-health monitoring and homeland security.
This photo, taken with a scanning electron microscope, shows a miniature "cantilever," a diving board-like beam of silicon that researchers at Purdue University have used to detect a single virus particle weighing about one-trillionth as much as a grain of rice. The work, funded by the National Institutes of Health, is aimed at developing advanced sensors capable of detecting airborne viruses, bacteria and other contaminants. Such sensors will have applications in areas including environmental health monitoring in hospitals and homeland security. (School of Electrical and Computer Engineering, Purdue University)
The device is a tiny "cantilever," a diving board-like beam of silicon that naturally vibrates at a specific frequency. When a virus particle weighing about one-trillionth as much as a grain of rice lands on the cantilever, it vibrates at a different frequency, which was measured by the Purdue researchers.
"Because this cantilever is very small, it is extremely sensitive to added mass, such as the addition of even a single virus particle," said Rashid Bashir, an associate professor of electrical and computer engineering and biomedical engineering.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
