A new silicon chip that harnesses emerging technology at the nano scale will allow the detection of viruses faster, and more accurately, than ever before. One of the applications of this new technique will help save thousands of lives in patients undergoing heart transplants; by enabling doctors to detect rapidly whether a donor heart is infected or not. The scientists announced their discovery today in the Institute of Physics journal Nanotechnology.
The device, called the “ViriChip” was developed by a team led by Dr Saju Nettikadan from BioForce Nanosciences, in collaboration with Des Moines University, both in the USA.
The ViriChip is a small silicon chip about a quarter of an inch across (6mm) which has tiny droplets of antibodies printed on the surface. A single ViriChip can be printed with hundreds of different antibodies. These antibodies act as landing pads for viruses, which attach themselves selectively to certain antibodies. Once the viruses have landed on a particular droplet, they can be detected using an atomic force microscope (AFM). The AFM is a small and simple machine that uses a tiny “finger” to feel bumps on the surface of the chip at the nanometer scale. The AFM method is fast, very sensitive (it can “see” individual viruses) and it does not destroy the viruses so they can be further analyzed e.g. by cell culture and other methods.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
