[Nano-Medecine] – Wearable medical sensors to get major sensitivity boost 22 February 2020

Biosensors integrated into smartphones, smart watches, and other gadgets are about to become a reality. In a paper featured on the cover of the January issue of Sensors (“Vertically Coupled Plasmonic Racetrack Ring Resonator for Biosensor Applications”), researchers from the Moscow Institute of Physics and Technology describe a way to increase the sensitivity of biological detectors to the point where they can be used in mobile and wearable devices. The study was supported by the Russian Science Foundation.

[Nano-Medecine] – X-ray microscopy shows that nanoparticles can change cells 22 February 2020

Today, nanoparticles are not only in cosmetic products, but everywhere, in the air, in water, in the soil and in food. Because they are so tiny, they easily enter into the cells in our body. This is also of interest for medical applications: Nanoparticles coated with active ingredients could be specifically introduced into cells, for example to destroy cancer cells.

[Optoelectronic] – Creating custom light using 2D materials 21 February 2020

Finding new semi-conductor materials that emit light is essential for developing a wide range of electronic devices. But making artificial structures that emit light tailored to our specific needs is an even more attractive proposition. However, light emission in a semi-conductor only occurs when certain conditions are met.
