[Nano-Medecine] – Wearable medical sensors to get major sensitivity boost 22 février 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.

[Perovskites] -Perovskites reveal huge resettable single-photon response 23 février 2020

Despite the progress in perovskite device efficiencies, these systems are not fully understood, in particular the frequency- and power-dependence of their response to light. Yu-Hwa Lo and colleagues at the University of California in San Diego (UCSD) now report on systematic investigations of how these devices respond to light for frequencies varying over eight orders of magnitude and power ranging from millions to single photons.
