The trillions of tiny molecular nanomachines that are at work inside our bodies and are keeping us alive perform such tasks as building and breaking down molecules, moving materials around a cell, and processing and expressing genetic information – and they do this while consuming remarkably little energy.

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.
