Researchers from the Consejo Superior de Investigaciones Científicas (CSIC) have managed to measure for the first time the resonance frequency of a single bacterium. Using optomechanical devices (which measure light and movement), researchers have observed that bacteria vibrate hundreds of millions of times per second. The resonance frequency of the microorganism provides valuable information about its characteristics, so that it can be identified. This finding, published in the journal Nature Nanotechnology, opens the door for future devices that can detect, universally, on a large scale and with high sensitivity, the presence of any virus or bacteria in a sample.
