Researchers in Australia, Germany and Japan are the first to have used a nanodiamond quantum probe to detect individual atoms in an artificial cell membrane. The technique, which relies on using the quantum properties of the so-called nitrogen-vacancy defects in nanodiamond as magnetic field sensors, could be used to image a wide range of biological phenomena, such as free radicals in situ and even neuron function…….
