Researchers at the National Institutes for Quantum Science and Technology (QST), Japan, and The University of Tokyo, Japan, in collaboration with Kyushu University, Japan, have developed a new class of biocompatible molecular quantum nanosensors (MoQNs) that operate inside living cells.

The study demonstrates that these nanosensors enable absolute temperature measurements with subcellular spatial resolution and detect radical-related spin signals in both the cytoplasm and nucleus of living cancer cells. The study was published in the journal Science Advances.
