Researchers develop biocompatible quantum nanosensors for living cells

Japanese researchers created biocompatible molecular quantum nanosensors that work inside living cells.

The sensors enable absolute temperature measurements at subcellular resolution and detect radical-related spin signals in the cytoplasm and nucleus.

Unlike earlier hard quantum sensors, the organic nanocrystal-based devices are more uniform and cell-safe.

The advance could improve studies of cell behavior, oxidative stress, and future medical diagnostics.
