Quantum thermometer using nanodiamonds senses a 'fever' in tiny worms C. elegans

Measuring the temperature of objects at a nanometer-scale has been a long challenge, especially in living biological samples, because of the lack of precise and reliable nanothermometers. An international team of researchers has realized a quantum technology to probe temperature on a nanometer-scale, and have observed a 'fever' in tiny nematode worms under pharmacological treatment. This strengthens the connection between quantum sensing and biology and ushers in novel thermal imaging technologies in biomedical research.
