Caption
(a) Illustration of the structure of a nanodiamond quantum sensor coated with a pyrogenic polymer, and how it operates as a hybrid nanoheater/thermometer. (b) Electron microscope image of hybrid sensors. (c) Working principle of the hybrid sensor for measuring nanometric thermal conductivity. In a medium with high thermal conductivity, the temperature increase of the diamond sensor is moderate, because heat readily diffuses away. In contrast, in a low thermal conductivity medium, the temperature rise is significantly larger. Intracellular thermal conductivity can be determined by measuring the temperature change of the hybrid sensors in cells.
