Abstract
An approach to nanoscale thermometry that utilizes coherent manipulation of the electronic spin associated with nitrogen-vacancy (NV) color centers in diamond is disclosed. The methods and apparatus allow for detection of temperature variations down to milli-Kelvin resolution, at nanometer length scales. This biologically compatible approach to thermometry offers superior temperature sensitivity and reproducibility with a reduced measurement time. The disclosed apparatus can be used to study heat-generating intracellular processes.
