Nanoscale thermometry has untold possible uses for biology, from basic research on how heat flows in living systems to controlling gene expression with temperature. Researchers use a number of techniques for biological thermal sensing, including Raman spectroscopy and detection of fluorescing proteins. But all have problems, such as low sensitivity or the inability to make highly localized measurements.
