Abstract
fluorescent signals and local temperature variations in living bodies, thus providing the most direct means for the in-depth understanding of biological processes in cells. Herein, we systematically categorize the currently reported fluorescence thermometers based on the aspects of fluorescence intensity and wavelength, reveal the intrinsic relationship between fluorescence (intensity and wavelength) and temperature response, expound the applications of fluorescence thermometers in the fields of chemical sensing and biomedicine, and analyze the challenges faced by current fluorescence thermometers based on fundamental problems and practical applications simultaneously, thus highlighting the future directions of fluorescence thermometers.
