Fluorescent nanodiamonds for thermal biology
Abstract
Temperature measurement using fluorescent nanodiamonds is a highly reliable technique because it is largely unaffected by factors such as pH, ion concentration, viscosity, molecular interactions, or organic solvents. Using fluorescent nanodiamonds coated with photothermal polymers as quantum sensors, we measured thermal conductivity inside living cells. We found that intracellular thermal conductivity is about one-sixth that of water, which is much lower than previously assumed. This finding provides new insight into how heat spreads inside cells and has important implications for understanding cellular heat production in biomedical research.
