Cornell Researchers Develop Faster Metabolic Imaging Method

Cornell University researchers have created two-photon fluorescence polarization ratiometric microscopy (FPRM) to track cell metabolism in real time. Published in Science Advances, this method allows for faster screening of therapeutic treatments by measuring how NADH molecules rotate within cells to indicate energy generation.

Unlike traditional fluorescence lifetime imaging, which requires prolonged light exposure that stresses cells, FPRM uses polarized light to observe dynamic metabolic processes over short periods. The technique provides a more efficient way to monitor cell activity without the damage associated with standard imaging methods.
