Time-resolved UV fluorescence spectroscopy of aorta using 320 nm excitation

摘要

Fluorescence decay of aorta and its fluorophores has been studied at 380, 440, and 480 nm using 320 nm picosecond dye laser excitation and time-correlated single photon counting technique. Fluorescence decay was found to be nonexponential at all emission frequencies. Fluorescence decay at 380 nm shows biggest differences between normal and plaque tissues.
