Research Abstract

We have constructed a femtosecond time-resolved fluorescence system using up-conversion techniques for the purpose of obtaining fluorescence lifetime images with an inverted microscope. From the analysis of fluorescence decay profiles of autofluorescent species such as FAD and NADH and fluorescent proteins in the femtosecond to nanosecond time range, we have proposed that the measurement of the fluorescence lifetime can be used for noninvasive determination of the status of individual cells such as intracellular pH and polar environments. Effect of metal surface on the fluorescence lifetime of dye molecules has also been discussed.
