| Research Abstract |
Comprehensive studies have been carried out concerning on instrumental and data-processing methods for fluorescence lifetime measurements with a purpose of enhancing capabilities of discriminating tumor cells from normal cells. Our final goal is developing diagnostic metrology. In a series of studies, we have developed a phase-modulation fluorometer using a phase-modulated light source, a photon-counting-type phase-modulation fluorometer, and a near-infrared fluorometer using a radio-frequency lock-in amplifier. By using these systems, we have measured a fluorescence lifetime of the indocyanine green solution and that of 6 1×10^<-6> M coumarin 152 in ethanol with precision.
