Paper Abstract

A fiber-optical spectrometer for pharmacologically oriented energy metabolism studies using NADH fluorescence has been built up. Starting from theoretical considerations, the system parameters have been optimized. With this optimized geometry, the sensitivity limit for quantitative NADH detection has reached 20 (mu) M. The absolute lower detectable concentration value limited by SNR and other background effects lies below 5 - 10 (mu) M. With cultures of endothelial cells, measurements of the age dependence of NADH fluorescence intensity have been performed. They give a criterion for the metabolic activity of cells selected for further pharmacological investigations.
