    Analyses of emission spectra of biological fluorophores

  • Original language description

    Fluorophores are chemical compounds that can re-emit light upon light excitation. In our organism, we can find many types of bio-fluorophores. The most interestingis NADH that plays an important role in the respiratory chain embedded in the mitochondria. Much pathology included cancer and others diseases in human body is related to dysfunction of mitochondria and variation of ATP production.Our motivation is to use NADH as a biomarker for cell’s viability. By preparing NADH in media of various pH,we would determine the differences in their fluorescence emission spectra recorded using three excitation wavelengths –340nm, 350 and 365nm. The fluorescence spectrum of the mixture of NADH with other two bio-fluorophores (pyridoxine and tryptophan) was analyzed by deconvoluting SW GASPED, to recognize the contribution of NADH in this spectrum. The all measurementswere performed on a Shimadzu UV-3600 spectrophotometer and a Fluoromax-4 fluorimeter. The important parameter of fluorescence, quantum yield, was also calculated. The experiment and the analyses of fluorescence spectra were also applied to the yeast.
