Various chemicals used for photodynamic therapy, a promising treatment for cancer, exhibit high fluorescence yields, which can be used for tumour detection. For a chosen few such compounds fluorescence lifetimes, absorption, and steady state fluorescence spectra were measured at different concentrations (ranging from 10(-5) M to 10(-8) M) in a variety of solvents. The lifetimes were repeated at three different concentrations (ranging from 10-5 M to 10(-6) M) in suspensions of 3T3 fibroblast cells.
