—Fluorescence properties of 9‐aminoacridine in aqueous solutions of 7‐methylguanosine (7MeG) and 1, N 6 ‐ethenoadenosine monophosphate (εAMP) have been examined. It was found that fluorescence of the dye was quenched by 7MeG and εAMP as well as by unmodified nucleotides such as GMP and AMP. Quantitative analysis of the results shows that both dynamic and static quenching processes are responsible for the quenching of fluorescence.
