Single-molecule detection by two-photon excitation of fluorescence
Using a mode-locked titanium: sapphire laser at 700 nm for two-photon excitation we studied fluorescence bursts from individual coumarin 120 molecules in water and triacetin. Fluorescence lifetimes and multichannel scaler traces have been measured simultaneously. Due to the fact that scattered excit...
