Multiple scattering-assisted fluorescence amplification: towards biological applications
Abstract
Stimulated amplification of fluorescence signals is obtained under conditions which approach biocompatibility by adding NanoParticles (NPs) to an aqueous solution of fluorescein. The conditions for the stability of the suspension and optimum dye concentration are detailed, together with considerations on photobleaching and phototoxicity. A dedicated experimental setup, coupled to a specified measurement protocol, prove that it is possible to obtain gain factors up to 40, with a considerable reduction in spectral fluorescence linewidth. A pump-energy- and NP-concentration dependence of the fluorescence pulse duration is interpreted as further proof of stimulated amplification. Perspectives and possible biological applications are discussed.
