FITC (Fluorescein isothiocyanate) is fluorescent material that has high fluorescence quantum yield. But generally, when fluorescent materials are in a solution, they can lose their excitation by nonradiative means : through collisions with other atoms or molecules. It is called dynamic quenching. Thus if FITC is encapsulated into SWNTs (single-walled carbon nanotubes), losing their excitation by nonradiative means may decrease.In this way, we expect to increase fluorescence lifetime of FITC. We inserted FITC into the inside SWNTs. And to confirm that FITC was encapsulated into SWNTs, We used simultaneously AFM(Atomic Force Microscope) and PL (Photoluminescence). Afterward we measured lifetime of FITC using TRS (Time-resolved fluorescence spectroscopy).
