Single Molecule Pulsed Interleaved Excitation Fluorescence Resonance Energy Transfer (PIE-FRET) inside Nanometer-scale Apertures at Biologically Relevant Concentration

Not Accessible

Your library or personal account may give you access

Abstract

PIE-FRET offers significant advantages over conventional single molecule FRET techniques, but it still requires the dilution of samples to biologically low concentrations. Here, we present FRET measurements inside nm-sized apertures at ~1000 times higher concentration.
