Enhanced energy transfer in single glycerol/water microdroplets standing on a superhydrophobic surface (original) (raw)

We demonstrate resonant enhancement of energy transfer from donor to acceptor molecules in single glycerol/water microdroplets standing on a superhydrophobic surface. At donor emission wavelengths resonant with a whispering gallery mode, we recorded energy transfer rates up to 10 times higher than the non-radiative (Förster) energy transfer rate, by using the gradual acceptor photobleaching technique.
