Two-photon fluorescence correlation spectroscopy with high count rates and low background using dielectric microspheres
Two-photon excitation fluorescence is a powerful technique commonly used for biological imaging. However, the low absorption cross section of this non-linear process is a critical issue for performing biomolecular spectroscopy at the single molecule level. Enhancing the two-photon fluorescence signa...
