title: Two-photon fluorescence cross-correlation spectroscopy.
abstract: Dual-color cross-correlation spectroscopy is a special kind of fluctuation analysis which selectively probes the formation or deletion of linkages between two different fluorescently labeled molecules at extremely low concentrations. Two-photon excitation can, under certain circumstances, significantly simplify this method if different probe molecules with distinct emission properties are accessible by a common IR excitation wavelength.
