Shapiro, H. M. 2004. The most popular methods of single-molecule detection are based on fixed-wavelength excitation of individual molecules combined with dispersed detection of emission. Avoid overlap of emission spectra. Common filter blocks are named after the type of excitation filter: UV or U (Ultraviolet excitation for dyes such as DAPI and Hoechst 33342), B (Blue excitation for FITC and related dyes), and G (Green excitation for TRITC, Texas Red®, etc. First, PRENTs were developed through a modular design utilizing gold-nanoparticle-Raman reporter complexes protected and functionalized by polyethylene glycol derivatives. Therefore, APC-Vio 770 is an ideal tandem conjugate for this channel in all flow cytometers. In order to determine the emission spectrum of a particular fluorochrome, the wavelength of maximum absorption (usually the same as the excitation maximum) is determined and the fluorochrome is excited at that wavelength. Excitation and emission spectra of 1.0X PicoGreen free dye (light red) and in the presence of 50 ng/µL salmon dsDNA (dark red). Next, PRENTs were efficiently optimized for excitation with near-infrared light through inclusion of near-infrared chromophores as Raman reporters and exploitation of the size-dependent optical enhancement of gold nanoparticles. Accordingly, flow cytometry has become an invaluable tool for parsing immune cell populations because this technique permits the simultaneous detection of up to 18 markers on a single cell. Two-photon excitation allows accession of common fluorophores of largely distinct emission by the same excitation wavelength, because differences in selection rules and vibronic coupling can induce considerable shifts between the one-photon and two-photon excitation spectra.
