Chloroplast and Cell Imaging at Submicron Resolution by Two-Photon Excitation

Novel, two-photon NIR excitation fluorescence correlation microspectroscopy tests and preliminary results were presented in this article with submicron resolution for concentrated suspensions of functional cells and chloroplast membranes. Related developments of these technique involve applications of Fluorescence Cross-Correlation Spectroscopy (FCCS) detection to monitoring:DNA- telomerase interactions, DNA hybridization kinetics, ligand-receptor interactions, and HIV-HBV testing.
