21 June 2004 Fluorescence lifetime imaging with a multifocal two-photon microscope

Two photon microscopy is a powerful tool for cells or tissues imaging. However it presents the drawback of being a laser-scanning technique leading to long acquisition time for fluorescence lifetime imaging. Thus it is commonly limited to intensity images that only give indications on location of fluorophores but hardly reports physico-chemical properties and interactions between cells components. To preserve biological samples from too long experiments and provide a more complete spectroscopic tool we developed a time-resolved multifocal multiphoton microscope. This setup allows us to speed up the acquisition while keeping the possibility to measure both intensity and lifetime images for all multifocal points.
