Figure 7B: Immobilized C. vulgaris cells, treated treated with DCMU, and imaged with fluorescence lifetime contrast and selective plane illumination. 3D projection rotating around the Y axis.
Video of fluorescence lifetime images acquired with 1 um axial spacing and showing immobilized C. vulgaris cells treated with DCMU in a rotating projection around the Y axis. The cells were live and dark acclimed during the imaging. The fluorescence lifetime of those cells is increased due DCMU blocking electron acceptor oxidation and thus reaction center quenching.
Fluorescence lifetime microscopy with QuantiCam SPAD array sensor. 60x 1.49 NA oil objective, and Mizar Tilt selective plane illumination module. Cells were immobilized in low melting temperature agarose.
