Figure 7C: Mixture of Immobilized C. vulgaris cells either treated with DCMU or not, and imaged with fluorescence lifetime contrast and selective plane illumination. 3D axial stack fly-through.
Video of fluorescence lifetime images acquired with 1 um axial spacing and showing immobilized live C. vulgaris cells in a 3D axial stack fly-through. The cells were live and dark acclimed during the imaging. Part of the cells were untreated and part were treated with DCMU to form a mixture of both cell types. The fluorescence lifetime is differs between the cells in the field of view, depending on their exposure to DCMU.
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.
