"Cells of Escherichia coli labeled with an amino-specific Alexa Fluor dye, de-energized by exposure to light, and examined in a fluorescence microscope. By using pulsed light (strobed laser illumination at a smaller average intensity) and an ordinary CCD camera, one can see what flagella do as swimming cells run and tumble.
