Superesolution Technique (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption The graph on left shows that with the active feedback system off there is a resolution drift of about 0.3 pixels or 19 nanometers, but with the feedback system on resolution is maintained at better than 0.01 pixels, or about 0.64 nanometers. The image on right shows individual Cyanine (Cy) fluorescent dye molecules -- Cy3 and Cy5 -- used to label 20 base pairs of double-stranded DNA.
