3D single-molecule superresolution imaging (DH-PALM)

A collaborative effort between the Univ. of Colorado and Stanford Univ. demonstrated three-dimensional superresolution imaging beyond the optical diffraction limit using double-helix photoactivated localization microscopy (DH-PALM). Two molecules as close as 14 nm (x), 26 nm (y), and 21 nm (z) are resolved by this technique. [See PNAS 106, 2995 (2009)]
