Abstract
We describe a new technique, standing wave axial nanometry (SWAN), to image the axial location of a single nanoscale fluorescent object with sub-nanometer accuracy and 3.7 nm precision. A standing wave, generated by positing an atomic force microscope tip over a focused laser beam, is used to excite fluorescence; axial position is determined from the phase of the mission intensity.
