3D Single Molecule Imaging

A team of researchers led by professor Rafael Piestun of the department of electrical and computer engineering at the University of Colorado and William E. Moerner, professor of chemistry at Stanford University, have demonstrated for the first time a method for three-dimensional optical imaging of objects smaller than 20 nanometers over a wide spatial range. Optical imaging at these scales is of great interest in biomedical sciences and nanotechnology. The new findings, which provide a powerful tool for the super resolution of single molecules, have implications for characterizing defects in materials, the characterization of nanostructures, and the three-dimensional, biophysical and biomedical imaging of tagged molecules inside and outside of cells.
