Scanning probe microscopes produce images based not on light, but on electron density and charge. Scientists are producing incredible images of tinyness heretofore visible only by means of an artist's imagination. Now we have "stereo" images of nanoscopic viruses, cell parts, and even individual atoms. They can also map an electric charge from a nanotube with an electrostatic force microscope.
