Microscope Slide Enables ~70-nm Resolution

David L. Shenkenberg

Conventional optical microscopes can resolve objects on the order of only 200 nm because they are limited by the diffraction of light waves, meaning that small things such as DNA and viruses cannot be seen. Although both scanning probe and electron microscopes can image biological samples smaller than the diffraction limit, the devices are incompatible with living cells. From metamaterials, researchers made a superlens in the form of a microscope slide. This atomic force microscopy image shows an array of several superlenses. With an ordinary optical microscope, Igor I. Smolyaninov...Read full article
