Imaging technique for unique views of single molecules that conventional methods can`t match
(PHYSorg.com Nanotechnology)

Determining the exact configuration of proteins and other complex biological molecules is an important step toward understanding their functions, including how they bind with receptors in the body. But such imaging is difficult to do. It usually requires the molecules to be crystallized first so that X-ray diffraction techniques can be applied-and not all such molecules can be crystallized.
