Scientists use X-rays to peer into a person's body, and a new X-ray imaging technique does the same for individual cells. “You should be able to image most macromolecular assemblies inside the cell”, such as proteins and DNA, says Pierre Thibault, a physicist at the Paul Scherrer Institute in Villigen, Switzerland who leads the team that reports the new technique in the July 18 Science.Also, “it’s certainly a very important tool for nanotechnology,” Thibault says. The best light microscopes can’t distinguish features smaller than 200 nanometers. But images made with the new te...Published: Thursday, July 17th, 2008Found in: Body & Brain and Genes & Cells -
