The founding father of DNA nanotechnology – a field that forges tiny geometric building blocks from DNA strands – recently came to SLAC to get a new view of these creations using powerful X-ray laser pulses.
For decades, Nadrian C. "Ned" Seeman, a chemistry professor at New York University, has studied ways to assemble DNA strands into geometric shapes and 3-D crystals with applications in biology, biocomputing and nanorobotics.
Since 2009, SLAC scientist John Bargar has led a team using synchrotron-based X-ray techniques to study bacteria that help clean uranium from groundwater in a process called bioremediation. Their initial goal was to discover how the bacteria do it and determine the best way to help, but during the course of their research the team made an even more important discovery: Nature thinks bigger than that.
Daniel DePonte, a pioneer in finding ways to serve up a steady and precise supply of crystals, viruses and other precious samples for laser experiments, is the newly hired sample-delivery group leader for SLAC’s Linac Coherent Light Source X-ray laser.
