Scientists have captured the first high-resolution 3-D images from individual double-helix DNA segments attached to gold nanoparticles, which could aid in the use of DNA segments as building blocks for molecular devices that function as nanoscale drug-delivery systems, markers for biological research, and components for electronic devices.
When scientists Daniel Riley and Jared Schwede left Stanford University last year to join Cyclotron Road, Lawrence Berkeley National Laboratory’s program for entrepreneurial researchers, their vision was to take thermionics, an all-but-forgotten technology, and develop it into a clean, compact, and efficient source of power.
Scientists aspire to build nanostructures that mimic the complexity and function of nature’s proteins, but are made of durable and synthetic materials. These microscopic widgets could be customized into incredibly sensitive chemical detectors or long-lasting catalysts, to name a few possible applications. A discovery by Berkeley Lab scientists is a step in that direction.
