This Week in Science

In Science this week, researchers from the Braunschweig University of Technology describe the use of a technique of folding DNA at the nanoscale — called DNA origami — to create structures that can be used to visualize biological processes at the single-molecule level. By linking gold nanoparticles to DNA origami structures that incorporate docking sites for a single fluorescent dye, the team created a "nano-lens" that acts as a nanoantenna capable of enhancing the fluorescence.
