Silver Nanoparticles ‘Valuable’ for DNA Self Assembly

Description University of Arizona researchers have introduced a new method to deterministically and precisely position silver nanoparticles onto self-assembling DNA scaffolds. Now Hao Yan and Yan Liu, professors at the Biodesign Institute's Center for Single Molecule Biophysics and their collaborators used a long single-strand of DNA, which had been folded into a triangular building platform through a process known as DNA origami. This foundation 'decorated' with silver nanoparticles self-assembled at pre-determined locations on the DNA nanostructure. The work demonstrated for the first time the viability of using silver, rather than the gold nanoparticles for DNA-tile or origami based architectures.
