nano-optics

Want to make a virus? It’s easy: combine one molecule of genomic nucleic acid, either DNA or RNA, and a handful of proteins, shake, and in a fraction of a second you’ll have a fully-formed virus. That might sound like the worst infomercial ever, but in many cases making a virus really is that simple… Read more

Researchers from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a gold nanocylinder equipped with discrete DNA strands as ‘feet’ that can walk across a DNA origami platform. They are able to trace the movements of the nanowalker, which is smaller than the optical resolution limit, by exciting plasmons in the gold… Read more
