DNA Nanotechnology: Origami and Nanophotonics

This lecture explores the use of DNA origami nanotools for nanophotonics, focusing on light control at the nanoscale. It covers the main elements of nanophotonics, such as optical antennas and metallic nanoparticles, and their interaction with light. The DNA origami technique, introduced by P. Rothemund, is explained, showing how DNA can be used to fabricate nanometer-sized structures. The lecture also discusses challenges in technological breakthroughs, including fabrication and coupling single quantum emitters to optical nano-antennas. Examples of DNA origami functionalization and its advantages, such as self-assembly and design flexibility, are presented.
