Abstract

One of the cornerstones in nanophotonics research is the miniaturization of optical devices to the nanometer scale. DNA nanotechnology offers a pathway to realize high-speed nanoscale optical devices using DNA as a molecular building block. Its biorecognition and addressability have led to the successful engineering of self-assembled nanostructures. In particular, the DNA origami technique, which involves the bottom-up self-assembly of long single-stranded DNA “scaffold” into predefined 2D and 3D shapes using specifically designed short oligonucleotides “staple strands”, enables the scalable production of intricate nanostructures with high yields. In this talk, I present recent advancements and my perspectives on self-assembled plasmonic nanosystems using DNA origami technology. These systems include plasmonic waveguides, optical nanoantennas, and plasmonic switches, which efficiently manipulate, concentrate, and guide light without being diffraction-limited. Advanced near/far-field optical spectroscopies empower precise characterization of these plasmonic systems with nanometer resolution. The optical spectroscopy results reveal that DNA-assembled plasmonic devices allow sub-micron mode confinement and well-defined surface plasmon resonances within a specific frequency window. These capabilities hold significant potential in nanoscale energy transfer, energy conversion, biosensing, and various biomedical applications.
