Self‐Assembled Silver Nanoparticles in a Bow‐Tie Antenna Configuration

Abstract

The self-assembly of silver nanoparticles into a bow-tie antenna configuration is achieved with the DNA origami method. Instead of complicated particle geometries, spherical silver nanoparticles are used. Formation of the structures in high yields is verified with transmission electron microscopy and agarose gel electrophoresis. According to finite-difference time-domain simulations, the antenna configuration could be used as a DNA sensor.
