Addressed Grids for Single-Nanoparticle Studies

ORAL

Abstract

We have developed a grid structure with a simple and robust address system to assist in locating and relocating individual substrate-supported nanoparticles. We demonstrate application of our addressed grids for facile characterization of the SAME nanoparticles in multiple instruments. Our grids can be prepared on a variety of substrates using lift-off photolithography. We will show addressed grids of Cr/Au on silicon, fused silica, and ITO coated glass as well as application to multiple measurements of the same nanoparticles by scanning electron microscopy, optical microscopy, atomic force microscopy, and single nanoparticle spectroscopy.
