Single Nanoparticle Spectroscopy: An Analysis of Sample Preparation and Microscopy TechniquesPublic Deposited
This paper explores the various approaches to time-resolved single nanoparticle spectroscopy. Due to the novelty of these types of experiments, several difficulties arise in creating a feasible physical setup capable of imaging single nanoparticles less than 100 nm in size. The various difficulties in setup and their attempted resolutions will be discussed, placing particular emphasis on gold and silver nanoparticle synthesis, sample preparation, and details of spectroscopic setup and methods. It will be shown that total internal reflection microscopy in conjunction with careful sample preparation is a promising step toward investigating the material properties of single nanoparticles.
