Studying the Applications and Characterisation of Gold Nanoparticles by Nanoparticle Tracking Analysis

Malvern Panalytical

Gold nanoparticles are one of the most popular and extensively researched types of nanoparticle; a Google Scholar search of the term results in over 500,000 hits.

Applications range from the biological to the material, and include nanomedicine, drug delivery, cancer diagnostics, biological scaffolds, biosensors, contrast agents, catalysts, and CMP slurries for the manufacturing of microprocessors.

This wide ranging application space is made possible by their versatile optical properties, compatibility with a variety of surface chemistries, and their well-studied synthesis and preparation.

Our Nanoparticle Tracking Analysis (NTA) technology utilizes the properties of both light scattering and Brownian motion in order to obtain the particle size distribution of samples in liquid suspension. Here we present examples of different types of gold nanoparticle samples characterized by NTA.
