Single Particle Studies of Nanocubes Shows Marked Effect of Composition and Substrate

Optical properties of nanomaterials are at the basis of a host
of new technology and prototypes, including sensors, computing devices, and
enhancing substrates for spectroscopy, yet fundamental understanding on how to
tune such properties is just emerging. Researchers at Northwestern University
have previously developed a method to accurately correlate the structure and
properties of nanoparticles at the single particle
level. This technique has now been used in a high throughput fashion to observe
and quantify how the optical response of nanocubes is
affected by size, composition and environment.
