Nanostars could bring 3D sensing
Abstract:
Researchers at Rice University, US, have created star-shaped gold nanoparticles that have unusual optical properties. Each arm of the star has a unique spectral signature, giving the materials potential applications in 3D molecular sensing.
"Just a few years ago, everyone's attention was on the size of nanoparticles because altering size was a straightforward way to change the wavelength of light that the particle reacted with," said Jason Hafner of Rice University. "Today, researchers are increasingly interested in intricate shapes and the specific ways that those shapes affect a particle's interaction with light."
