Health care professionals use tiny particles of gold (nanoparticles) for a variety of medical applications—from diagnostic imaging to cancer treatment. Gold works well for these applications because ...

To remove micropollutants such as pesticides and trace chemicals from the environment, you need something equally small and cunning. One potential method is photocatalysis, which uses semiconducting ...

Chiral gold nanostars show how molecular asymmetry transfers to high-symmetry nanoparticles, producing structures with distinctive optical behavior and enhanced molecular detection. (Nanowerk ...

Dynamic Light Scattering is commonly used to rapidly measure the hydrodynamic size and size dispersity of nanoparticles in suspension. Several commercial DLS instruments exist, using a range of ...

Horiba has developed a particle size distribution measuring device that accurately measures particle size distribution even in the presence of similar-shaped particles. The device uses image ...
