Image: Cutaway view of nanoparticles in a neural cell

NIST's Precision Imaging Facility (PIF) in Boulder, Colo., provides a variety of advanced tools for precisely measuring the structure and chemical composition of materials at sub-nanometer scales. These images were prepared ...

Hybrid material as gold-leaf substitute

(Phys.org) —A team of researchers headed by Professor Raffaele Mezzenga has created a hybrid material out of gold and milk proteins that looks like a wafer-thin gold leaf. Thanks to its properties, it could be used in a ...

How gold nanoparticles can help fight ovarian cancer

Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why, and determined how to make the nanoparticles effective ...

Visualization of gold nanoparticle self-assembly via TEM

The self-assembly of gold nanoparticles (Au NPs) coated with specific organic ions in water was observed by Center for Nanoscale Materials staff in the Nanobio Interfaces, Electronic & Magnetic Materials & Devices, and Nanophotonics ...
