Gold nanoparticles (AuNPs) are nanoscale particles of gold, typically ranging in size from 1 to 100 nanometers (nm). These nanoparticles exhibit unique physical, chemical, and optical properties that ...

Spherical and star-shaped gold nanoparticles (top) and colon cancer cells after approx. five hours of exposure to them (bottom, respectively). The photo in the bottom left corner proves that, despite ...

While Raman spectroscopy has been hugely successful in a number of domains of chemistry and materials science, 1-3 one of the main challenges with performing Raman measurements is the inherently weak ...

In the form of a ‘nasal spray’, tiny gold particles act as carriers, delivering a treatment directly to the brain: developed by scientists at the Università Cattolica Rome campus/Fondazione ...

As Sujan Manna searched for tiny, spherical gold nanoparticles against a dark-field backdrop, he came across an unexpected ...

According to a study published in Advanced Functional Materials on November 24 th, 2024, a group of researchers led by Assistant Professor Andy Tay from the Department of Biomedical Engineering in the ...

A new study by Brown University researchers suggests that gold nanoparticles - microscopic bits of gold thousands of times thinner than a human hair - might one day be used to help restore vision in ...

Mesmerizing videos offer a new look at the ways crystals form. The real-time clips, described March 30 in Nature Nanotechnology, show closeup views of microscopic gold particles tumbling, sliding and ...

Scientists have found a way to boost terahertz technology using particles thousands of times smaller than a grain of sand.
