A new study by Brown University researchers suggests that gold nanoparticles—microscopic bits of gold thousands of times ...

So how does it work? The glass contains extremely small quantities of colloidal gold and silver — nanoparticles of gold to produce the red, and silver particles to make the milky green.

Colloidal nanoparticles are particles that operate at the nanoscale, specifically between 1 to 1000 nanometers, suspended in a fluid. These nanoparticles can consist of various materials, such as ...
