007skaty Superparamagnetic Nanoparticles
When magnets shrink to nano size, they lose their grip, And thermal energy can make their poles just flip.
007skaty Localized surface plasmon resonance makes electrons in tiny gold nanoparticles vibrate with light waves, changing the colors they absorb and reflect.
007skaty This extreme surface exposure drives incredibly fast and powerful chemical reactions.
007skaty Resize your quantum buddies to discover how nanoparticle size controls their glowing colors.
Size comparison: If a nanoparticle were the size of a soccer ball, a regular soccer ball would be the size of the Earth!
A microscopic particle of matter that has at least one dimension between 1 and 100 nanometers. In 1857, Michael Faraday created red colloidal gold, demonstrating how shrinking the metal altered its physical properties.
