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 ...

Assumptions: Spherical gold nanoparticles dispersed in water (n = 1.333). Results are most accurate for monodisperse, citrate-stabilized AuNPs. Surface coatings may shift λ SPR by several nm.

Occasionally referred to as ‘colloidal gold,’ gold colloid is a suspension comprising sub-micron gold nanoparticles suspended in a solvent - most commonly water. Gold nanoparticles' distinct ...

Metal nanoparticles are nanoscale structures composed of metals such as gold, silver, platinum, and copper. These particles typically range in size from 1 to 100 nanometers and exhibit unique physical ...
