Gold Colloid Solution, or Colloidal Gold, is a suspension of gold nanoparticles typically ranging from 1 to 100 nanometers in size. These nanoparticles exhibit distinct optical and electronic properties, making them valuable in fields like biomedicine, diagnostics, sensors, and catalysis. Unlike bulk gold, their nanoscale behavior is influenced by quantum effects and a high surface area-to-volume ratio. Colloidal gold is synthesized by reducing gold salts in solution using agents that stabilize the particles and prevent clumping.
