Synthesis of Gold Nanoparticles Using Titania Functionalized-Phosphotungstic Acid and Sodium Citrate
Colloidal metals, otherwise known as metallic nanoparticles, have many applications in optoelectronics, semiconductors, catalysis, and magnetic devices, while colloidal gold specifically has applications in drug delivery and health care due to its generally non-toxic characteristics. The functionality of a nanoparticle depends on the material in use as well as the size and surrounding environment.
