Gold Nanoparticles: A new approach for cancer detection

Abstract

Gold nanoparticles are produced in a liquid ("liqui d chemical methods") by reduction of chloroauric acid (H[AuCl 4 ]), although more advanced and precise methods do e xist. Gold nanoparticles are also found to distinguish between cancer cells and noncancerous cells. Another benefit is that the results are instantaneous. “If you take cells from a cancer stricken tissue and spray them with these gold nanoparticles that have this antibody you can see the results immediately. The scattering is so strong that you c an detect a single particle. The interaction between light and gold nanostructures is not only u seful for the treatment of cancer but also for its diagnosis .
