Résumé
Gold nanoparticles (AuNPs) have several biomedical applications in diagnosis and treating of disease such as targeted chemotherapy and in pharmaceutical drug delivery due to their multifunctionality and unique characteristics. AuNPs can be conjugated with ligands, imaging labels, therapeutic drugs and other functional moieties for site specific drug delivery application. In this present review we are discussing the synthesis, properties, and forthcoming applications of gold nanoparticle (AuNPs) which is the most studied among all other metallic-nanoparticles. Here our main focus is to explain the AuNPs application in cancer treatment. AuNPs provides non-toxic carrier system for pharmaceutical drug and gene delivery applications. Currently various anticancer drugs are available but these are cause the necrosis of cancerous cell as well as normal cells. AuNPs cause the necrosis of only cancer cells therefore we can utilize it as a delivery vehicle as well as anticancer agent.
