A Review on Gold Nanoparticles: Properties, Synthesis and Biomedical Application in Drug Delivery and Cancer Therapy

Gold nanoparticles (AuNPs) are very small particles and are made up of gold. These particles are too much small and can't see with eyes. These gold nanoparticles (AuNPs) are used in the delivery of the drug and in the treatment of cancer. This helps the drug to reach the target site of the body that's why the effectiveness of the drugs are increased. In this review paper the Properties of the Gold nanoparticles (AuNPs) including its Prepration, Synthesis method and the application of gold nanoparticles are discussed. The gold nanoparticles particles also have some unique properties such as Surface Plasmon resonance and Biocompatibility. The review paper discussed about the potential of the Gold nanoparticles in drug delivery, to enhance the therapeutic effect of AuNPs and to minimize the Adverse effect. Also the application of AuNPs in cancer therapy are Photothermal therapy, radiation therapy and the targeted chemotherapy. This review paper aims to provide the In-depth understanding of the Gold nanoparticles (AuNPs) and the gold nanoparticles play an important role in delivery of the drugs and in the treatment of cancer.
