Application of gold nanoparticles in biomedical researches and diagnosis

Abstract

Gold nanoparticles have been widely used in biomedical research and diagnosis for their good biocompatibility, high surface areas, nontoxic and unique physicochemical properties. This article reviews the applications of gold nanoparticles in the detection of pathogens, proteins, toxic substances, and drug analyses, and in the preparation of biosensors, treatment of disease, and etiological analysis. The application of gold nanoparticles will have broader applications in biomedical research and diagnosis along with a deeper research into AuNPs and more findings in its novel special properties.
