The application of gold nanoparticles in biomedicine

Abstract

In the past few years, nano particles are one of the most popular scientific research fields.  It has been widely used in biomedical, optics, electronics and other areas. Gold nanoparticles are quite different from other nanoparticles. Their practical application has a very long history, which has been recorded in ancient Rome. By using their scattering property, gold nanoparticles are added to glass products to make them not only have various colors, but also have photochromic effect. With the development of related fields such as new organic metal chemistry, nanotechnology, and complex research, gold nanoparticles are listed as an important research object in biomedical applications. The shape and size of gold nanoparticles have a direct impact on their optical properties and applications. Therefore, exploring the preparation method to achieve controllable preparation is of great significance for the research of gold nanoparticles. Moreover, the application research of nano gold in biomedicine filed has developed rapidly, especially in recent years. Gold nanoparticles play an increasingly important role in disease detection, targeted therapy, drug detection, enhanced device performance, and imaging. This work mainly discusses the preparation method of gold nanoparticles and its applications in biomedicine field.
