ABSTRACT

This review is about the overview of synthesizing, characteristics and application of gold nanoparticles in the medical field. Nanoparticles are very tiny in size ranging from 1 to 100nm. The small gold particles showed an unusual optical property because of their small size and high surface area to volume ratio. These particles have been widely used in the medical field such as treatment of cancer, tumor detection, treatment of lungs cancer, drug delivery, optical biosensor, electrochemical biosensor, MRI and diagnosis of different types of major and minor diseases. Gold nanoparticles have particles size ranging from 1nm up to 150nm. The properties of gold nanoparticles are different from their bulk form. While bulk gold is yellow, the Nanoparticles of gold are wine red solutions. Gold nanoparticles inhibit oxidation. The properties of these particles are determined by their inter-particle interactions. Gold nanoparticles are advantageous in transporting and unloading drugs. Their unique physical and chemical properties make them ideal for transporting and unloading various drugs. Their photodynamic properties can trigger the release of drugs at remote locations. Their large surface area makes them suitable for various biomedical applications. Numerous medical plants have shown the potential to produce stable gold nanoparticles within a few seconds.
