Review on the production and applications of gold nanoparticles as a drug delivery carrier

Abstract

There are numerous medicinal and industrial uses for nanoparticles in the detection and treatment of disease. Nanoparticles stand out for their ability to perform multiple tasks and their small size. It is possible to use nanoparticles to deliver drugs to specific sites in the body, as well as to increase cellular absorption. Gold nanoparticles, which are the most extensively investigated of all metallo-nanoparticles, are the focus of this review. Anti-cancer medications are available; however, necrosis of both malignant and non-cancerous cells is a side effect of many of them. The necrosis caused by gold nanoparticles affects exclusively cancer cells. Smaller than human cells, these tailored drug delivery devices can quickly infiltrate tumors and kill malignant cells. Anticancer medicines that have been conjugated with gold nanoparticles are more effective. Due to their photophysical and optical properties, gold nanoparticles are useful in chemotherapy and cancer diagnostics. Proteins, peptides, and nucleic acids can all be used to modify gold nanoparticles. Such devices have a wide range of applications, from biosensors to medication administration.
