Role of Gold Nanoparticles in Drug Delivery

Abstract

Recent developments in nanotechnology offer a multitude of approaches for investigating and tracking diverse biological and medical processes at the nanoscale. Nanoparticles can deliver medications directly to cancer cells, aiding in the diagnosis and treatment of diseases like cancer. Gold nanoparticles (AuNPs) are incredibly small gold particles, usually fewer than 100 nanometers in size. They are measured in nanometers. AuNPs are one type of nanoparticle that has shown promise as a medication delivery platform. Their outstanding stability, adjustable chemical and physical characteristics, and biocompatibility make them incredibly beneficial for drug delivery applications. The physical and chemical features of AuNPs' natural characteristics were studied. Localized surface plasmon resonance (LSPR), radioactivity, and a high X-ray absorption coefficient are among the physical characteristics of AuNPs that are commonly used in diagnosis and treatment. Compared to many other nanoparticles, AuNPs can create stable chemical interactions with groups that contain S and N. As a result, AuNPs can bind to a broad range of chemical ligands or polymers used for particular purposes. According to recent research, AuNPs can be easily modified to allow the delivery of pharmaceutical drugs directly to the target tissue. This article provides a brief overview of the more effective synthesis method for AuNPs and how they can be utilized as drug carriers to improve precision medicine.
