Application of Nanoparticle Drug Delivery Systems in the Medical Field: Focusing on Functionalized Gold Nanomaterials

Nanoparticle drug delivery systems are currently one of the hottest topics in the field of medicine. They can precisely deliver drugs to the parts of the patient that need treatment, with the goal of improving patient effectiveness and reducing drug toxicity. Gold nanoparticles (AuNPs) are considered one of the most promising nanomaterials due to their unique optical, electronic, sensing, and biochemical properties. By combining AuNPs with different ligands, functionalized gold nanoparticle (F-AuNPs) drug delivery systems can be obtained, which have broad application prospects in the field of medicine. This article focuses on the different ligand connection types of F-AuNPs and reviews the research progress of F-AuNPs drug delivery systems in the field of medicine in recent years.
