An Overview of Noble Metal Nanoparticles and Their Application in the Treatment of Cancer Diseases

Noble metals and their compounds have been used as therapeutic agents since ancient times in medicine to treat various infections. Recently, many advances have been made in the field of nanotechnology to develop different types of nanomaterials with a wide range of applications. Among metal nanoparticles, noble metal nanoparticles have shown potential biomedical applications. Due to their small size, nanoparticles can easily communicate with biomolecules both on the surface and inside cells and bring better targeting for diagnosis and treatment. Noble metal nanoparticles inspire researchers due to their significant role in the diagnosis and treatment of unpleasant diseases. In this review article, we focus on the biomedical applications of noble metal nanoparticles, especially silver, gold, and platinum, in cancer diagnosis and treatment.
