There has been a growing curiosity and enthusiasm surrounding recent advancements in nanotechnology, electromagnetism, and optics. This interdisciplinary collaboration encompasses fields such as nanomaterials, nanoelectronics, and nanobiotechnology, which often overlap in their applications. One area that has attracted significant attention is the use of metal nanoparticles (MNPs), which has resulted in notable advancements in medicine. MNPs hold the promise of significantly boosting drug delivery efficacy, reducing unwanted side effects, and enhancing delivery precision. They also have applications in diagnostics, the development of biocompatible materials, and the exploration of nutraceuticals. Using metal nanoparticles in drug delivery provides benefits such as increased stability, prolonged circulation time, enhanced distribution, and precise targeting. The field of nanobiotechnnolgy has facilitated the creation of eco-friendly approaches, referred to as green synthesis, for the production of MNPs. MNPs offer improved stability and targeted release in drug delivery, while also providing a more sustainable alternative to chemical synthesis. This review aims to address the challenges and prospects of utilizing MNPs in drug delivery, with a specific focus on sustainable approaches for fabricating and modifying metal nanocarriers. It also explores the application of various MNPs in drug delivery systems (DDSs).
