Smart Theranostic Applications of Metal Nanoparticles Against Cancer

Metals such as silver, gold, and copper were used in ancient times for their medicinal properties. When these metals are converted to nanoparticles, they show unique and advanced physicochemical and biological properties due to their enhanced surface to volume ratio. Hence, these properties are utilized by researchers to develop highly specific diagnostic tools as well as a therapeutic agent against cancer. Cancer is a complex disease-causing desolation and death. Early detection and treatment is the only way to evade mortality. This chapter focuses on metal nanoparticles used as a theranostic agent against cancer. It summarizes the synthesis methodology along with their advantages, drawbacks and characterizations. Their recent application in diagnosing and treating cancer has also been highlighted.
