ABSTRACT
This chapter discusses hybrid gold nanoparticles and their synthesis, theranostic applications, and toxicity. It provides a detailed discussion on hybrid gold nanoparticles synthesis methods, applications in imaging, targeting delivery, plasmonic photothermal and photodynamic therapy effects, and toxicity. Nanotechnology deals with particles which have the small size between 1 to 100 nm that emerged in all of the scientific fields. Hybrid nanomaterials are composed of two or more components that involve organic or inorganic nanomaterial with other molecules. These materials, which are composed of various molecules, provide unique properties and characteristics. Graphene–gold hybrid nanoparticles have various applications in diagnostic and biomedical devices and provide synergistic properties. Engineered or hybrid nanoparticles have a lot of applications in clinical treatment, imaging, and biosensor detection devices like rapid detection tests.
