Abstract
The present invention provides methods of using metal nanoparticles 0.5 to 400 nm in diameter to enhance the dose and effectiveness of x-rays or of other kinds of radiation in therapeutic regimes of ablating a target tissue, such as tumor. The metal nanoparticles can be administered intravenously, intra-arterially, or locally to achieve specific loading in and around the target tissue. The metal nanoparticles can also be linked to chemical and/or biochemical moieties which bind specifically to the target tissue. The enhanced radiation methods can also be applied to ablate unwanted tissues or cells ex vivo.
