  • Diagnostic and therapeutic nanoparticles
    Publication number: 20110064676
    Abstract: The present invention relates to diagnostic and therapeutic nanoparticles. More particularly, the present invention relates to creating a hybrid gold/gold sulfide nanoparticle with a chitosan matrix surrounding the metallic nanoparticle and a method for making the same. The chitosan-coated gold/gold sulfide nanoparticles can then be incorporated with additional therapeutic or diagnostic compounds such as iodine, antibodies, or other suitable compounds. The nanoparticles of the present invention have the dual capabilities of absorbing near infrared wavelength light to (1) act as a therapeutic agent by generating heat energy effective for cell ablation or for release of therapeutic compounds embedded in the chitosan matrix and (2) creating diagnostic benefit by incorporation of X-ray or MRI contrast-agents.
