  • Publication number: 20100113861
    Abstract: A process or method for treating cancer. In one embodiment, the method includes the steps of providing a plurality of metallic nanoparticles, wherein each of the plurality of metallic nanoparticles has a core formed with a first metallic material, and a shell formed with a non-metallic material containing carbon, and wherein the shell is formed to enclose the metallic core completely, introducing said metallic nanoparticles into a mammal such that said metallic nanoparticles selectively target at least one type of cancerous cell, and subsequently applying at least one radio frequency of electromagnetic waves to said mammal for a period of time effective to induce skin currents in the cores of the first metallic material of said metallic nanoparticles to cause heat generated locally around targeted at least one type of cancerous cell to kill said cancerous cell.
