US Patent 8217366 - Carbon ion generator for tumor treatment

It has been reported that carbon ions are 2.8 times higher in cancer cell kill rate than protons and are 2.5 times lower in cancer recurrence rate than X-rays or protons. This patent from the Electronics and Telecommunications Research Institute teaches a nanotechnology approach to generating high purity carbon ions which may my enable the use of carbon ion sources in cancer therapy. Claim 1 reads:

1. A carbon ion generating device comprising:

a carbon nanostructure;

a carbon emitting structure configured to induce an emission of carbon atoms from one end of the carbon nanostructure; and

an ionizing structure configured to ionize the emitted carbon atoms;

a top electrode disposed adjacent to the one end of the carbon nanostructure;

a bottom electrode connected to the other end of the carbon nanostructure; and

a power supply unit configured to create a first potential difference between the top electrode and the bottom electrode.
