More cancer-killing gold found in gold nanoparticles?

The value of gold seems to rising in the war on cancer. Last month there were reports that a group at the Georgia Institute of Technology showed in lab tests that gold nanoparticles were able to slip into the nuclei of cancer cells and trigger a cellular death process known as apoptosis. More recently, scientists at Syracuse University say that they have engineered gold nanoparticles with attached DNA that binds to the chemotherapy drug doxorubicin, aiming to improve delivery of the drug to tumors while avoiding healthy tissues.
