Chemotherapy is administered, weakening both patient and cancer cells. But the cancer does not die; it comes back and eventually kills the patient.

Now imagine another scenario. After surgery, strands of DNA anchored in tiny gold particles are injected into the affected area. The DNA strands bind to the tumor cells, killing them directly, without the help of chemo. The healthy cells around the tumor cells, which don’t express the tumor gene, are untouched. Just like that, all the tumor cell stragglers are rendered harmless, corrected on the genetic level.
