Record high two million gold nanoparticles inserted into a single cancer cell

By changing the organic molecule that coats gold nanorods, scientists at Rice University in Houston have increased the number of gold nanorods inserted into a single, living cell to over 2 million. The previous record was 150,000. This achievement could greatly improve photothermal therapy for cancer, which uses near-IR light to heat nanorods inside cancer cells to destroy them.
