BREAKING: Cure for Cancer Discovered – Gold-plated Nano-particles

Gold-Plated Nano-particles Seek and Destroy Cancer Cells

In a recently published study, researchers from Cornell University detail how they developed gold-plated nano-particles that are able to find and destroy cancer cells.

Comparable to nano-scale Navy Seals, Cornell scientists have merged tiny gold and iron oxide particles to work as a team, then added antibody guides to steer the team through the bloodstream toward colorectal cancer cells. And in a nanosecond, the alloyed allies then kill the bad guys – cancer cells – with absorbed infrared heat.

This scenario is not science fiction – welcome to a medical reality.

“It’s a simple concept. It’s colloidal chemistry. By themselves, gold and iron-oxide alloys are benign and inert, and the infrared light is low-power heating,” said Carl Batt, Cornell’s Liberty Hyde Bailey Professor of Food Science and the senior author on the paper. “But put these inert alloys together, attach an antibody to guide it to the right target, zap it with infrared light and the cancer cells die. The cells only need to be heated up a few degrees to die.”

Batt and his colleagues – Dickson K. Kirui, Ph.D. ’11, a postdoctoral fellow at Houston Methodist Research Institute and the paper’s first author; Ildar Khalidov, radiology, Weill Cornell Medical College; and Yi Wang, biomedical engineering, Cornell.

For cancer therapy, current hyperthermic techniques – applying heat to the whole body – heat up cancer cells and healthy tissue, alike. Thus, healthy tissue tends to get damaged. This study shows that by using gold nano-particles, which amplify the low energy heat source efficiently, cancer cells can be targeted better and heat damage to healthy tissues can be mitigated. By adding the magnetic iron oxide particles to the gold, doctors watching MRI and CT scanners can follow along the trail of this nano-sized crew to its target.
