Natural Gum May Make Gold Nanoparticles More Effective for Cancer Detection and Treatment

A research group from the University of Missouri found that by binding gum arabic to gold nanoparticles, the nanoparticles become safe for use in the human body. Preliminary results also showed that the nanoparticles created are able to survive in biological fluids for at least a week. Led by Kattesh Katti, PhD of the Hybrid Nanoparticles in Imaging and Therapy of Prostate Cancer Platform Partnership, the researchers mixed widely available gold salt with diluted gum arabic and a chemical reducing agent, thus creating a quick formation of gum arabic-labeled gold nanoparticles. Their work was supported by the National Cancer Institute’s Alliance for Nanotechnology in Cancer.
