Gold nanoparticles may pan out as tool for cancer diagnosis

f routine and cost-effective procedure for the identification of cancer cells. A patient gives blood, from which cancer cells are obtained. Nanorods are then added to bind to specific markers, if present. Next, the cells are placed on a microscopic slide for imaging. After the rods absorb and re-emit radiation, a special camera records the scattered light, which a computer helps to analyze. Finally, based upon the data, a diagnosis is made.
