With Gold Nanos, Scientists Inch Closer to Cancer Treatment

Scientists have developed smart gold nanomaterials, which can disrupt the blood supply to cancerous tumors. The team of researchers showed that a small dose of gold nanoparticles can activate or inhibit genes that are involved in angiogenesis – a complex process responsible for the supply of oxygen and nutrients to most types of cancer. The team also controlled the degree of damage to the endothelial cells using laser illumination. Endothelial cells construct the interior of blood vessels and play a pivotal role in angiogenesis. The researchers also found that the gold particles could be used as effective tools in cellular nanosurgery.
