Gold dust could be a valuable new weapon against cancer - helping to "smuggle" drugs past the body's immune system and into tumours.
Scientists have succeeded in attaching molecules of an anticancer drug to gold particles just a fraction of the width of a human hair. The particles are so small they can sneak past the body's defence mechanisms without being destroyed and deliver the cancer-killing medicine to the heart of the tumour. The new technique, being developed at Rice University in Houston, Texas, could reduce some of the more unpleasant side-effects suffered by cancer patients undergoing chemotherapy.
Many suffer hair loss, nausea and are at increased risk from infections because the toxic drugs suppress their immune system. This happens because chemotherapy drugs injected into the body attack healthy as well as cancerous tissues.
Scientists hope the gold dust therapy will reduce the amount of toxic medicine affecting the body by delivering more of it to the tumour itself.
