Iranian researchers test gold nanoparticle cancer drug delivery

Nanomedicine researchers at Lorestan University in Iran say they've made progress with a new drug delivery mechanism designed to carry targeted non-chemotherapy cancer treatments. Their design calls for loading the anti-cancer drug onto a gold nanomaterial and then covering it with polymer nanolayers, the Iranian Students' News Agency reports. This process, they report, is designed to use the gold to transfer a specific light wavelength to heat. That, in turn, destroys the nanostructure layers and releases the medicine at a specific target. So far, early tests have allowed the special drug to smash cancer cells without hurting healthy tissue, unlike chemotherapy. Story
