Today, reading up on some of the major Bionantoechnology and Medical Nanotechnology websites, I stumbled across an article describing the use of gold nanospheres in cancer treatment. This technique works by targeting 40-50nm nanospheres to melanomas via the melanocortin type 1 receptors. Once these nanospheres were bound to the melanomal cells they could be destroyed by photoablation. This technique gives far greater selectability for the cancerous cells then other techniques and has been shown in mice, to cause far less damage to surrounding cells during the photoablation.
This technique is said to have few side effects. The gold nanospheres are made out of pure gold, which has a long history of safe medical usage. Such a new technique if proven to be effective in humans could revolutionize medical treatment of cancers, which to all intents and purposes has not changed all that much since the Ancient Greek poison and removal method of cancer treatment (nowadays surgery and chemotherapy). With this tool for more efficient photoablation of cancerous cells all that would need to be done is find a way of targeting other tumor types possibly through the targeting of up-regulated cellular stress ligands.
This technology I feel has great potential for furthering our abilities to medically combat cancer. – CT
