A major milestone has been reached in nanomedicine drug delivery in Australia, with researchers at the Australian National University (ANU) successfully controlling the release of a drug using light. This breakthrough has the potential to revolutionize drug delivery for cancer and other diseases, allowing doctors to precisely control the release of medication to target specific cells. The research team used gold nanorods and a fluorescent dye to control the release of a cancer drug called doxorubicin. When exposed to near-infrared light, the gold nanorods absorbed the light and generated heat, which caused the drug to be released from the nanorods. This allowed for highly targeted drug delivery, which reduced the side effects of the drug while still maintaining its effectiveness.
