Read moreResearchers disguise drugs as platelets to target cancer
Researchers have for the first time developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize. The work was tested successfully in an animal model.
