Platinum-based anticancer drugs have been very successful in treating certain cancers, but medical researchers would like to extend their use more generally. The extremely potent drugs cisplatin, carboplatin, and oxaliplatin all lose activity on their journey from the site of administration to the target tumor. Now, chemist Stephen Lippard of Massachusetts Institute of Technology and colleagues have demonstrated that carbon nanotubes could be used as a novel delivery agent. The nanotube could protect the platinum drug from degradation until it is released at the tumor site.
