Tiny delivery system with a big impact on cancer cells

Researchers in Pennsylvania are reporting for the first time that nanoparticles 1/5,000 the diameter of a human hair encapsulating an experimental anticancer agent, kill human melanoma and drug-resistant breast cancer cells growing in laboratory cultures. The discovery could lead to the development of a new generation of anti-cancer drugs that are safer and more effective than conventional chemotherapy agents, the scientists suggest. The research is published in the 10 December issue of ACS' Nano Letters, a monthly journal...
