Two-step nano cocktail targets tumors

• SAN DIEGO - A cocktail of nano-sized particles introduced into the bloodstream shows promise in adhering to and killing cancerous tumors, scientists in San Diego say. Scientists at the University of California-San Diego developed a system containing two nano materials, each one-thousandth the dia- meter of a human hair. One nano material of iron oxide was designed to find and adhere to epithelial tumors in mice, while a second nano material -- the anti-cancer drug doxo- rubicin -- was fabricated to kill the tumors, biochemist Michael Sailor said in a release Monday. "This study repre- sents the first example of the benefits of employing a coop- erative nano system to fight cancer," Michael Sailor said of the results, which were to be published in an upcoming issue of the Proceedings of the National Academy of Sciences.
