Fighting Cancer With A 'Nano Cocktail'

 Researchers from UC San Diego, Santa Barbara and MIT have developed a "cocktail" of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors. The team says their work, appearing in an upcoming issue of PNAS, represents the first successful effort to employ a cooperative nanosystem to fight cancer. In their study, the researchers developed a system containing two different nanomaterials the size of only a few nanometers, or a thousand times smaller than the diameter of a human hair, that can be injected into the bloodstream. One nanomaterial was designed to find and adhere to tumors in mice, while the second nanomaterial was fabricated to kill those tumors. read more
