More Nano Weapons to Fight Cancer

Roland Piquepaille writes "In this article, the MIT Technology Review says that different new nanotools will help us to diagnose or kill cancerous tumors. 'Nanoshells' invented at Rice University could become an alternative to chemotherapy by killing only cancerous cells after injection into patients' bloodstream. And nanoparticles created at the University of Washington in Seattle could be used to noninvasively diagnose and treat brain tumors. Meanwhile, a biochemist from Brigham Young University has developed "a method for examining mutations in DNA to determine a person?s genetic predisposition for developing cancer." This overview contains more details and a diagram showing how nanoshells are conjugated with antibodies to kill cancerous cells. [Note: Previous results about nanoshells were reported here by Nanodot in February.]"
