Biomedical engineers at Cornell University have added Halloysite nanotubes to a protein coated surface of a microflow device to more effectively capture circulating tumor cells in patients’ blood.  Halloysite is a naturally occurring mineral, aluminosilicate, which forms as hollow tubes smaller than 100 nanometers.  In a sense, they work like Velcro hooks on passing leukemic cells, without damaging those cells.         MORE
