Purdue engineer Babak Ziaie shows the prototype wireless device he has developed with doctoral student Chulwoo Son at the university's Birck Nanotechnology Center. The technology will be shrunk to the size of a rice grain so that devices can be implanted into tumors to tell doctors the precise dose of radiation being received through therapy and to locate a tumor's exact position during treatment.
