Did Google just patent a cancer-killing wristband?

Google is known more as an Internet company that dabbles in hardware and other services, but for the past year or so the company has been expanding more and more into the realm of health and medicine. In fact, Google may have a cure for cancer. According to a new patent, the company is working on a device that uses something called “nanoparticle phoresis” to remove cancer from your body. 

Google has filed a patent application with the World Intellectual Property Organization (WIPO) for a wrist-worn device that could destroy cancer cells in the blood. The patent application, which has the name “Nanoparticle Phoresis”, describes a wearable device that “can automatically modify or destroy one or more targets in the blood that have an adverse health effect”. These targets could include enzymes, hormones, proteins, cells or other molecules that, when present in the blood, may affect a medical condition or the health of the person wearing the device. The wearable device is able to modify or destroy the cells by transmitting energy into the blood vessels. The transmitted energy could be a radio frequency pulse, a time-varying magnetic field, an acoustic pulse, an infrared or visible light signal. This energy brings about a physical or chemical change in the targets, with the aim of reducing or eliminating adverse health effects.
