Researchers from Ohio State University have developed a coating that allows small sensors to function even when in contact with blood, bodily fluids, or living tissue. Currently, the electrical signals in silicon-based, implantable sensors are disrupted by the electrolytes in the body, resulting in unreliable readings. This new, ultra-thin coating blocks the electrolytes and allows the sensors to continue functioning accurately within the body. These coated sensors are first slated to be used to detect early stages of organ transplant rejection, but could have a lot of other possible applications in the future.
