Google is experimenting with placing nanoparticles inside a pill to search for malignant cells in a patient’s bloodstream. A patient swallows the pill and a sensor on a wearable device reports back findings to a doctor providing better insight into what is happening inside their patient’s body.
The nanoparticles are coated with antibodies that would attach to specific proteins or cells. The particles would remain in the blood supply and continuously report data back to the sensor. The sensor would also track the particle’s movement through the body using magnetic fields. The goal of the project is to give doctors more information about a patient’s health compared to results of a blood sample.
