The main idea is that a patient will swallow a pill with magnetic nanoparticles to detect various conditions. Dr. Andrew Conrad of the Google X research division is spearheading this project. These nanoparticles could potentially attach themselves to cancer cells, change color when potassium passes through them to measure the amount of it in the blood, or attach to fat build ups that could lead to heart attacks. Nanoparticles that aren’t attached to anything would behave differently than those that are, and software can ultimately be used to diagnose the patient based off the movements of the particles in a magnetic field. The results would then be readily displayed on a wearable device.
Problems have already been raised including misdiagnosis or false positives which could lead to unnecessary treatment or higher levels of anxiety. Nonetheless, Google has said that if this concept is feasible, this technology could reach the public in about five years.
