34. Detecting HIV
You may not realize it, but your smartphone could be used to detect serious diseases. HIV/AIDS affects more than 37 million people around the world. Early diagnosis of this disease can save lives, as access to antiretroviral medication can add ten years to someone’s life expectancy.
Researchers from the University of London have developed a disposable sensor that plugs into smartphones. This sensor holds particles that react to HIV. Within ten seconds of adding blood from a patient into the sensor’s channels, HIV can be detected. Results will be uploaded into a smartphone app and sent to a patient’s doctor.
