Individuals have never been better informed about potential threats to their health. A quick look at one’s phone can reveal body temperature, heart rate, air quality, and even information about potentially harmful noise and light exposure. However, real-time data of chemical exposures that can substantially affect health & well-being remain painfully opaque due to a stagnation in molecular monitoring technology. DIA aims to expand the Internet of Things to include real-time measurements of endogenous and exogenous chemicals from portable and wearable sensors to better protect individual and public health.
