This lab in the hand is worth two in the clinic

Do you find yourself saying, “Gee, I sure wish I had a mass spectrometer here so I could run these diagnostic tests now instead of going to a lab to analyze these samples?” Lucky for you, there’s an app for that. Well, there’s a device that presumably comes with an app, and for the small price of $550 it’ll turn your smartphone’s camera into a portable mass spectrometer. The spectral transmission-reflectance-intensity (TRI)-analyzer can analyze blood, urine, and saliva samples as accurately as most clinic-based instruments, and can perform the three most common types of tests in medical diagnostics. This has really cool public health implications in terms of portability and cost. Great job, University of Illinois bioengineers!
