Biosensor `bandage` collects and analyzes sweat
(PHYSorg.com Chemistry)

Like other biofluids, sweat contains a wealth of information about what`s going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin`s surface, can be time-consuming and messy. Now, researchers have developed a bandage-like biosensor that both collects and-in conjunction with a smart phone-analyzes sweat. The device, which could someday help diagnose diseases, is reported in ACS` journal Analytical Chemistry.
