Tiny laser-powered sensor-on-a-chip tests chemical composition of liquids

They are invisible, but perfectly suited for analyzing liquids and gases; infrared laser beams are absorbed differently by different molecules. This effect can for instance be used to measure the oxygen concentration in blood. At the Vienna University of Technology, this technique has now been miniaturized and implemented in the prototype for a new kind of sensor.
