There is growing demand for point-of-care diagnosis worldwide using low-cost, autonomous, and disposable devices. Scientists in Sweden have developed a disposable lab-on-a-chip unit that is manufactured by 3D printing technique and equipped with an integrated 3D-printed optical lens system which serves as an interface for direct readout by any regular cell phone camera. As the scientists report in the journal Angewandte Chemie, their device reliably performs quantitative chemical sensing, and the prototype is designed for colorimetric detection of the glucose concentration in a clinically relevant range.
