Comparison of Some Modern IT Equipment as Detectors for Microfluidic Paper-based Determination of Phosphate

Modern Information Technology (IT) and communications equipment (mobiles phones, scanners, etc) may all be used as image capture devices for paper-based colorimetric analysis. This paper evaluates the use of a mobile phone, a webcam, a flatbed scanner and a handheld scanner as image capture devices...
