Abstract :
In this study, a simple methodology for the development and application of a solid-state sensor for the measurement of ascorbic acid (AA) by means of on paper colorimetric assay, is reported. Ink-jet printing has been used to fabricate paper strips used for the assay. An apparatus for the simple readout of the paper strips, comprising a CMOS camera which allows to acquire RGB (Red, Green, Blue) colors and an image analysis software for data elaboration, has been also developed. The printed paper strips developed allow the determination of AA in practical applications.
