Colorimetric Analysis to Predict Ph Value of the Water on Mpads (Microfluidic Paper Based Analytical Devices) Testzone Area

Abstract

Microfluidic paper-based analytical devices (μPADs) are the futuristic microfluidic paper-based analytical diagnostic devices that are utilized to perform the laboratory-based test (ex: water, blood, urine, etc..,) at the user location. Microfluidic paper-based analytical devices (μPADs) are known as a robust analytical platform that can fulfil the stipulations. This analysis aims to offer a detailed assessment of the μPADs that are advanced for the estimation of vital water pH values. The significant challenge for users with the μPAD based diagnostic is that, the user is unable to evaluate the precise outcome of the diagnostic result. Here, the water pH diagnostic test is considered on the μPADs, since water pollutant is a severe environmental hassle that affect thousands of humans and as a result it increases the demand for common water first-class monitoring. The necessity for analytical systems that merge extreme sensibleness, selectivity and accuracy with low cost, portability and consumer friendliness remains as a prominent part. This research work proposes a technique to detect the pH value of the water by acquiring the images of the tested μPADs, extract the shape of the test zone area and perform colourimetric analysis to determine the pH value of the test zone area on scale 0-13. The main advantages of the μPADs are comparatively low cost and accessible abundance, reduce the overall cost of testing, and reduce the number of visits to the research laboratory.
