Rapid diagnostic test (rdt) kits are not commonly available for many diseases prevalent in developing countries like ours. even for such kits, the test procedures can be labour and time intensive, requiring expert supervision all the time. the present paper-and-pencil diagnostic device is low-cost miniaturized (due to the innovative fabrication methodologies) and efficient (high throughput rate and multiplexable) device, which does not require an elaborate infrastructure and trained on-field pathologists through the implementation of colorimetric quantitative detection techniques (unlike the majority of the available rdt kits which are qualitative in nature).
