Quantitative and Self-calibrating Chemical Analysis Using Paper-based Microfluidic Systems

A method of determining the concentration of a test fluid sample using a paper-based microfluidic system having a plurality of hydrophilic testing zones, including: a) depositing said test fluid sample on at least one said testing zone; b) depositing a plurality of standard fluid samples or reactives of differing known concentrations on other said testing zones; c) introducing an indicator solution to each said test zone to thereby react with the deposited fluid sample and result in a colour intensity change which is a function of the fluid sample concentration; and d) comparing the differences in colour intensity between the test fluid sample and the standard fluid samples or reactives to thereby determine the concentration of said test fluid sample.
