Investigation of liquid flow interaction on wax and cut channel paper-based microfluidic analytical device (μpad)
Simple, user-friendly, economical and rapid sensing devices are in urgent demand for diagnostics purposes especially in resource-limited countries. Diagnostics devices fabricated from patterning paper into hydrophilic and hydrophobic regions called paper-based microfluidic analytical devices (μPADs)...

For wax channel, wax hydrophobic channel is drawn on the upper side of the paper and heated for 3 minutes on 100 °C of hotplate for the diffusion of wax into the thickness of paper. 10 different viscosities of sucrose solution ranging from 0% to 70% of solute with additional of 2 blind samples is pipetted into the wax and cut channel and left horizontally for liquid flow in a minute.
