A significant portion of the excitement in microfluidics is in its subset of paper microfluidics. Paper used as a device for point of care diagnostics brings exciting new dimensions to the medical world. It is affordable, user friendly, easily accessible and safe. To further become into diagnostic care devices, paper has to be fabricated and patterned in the best possible manner to attain the optimal resolutions in its channels for analysis. This paper aims to perfect the methodology of traditional soft photolithography for paper by altering the parameters given such that it can allow proper and quick lateral flow of fluids for further usage in electrochemistry and telemedicine. It has eventually been found that the parameters of Type 1 Whatman grade filter papers spin coated for 30 seconds at a speed of 2750 rounds per minute and exposed for 21 seconds under UV and soaked in Acetone for 5 minutes to develop and 20 seconds to plasma bond it has been the best parameters of this study.
