Paper microfluidic device fabrication

Abstract

Paper Micro -fluidic Devices is continuously being researched and developed

since it provides abundant advantages to the society. Some applications include medical

and clinical diagnostics and assays. Its cheap commercialization value allows it to be a

highly attractive device. The main focus of this project is to investigate the best

parameters in fabricating a channel on paper via Photolithography. Successful results

were obtained where the flow of fluid was consistent from one end of the channel to the

other. The resulting optimum parameters are fabrication on Whatman 1 paper, spin

coating intensity of 2750 rpm, UV exposure for 21 seconds, washing of SU8 photo resist

with Acetone for 5 minutes and plasma cleaning for 30 seconds. Suggestions and future

directions of further research and developments were highlighted.
