Simple and affordable ways to design and create paper-based devices using easy to find materials and equipment have been explored. Aspects of green analytical chemistry are also incorporated into this research by making use of natural reagents in chemical analysis. Filter paper was selected as a paper substrate. The design of hydrophobic and hydrophilic regions was created using sticker. Waxy materials such as petroleum jelly, candles, and crayons were tested for their feasibilities in producing hydrophobic barriers. Egg white and copper ions were selected as model natural reagent and analyte to demonstrate the performance of the developed simple paper based device. Colorimetric determination of copper ion was carried out through digital image analysis of RGB values. The paper based device should be useful for field analysis as well as for low cost teaching tool.
