  author={Nahid Pourreza and Hamed Golmohammadi},
This article describes the design and fabrication of a novel lab-on-paper device for pH sensing using curcumin nanoparticles (CURNs). In order to fabricate the lab-on-paper, the wax dipping method was used. The color of loaded paper with CURNs changed from yellow to orange and red to brown in the pH range of 7-13. The image of the lab-on-paper was taken by a digital camera and the picture was processed and analyzed using Adobe Photoshop software. The change in mean color intensity with pH was… CONTINUE READING
