Contaminated water leads to serious health problems and environmental issues. Paper is ideally suited for point-of-care testing, as it is low cost, disposable, and multi-functional. Initial sensor designs were manufactured on paper substrates using combinations of inkjet printing and screen printing technologies using silver and carbon inks. Bismuth onion-like carbon nanoparticle ink was manufactured and used as the active material of the sensor for both commercial and paper-based sensors, which were compared using standard electrochemical analysis techniques. The results highlight the potential of paper-based sensors to be used effectively for rapid water quality monitoring at the point-of-need.enPaper-based electrochemical sensorsPrinted sensorsElectrochemistryHeavy metal detectionWater quality monitoringConference PresentationSmith, S., Bezuidenhout, P., Mbanjwa, M., Zheng, H., & Conning, M.
