A novel way to detect toxins in water
The first ever paper microbial fuel cell (pMFC) fabricated by screen-printing carbon electrodes onto a single sheet of paper. Low-cost, fast and simple to use and with no detrimental effects on the environment, it can detect compounds such as formaldehyde. Sensor performance can be enhanced by folding back-to-back two pMFCs electrically connected in parallel.
