A portable molecularly imprinted polymer-modified microchip sensor for the rapid detection of perfluorooctanoic acid

along with satisfactory sensitivity, selectivity, and reproducibility, which reveal its great potential in the low-cost and efficient field detection of PFOA in coastal seawater. These promising results indicate a bright future for such microchip-sensor-supported PFOA tele-sensing platforms in aiding environmental safety and blue earth protection. We will persist in refining this method to enhance the sensitivity of the sensor for PFOA detection in polluted coastal areas.
