AB - Glyphosate, a widely used herbicide, poses significant environmental and health risks due to its persistence in soil and water. The demand for scalable and sensitive detection methods has led to the exploration of advanced sensing materials. Here, we present a flexible and sustainable graphene-copper nanoparticle (G: Cu) sensor fabricated via a spray-coating process of liquid-phase exfoliated graphene ink (0.7 mg/mL) on polyimide and graphene paper, followed by physical vapor deposition of ultra-thin Cu films and Intense Pulsed Light (IPL) photonic de-wetting to form uniform nanoparticles. This route enables precise nanoparticle size control and yields electrodes with low sheet resistance (300 Ω/sq.) and high mechanical stability, even after electrochemical cycling. Multiple cyclic voltammetry tests in 1 mM glyphosate solutions exhibited distinct redox peaks, indicating a strong interaction between the analyte and the electrode surface. Unlike previous graphene-Cu systems, this work combines solution-processable graphene deposition, scalable nanoparticle patterning, and flexible substrate integration, offering a low-cost, robust platform for real-time environmental monitoring of glyphosate contamination.
