Researchers from Brazil’s UNICAMP and University of São Paulo have developed a wearable plant sensor fabricated on a paper substrate using the laser-scribed graphene (LSG) technique to detect paraquat (PQ) in crops.
A synergistic effect was observed due to the combination of colorless nail polish and the chemically treated paper substrate, resulting in high-performance, conductive carbon-based graphene tracks attributed to the porous nature of the electrode fabrication process. The device detects PQ by square wave voltammetry (SWV) at concentrations ranging from 0.5 to 100.0 μmol L-1 in a 0.1 mol L-1 Britton-Robinson (BR) buffer (pH 9.0), with a limit of detection (LOD) of 0.082 μmol L-1.
