Abstract

Bisphenol A (BPA) exposure poses significant health risks, making its analysis essential. This study presents a portable electrochemical sensing platform using copper nanoparticles (CuNPs) decorated on a laser-induced graphene (LIG) electrode (CuNPs@LIGE). The platform is created through a one-step laser-induced synthesis that combines polyimide and metal precursors, resulting in a three-dimensional porous structure. The sensor utilizes linear scan voltammetry for BPA detection with a smartphone-connected electrochemical workstation. The presence of CuNPs in LIG enhances electrical conductivity and response signals. Under optimal conditions, the sensor achieves a detection range from 0.1 μmol/L to 10.0 mmol/L and a low detection limit of 0.033 μmol/L (3σ), demonstrating good stability and selectivity. Additionally, it shows recovery rates between 95.71% and 99.17% for BPA detection in seawater samples, making it a strong candidate for rapid BPA monitoring applications.

暴露于双酚 A (BPA) 会对健康造成严重危害，因此对其进行分析至关重要。本研究利用装饰在激光诱导石墨烯（LIG）电极（CuNPs@LIGE）上的铜纳米粒子（CuNPs），提出了一种便携式电化学传感平台。该平台是通过一步激光诱导合成法创建的，它结合了聚酰亚胺和金属前体，形成了三维多孔结构。该传感器利用线性扫描伏安法检测双酚 A，并与智能手机连接的电化学工作站相结合。LIG 中 CuNPs 的存在增强了导电性和响应信号。在最佳条件下，传感器的检测范围为 0.1 μmol/L 至 10.0 mmol/L，检测限低至 0.033 μmol/L (3σ)，显示出良好的稳定性和选择性。此外，它在海水样品中检测双酚 A 的回收率在 95.71% 到 99.17% 之间，是快速监测双酚 A 应用的理想选择。
