Combining microfluidic paper-based analytical device (μ-PAD) and the molecular imprinting technique, a visible light photoelectrochemical (PEC) sensing platform for the detection of pentachlorophenol (PCP) was established on gold nanoparticles (AuNPs) decorated paper working electrode using polypyrrole-functionalized ZnO nanoparticles. Ascorbic acid (AA) was exploited as an efficient and nontoxic electron donor for scavenging photogenerated holes under mild solution medium and facilitating the generation of stable photocurrent. The microfluidic molecular imprinted polymer-based PEC analytical origami device is developed for the detection of PCP in the linear range from 0.01 ng mL(-1) to 100 ng mL(-1) with a low detection limit of 4 pg mL(-1). This disposable microfluidic PEC origami device would provide a new platform for sensitive, specific, and multiplex assay in public health, environmental monitoring, and the developing world.
结合微流控纸基分析器件（μ-PAD）和分子印迹技术，使用聚吡咯功能化的氧化锌纳米粒子在金纳米粒子（AuNPs）修饰的纸工作电极上建立了可见的光光电化学（PEC）传感平台，用于检测五氯苯酚（PCP）。抗坏血酸（AA）被用作一种高效且无毒的电子供体，可在温和的溶液介质中清除光生空穴，并促进稳定光电流的产生。微流控分子印迹聚合物基 PEC 分析折纸装置用于检测 PCP，其线性范围从 0.01ng mL(-1)到 100ng mL(-1)，检测限低至 4pg mL(-1)。这种一次性微流控 PEC 折纸装置将为公共卫生、环境监测和发展中国家的敏感、特异性和多重分析提供一个新的平台。
