Bisphenol A is one the most relevant endocrine disruptors for its toxicity and ubiquity in the environment, being largely employed as raw material for manufacturing processes of a wide number of compounds. Furthermore, bisphenol A is released in the drinking water when plastic-based bottles are incorrectly transported under sunlight, delivering a contaminated drinking water. For the health of human beings and the environment, a rapid and on site detection of bisphenol A in drinking water is an important issue. Herein, we report a novel and cost-effective printed electrochemical sensor for an enzymatic-free bisphenol A detection. This sensor encompasses the entire electrochemical cell printed on filter paper and the reagents for the measurement loaded in the cellulose fibers network, for delivering a reagent-free analytical tool. The working electrode was printed using ink modified with carbon black, a cost effective nanomaterial for a sensitive and sustainable bisphenol A determination. Several parameters including pH, frequency, and amplitude were optimized allowing for a detection limit of 0.03 μM with two linear ranges 0.1–0.9 μM and 1 μM–50 μM, using square wave voltammetry as electrochemical technique. The satisfactory recovery values found in river and drinking water samples demonstrated the suitability of this sensor for screening analyses in water samples. These results revealed the attractiveness of this paper-based device thanks to the synergic combination of paper and carbon black as cost-effective materials.

双酚A是最相关的内分泌干扰物，因为它具有毒性和在环境中的普遍性，被广泛用作各种化合物生产过程的原料。此外，当塑料瓶在阳光下不正确运输时，双酚A会释放到饮用水中，从而输送受污染的饮用水。为了人类和环境的健康，饮用水中双酚A的快速，现场检测是一个重要的问题。在此，我们报告了一种新型且经济高效的印刷电化学传感器，用于无酶双酚A检测。该传感器涵盖了印刷在滤纸上的整个电化学电池以及用于纤维素纤维网络中的用于测量的试剂，用于交付无试剂的分析工具。使用炭黑改性的油墨印刷工作电极，炭黑是一种灵敏且可持续的双酚A测定方法，是一种经济高效的纳米材料。使用方波伏安法作为电化学技术，对包括pH，频率和幅度在内的多个参数进行了优化，允许检测限为0.03μM，两个线性范围为0.1–0.9μM和1 μM–50μM。在河流和饮用水样品中发现的令人满意的回收率值证明了该传感器适用于筛查水中的样品。这些结果揭示了这种纸基设备的吸引力，这要归功于纸和炭黑作为具有成本效益的材料的协同组合。使用方波伏安法作为电化学技术，对包括pH，频率和幅度在内的多个参数进行了优化，允许检测限为0.03μM，两个线性范围为0.1–0.9μM和1 μM–50μM。在河流和饮用水样品中发现的令人满意的回收率值证明了该传感器适用于筛查水中的样品。这些结果揭示了这种纸基设备的吸引力，这要归功于纸和炭黑作为具有成本效益的材料的协同组合。使用方波伏安法作为电化学技术，对包括pH，频率和幅度在内的多个参数进行了优化，允许检测限为0.03μM，两个线性范围为0.1–0.9μM和1 μM–50μM。在河流和饮用水样品中发现的令人满意的回收率值证明了该传感器适用于筛查水中的样品。这些结果揭示了这种纸基设备的吸引力，这要归功于纸和炭黑作为具有成本效益的材料的协同组合。在河流和饮用水样品中发现的令人满意的回收率值证明了该传感器适用于筛查水中的样品。这些结果揭示了这种纸基设备的吸引力，这要归功于纸和炭黑作为具有成本效益的材料的协同组合。在河流和饮用水样品中发现的令人满意的回收率值证明了该传感器适用于筛查水中的样品。这些结果揭示了这种纸基设备的吸引力，这要归功于纸和炭黑作为具有成本效益的材料的协同组合。
