Endocrine-disrupting chemicals (EDCs) are emerging pollutants whose uncontrolled release in natural aquatic environments can pose risks to human and animal health. In this scenario, the development of simple, low-cost, and sensitive methods to detect trace amounts of EDCs in the environment is highly sought. In this work, a nanofiber-based sensor was fabricated by functionalizing a polyacrylonitrile (PAN) electrospun nanofibrous membrane with reduced graphene oxide (rGO) to be used as a flexible and free-standing electrode to detect EDCs through electrical impedance measurements. The rGO was obtained from graphene oxide using a hydrothermal route, while the PAN/rGO composite membrane was prepared through vacuum filtration. The rGO provided high electrical conductivity to the membrane, which presented a good performance in the detection of endocrine hormones. The electrical resistance variation enabled the detection of 17αethinylestradiol (EE2) in a linear range between 10−5 and 10−11 mol L−1 . Moreover, by using the principal component analysis (PCA) for data treatment, the sensor was able to discriminate EE2, estrone, estradiol, and progesterone at 100 pmol L−1 in real river water samples. These results open up the possibility to fabricate in a simple way functionalized nanofibrous membranes to be used as sensing material for the detection of varied analytes with high sensitivity and low cost. |
