“…The same pattern is observed after 200 cycles, which indicates the stability and repeatability of the CuOÀ CNF electrode. Furthermore, CV analysis was conducted at different scanning rates (10,20,50, and 100 mV/sec) to explore the consequences of different scans and find suitable scan rates for further analysis in the same potential range (Figure 4d). The cathodic peaks shift toward more negative potential directions with increasing scan rate, which is a characteristic of a typical quasireversible and irreversible electrochemical system.…”

“…[19] The increasing global demand for food has augmented the dependency on pesticides, as they inhibit the growth of pests while enhancing agricultural productivity. [20] However, their excess use in agricultural practices results in their presence in soils, wastewater, ground water, surface water, and food products. Pesticides persist in the environment for a longer duration than antibiotics and are found to be carcinogenic to human health.…”

Electrochemical sensors offer promising prospects for real‐time pollutant monitoring. In this study, copper oxide‐dispersed graphitic carbon nanofibers (CuO‐CNFs) grown via chemical vapour deposition were employed as a robust platform for detecting a variety of environmental pollutants. This array‐based sensor adeptly identifies three different classes of analytes, i.e., antibiotics (chloramphenicol (CP) and tylosin tartrate (TT)), heavy metals (cadmium (Cd) and lead (Pb)), and pesticides (quinalphos (QP) and imidacloprid (IP)). The CuO‐CNF‐modified GCE array rapidly discerns (<15 sec) a broad linear range: 1‐20 ppm for CP, 1‐13.33 ppm for TT, 0.66‐11.66 ppm for Cd, 20‐33.33 ppm for Pb, 1.6‐11.6 ppm for QP, and 5‐25 ppm for IP, boasting quantification limits of 1.0, 1.0, 0.66, 20.0, 1.6, and 5.0 ppm for CP, TT, Cd, Pb, QP, and IP, respectively. Notably, this sensor achieves simultaneous identification of mixed analytes, including CP and TT, Cd and Pb, and QP and IP, within real tap water. The electrochemical sensor exhibits robustness; heightened sensitivity, selectivity, and stability; swift response; and impressive reproducibility in detecting CP, TT, Cd, Pb, QP, and IP within aqueous samples. Consequently, this array‐based electrochemical sensor has emerged as a rapid and simultaneous detection tool for diverse pollutant residues in surface and groundwater samples.

“…Nanomaterials, due to their special structure and a series of unique physical and chemical properties, are widely used in chemosensors, e.g., for the fixation of active molecules, signal detection, and transmission amplification; greatly improve the sensitivity; shorten the response time; and achieve high-throughput real-time detection, providing a new research path and huge space for the development of chemosensors [62][63][64][65][66][67][68][69]. NFs have become a hot spot in sensing research due to their unique structure, and the electrospinning process can directly and continuously prepare polymer NFs [70][71][72][73].…”

Electrospun nanofibers have shown their advantages for applications in a wide variety of scientific fields thanks to their unique properties. Meanwhile, electrospinning is closely following the fast development of nano science and nanotechnology to move forward to smaller (pico-technology), more complicated nanostructures/nanodevices and more order (all kinds of nano arrays). Particularly, multiple-fluid electrospinning has the strong capability of creating nanostructures from a structural spinneret in a single-step and a straightforward “top-down” manner, holding great promise for creation on a large scale. This review is just to conclude the state-of-art studies on the related topics and also point out that the future directions of environmental detection require chemosensors, while the improvement of sensors requires new chemically synthesized functional substances, new nanostructured materials, application convenience, and functional integration or synergy. Based on the developments of electrospinning, more and more possibilities can be drawn out for detecting environmental pollutants with electrospun nanostructures as the strong support platform.
