“…Non-specific bare electrodes typically limit the performance of the electrodes, modification strategies must be introduced to improve their performance. On the one hand, modifying the electrode surface by physical or chemical means can improve the hydrophilicity of the electrode–solution interface and thereby increase the concentration of antibiotics in the sensing area [ 209 , 210 ]. Functional materials such as nanomaterials, organic materials, enzymes, or antibodies are assembled on the electrode surface through modification methods such as self-assembly, coating, electrodeposition, and electropolymerization.…”

Rapid industrialization is accompanied by the deterioration of the natural environment. The deepening crisis associated with the ecological environment has garnered widespread attention toward strengthening environmental monitoring and protection. Environmental sensors are one of the key technologies for environmental monitoring, ultimately enabling environmental protection. In recent decades, micro/nanomaterials have been widely studied and applied in environmental sensing owing to their unique dimensional properties. Electrospinning has been developed and adopted as a facile, quick, and effective technology to produce continuous micro- and nanofiber materials. The technology has advanced rapidly and become one of the hotspots in the field of nanomaterials research. Environmental sensors made from electrospun nanofibers possess many advantages, such as having a porous structure and high specific surface area, which effectively improve their performance in environmental sensing. Furthermore, by introducing functional nanomaterials (carbon nanotubes, metal oxides, conjugated polymers, etc.) into electrospun fibers, synergistic effects between different materials can be utilized to improve the catalytic activity and sensitivity of the sensors. In this review, we aimed to outline the progress of research over the past decade on electrospinning nanofibers with different morphologies and functional characteristics in environmental sensors.

“…Top-down modifications typically employ lasers, plasma, ozone or other etching methods to etch the electrode surface, achieving satisfactory surface roughness and adding required surface functional groups to improve adsorption performance and electrochemical activity. [20][21][22] As shown in Fig. 2 (a) and (b), we modified the glassy carbon electrode (GCE) with nitrogen plasma and laser, and obtained the required oxygen-containing functional groups and nitrogen functional groups, then successfully detected ciprofloxacin (CFX) and ofloxacin (OFL).…”

A variety of organic and inorganic pollutants in water environments pose threats to human health. Therefore, it is critical to develop effective techniques to determine and monitor levels of water contamination. Compared with traditional detection methods, electrochemical sensors have the advantages of high sensitivity, low detection limits, and good selectivity. In this review, we summarize the progress made from 2000 to 2020 regarding the development of electrochemical sensors capable of detecting typical pollutants in different water environments. Since the concentrations of typical organic contaminants (antibiotics and pesticides) in water environments are often very low (generally at the nmol level), further improvements to electrode sensitivity and detection limit will be necessary. We also found that more detailed cost analysis of electrode materials is needed to support for future production and applications. When we apply the electrode to detect the real water samples, the anti-interference and electrochemical sensor componentization need further enhanced. Besides, although groundwater serves as the main or only source of drinking water in many areas, current studies on the electrochemical detection of groundwater pollutants are limited. We hope that this review will provide new ideas for the future development of electrochemical water contaminant sensors.

“…The spiking recoveries were from 88.2% to 107.5% with the RSDs from 8.2% to 12.5%, indicating good reliability of the present analytical protocol. Several studies were performed for OFL determination, such as spectrofluorimetry, colorimetry, electrochemistry, photoelectrochemical methods, and SERS [41][42][43][44][45][46]. The selectivity, linear range, LOD, and regeneration method of every detection method are listed in Table 2.…”

To this day, the preparation of surface-enhanced Raman spectroscopy (SERS) substrates with high sensitivity, selectivity, and stability has been the bottleneck to realizing SERS-based quantitative analysis in practical applications. In this paper, a thermo-sensitive imprinting SERS substrate material (TM@TiO2@Ag) is developed with a uniform structure and morphology, a controllable “hot spot” and photocatalytic regeneration. The as-prepared TM@TiO2@Ag nanocomposite is characterized by scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, dynamic light scattering, ultraviolet–visible (UV-Vis) spectroscopy, etc. After the effects of its thermo-sensitive property on localized surface plasmon resonance (LSPR) and SERS signals are investigated, this nanomaterial is used as the Raman-enhanced substrate for rapid and trace detection of ofloxacin (OFL) in water. It is found that, with the aid of unique structure and composition, temperature sensitivity, and molecule imprinting, the SERS sensor possesses considerably strong anti-interference ability not only to structure-unlike but also to structure-like co-existing substances, extremely low detectable concentration of 1.1 × 10−11 M for OFL at 1397 cm−1, as well as excellent reusability due to its photocatalytic degradation to target analytes.
