“…Nevertheless, the significant discharge of Ni 2+ from several industries including electroplating, power plants, nickel-cadmium battery, rubber, and plastic industries leads to environmental pollution, thus causing Ni 2+ induced carcinogenicity, genotoxicity, immunotoxicity and effects in other vital organs including lung [122][123][124]. An early study used a dimethylglyoxime (DMG)/poly(caprolactone) (PCL) blend for the fabrication of optical sensors through electrospinning [125]. Firstly, the DMG has been dissolved with PCL in a mixture of DMF and dichloromethane (DCM) (50/50, v/v); then, the precursor solution was subjected to the electrospunning process.…”

“…The sensing experiments were performed by placing 3 × 3 cm 2 electrospun fiber mats in the Ni 2+ solution for a period of 10 min, and then the color change was observed. The corresponding results showed a significant color change due to the formation of a red-pink complex of Ni 2+ and DMG with a detection limit of 1 ppm [125]. In another similar example, DMG and PCL composite nanofibers have been collected on a glass slide and further impregnated with a polyvinyl alcohol (PVA) to make them transparent prior to spectroscopy analysis [126].…”

The increasing heavy metal pollution in the aquatic ecosystem mainly driven by industrial activities has raised severe concerns over human and environmental health that apparently necessitate the design and development of ideal strategies for the effective monitoring of heavy metals. In this regard, colorimetric detection provides excellent opportunities for the easy monitoring of heavy metal ions, and especially, corresponding solid-state sensors enable potential opportunities for their applicability in real-world monitoring. As a result of the significant interest originating from their simplicity, exceptional characteristics, and applicability, the electrospun nanofiber-based colorimetric detection of heavy metal ions has undergone radical developments in the recent decade. This review illustrates the range of various approaches and functional molecules employed in the fabrication of electrospun nanofibers intended for the colorimetric detection of various metal ions in water. We highlight relevant investigations on the fabrication of functionalized electrospun nanofibers encompassing different approaches and functional molecules along with their sensing performance. Furthermore, we discuss upcoming prospectus and future opportunities in the exploration of designing electrospun nanofiber-based colorimetric sensors for real-world applications.

“…However, further optimization of the sensitivity is definitely necessary in order to be competitive with other sensors based on other support materials. Also sensors for Ni 2+ have been produced by Dubas et al and Sereshti et al by doping of dimethylglyoxime in respectively poly(ε‐caprolactone) and polycaprolactam/polyvinylalcohol nanofibers. The resulting red color is due to the formation of a complex between two dimethylglyoxime molecules and nickel.…”

Sensors play a major role in many applications today, ranging from biomedicine to safety equipment, where they detect and warn us about changes in the environment. Nanofibers, characterized by high porosity, flexibility, and a large specific surface area, are the ideal material for ultrasensitive, fastresponding, and user-friendly sensor design. Indeed, a large specific surface area increases the sensitivity and response time of the sensor as the contact area with the analyte is enlarged. Thanks to the flexibility of membranes, nanofibrous sensors cannot only be applied in high-end analyte detection, but also in personal, daily use. Many different nanofibrous sensors have already been designed; albeit, the most straightforward and easiest-to-interpret sensor response is a visual change in color, which is of particular interest in the case of warning signals. Recently, many researchers have focused on the design of so-called colorimetric nanofibers, which typically involve the incorporation of a colorimetric functionality into the nanofibrous matrix. Many different strategies have been used and explored for colorimetric nanofibrous sensor design, which are outlined in this feature article. The many examples and applications demonstrate the value of colorimetric nanofibers for advanced optical sensor design, and could provide directions for future research in this area.

“…Poltue and co-workers [109] served the electrospun dimethylglyoxime/poly(caprolactone) (DMG/PCL) blend nanofibers as an optical sensor for the Ni(II) detection based on the formation of red Ni(DMG) 2 complex. It is reported that the as-spun sensors could be used to detect Ni(II) in the concentration of 1 ppm with a good linear response between 1 and 10 ppm.…”

Monitoring of usable, explosive, and hazardous materials (gases, heavy metal ions, and organic contaminants) is one of the most important concerns that has attracted growing attention in the past few decades. Numerous sensors have been developed to meet the demands and the pursuit of highly sensitive, selective, reversible, fast response and recovery, cost-effective, and portable sensors which have gained great interest. Electrospun nanofibrous membranes that possess large surface area, high porosity, good interconnected porous structure, and flexibility of surface functionalization are expected to be ideal candidates of substrates to improve the performance of the sensors. More interestingly, the novel two-dimensional nanofiber/net membranes fabricated by electrospinning/netting are demonstrated to have extremely large surface area and unique pore structure, which could further enhance the sensitivity, stability, and response speed of the sensors. In this chapter, we summarize recent progress in the development of electrospun nanofiber-based sensors, describe the design of different types of sensors, and discuss their sensing performances in detail. This chapter might bring further development and evolution of sensors based on electrospun nanofibers for the detection of various analytes.
