“…The photoluminescence spectra of the TPN-Cl 2 -doped poly HEMA nanofibrous film showed that the introduction of Zn 2+ in the concentration range of 0-10 −6 M demonstrated that the emission peak at 620 nM was responsible for Zn 2+ , which becomes a shoulder, remains responsive, and is attributed to the formation of a complex between Zn and TPN-Cl 2 (see Figure 22). The sensing performance of the fibrous film has been noted with a detection limit of 10 −6 M, which is higher than the planar film [130].…”

“…Therefore, the colorimetric determination of Zn 2+ has also been attracted accountable interest; correspondingly, very few efforts have been directed toward the electrospun nanofiber-based colorimetric detection of Zn 2+ . For example, meso-2,6-dichlorophenyltripyrrinone (TPN-Cl 2 ), a red fluorescent probe sensitive to Zn 2+ has been doped into hydrogel polymer poly(2-hydroxyethyl methacrylate) (poly HEMA) and electrospun to obtain nanofibrous film that was further used for the detection of Zn 2+ in water [130]. A planar film has been also fabricated using similar composition for the purpose of comparing their sensing efficiency.…”

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.

Hg 2+ pollution in seafood, grain, and even drinking water especially in many industrial districts. [1][2][3][4] Therefore, it is of great urgency to develop facile and effective sensing apparatus to discriminate Hg 2+polluted food and water samples. For this purpose, a large amount of powerful electric, colorimetric, and fluorescent Hg 2+ chemosensors have been developed over the past decades. [5][6][7][8][9][10][11][12][13][14][15] Nevertheless, most of these Hg 2+ -sensing studies, despite state-of-the-art, are primarily based on solution phase. For practical infield applications, solid-state sensing materials are more attractive as they can provide operational simplicity, portability, and good stability. [16][17][18][19][20][21][22][23][24][25][26][27] Among various solid-state sensing materials, flexible fluorescent hydrogel films are attracting increasing attention in recent years. [28][29][30][31][32][33][34][35][36][37][38][39][40][41] This is because hydrogels are hydrophilic, water swellable polymer networks that can allow efficient diffusion of water-soluble pollutants into the hydrogel matrix. [42][43][44][45][46][47][48][49] Moreover, their chemical and physical properties could be finely tuned via proper molecular design in order to further enhance their binding affinity for targeted molecules. Therefore, these flexible hydrogel chemosensors can address the restricted detection sensitivity caused by hindered and slow diffusion of aqueous testing samples inside conventional hydrophobic, dense sensing films, thus generating higher In some industrial districts, abuse discharge of waste water has resulted in serious Hg 2+ pollution in seafood, grain, and even drinking water. In order to protect people from mercury(II)-polluted food and water, many solid-state fluorescent Hg 2+ -sensing materials are developed in terms of facile operation. However, one primary challenging issue is the restricted sensitivity caused by hindered slow diffusion of aqueous testing samples inside these conventional hydrophobic, dense, and rigid film materials. Herein, robust hydrophilic fluorescent hydrogel-coated flexible paper/textile film chemosensors are reported. Their design relies on a specific chemical reaction between Hg 2+ and the grafted thiourea moieties to induce remarkable "green-to-blue" emission color change. Thanks to their hierarchical porous structures fixed by interwoven paper/textile fibers, these flexible chemosensors allow fast capillary-force-driven mercury(II) diffusion into the hydrophilic hydrogel matrix, thus enabling visual detection of nearly nM-level Hg 2+ . On this basis, robust fluorescent hydrogel-coated wearable sensing gloves are fabricated for the first time, which significantly facilitate infield visual detection and effectively protect operators far from the toxic Hg 2+ -polluted samples. These developed flexible wearable sensing systems might not only hold great potential applications in mercury(II) detection, but also inspire the development of nextgeneration sensing apparatus for other...

“…This phenomenon is generally measured by Stern–Volmer plots and visualized by fluorescent microscopy. Many optical nanofibrous sensors for electron‐deficient compounds such as explosives and heavy metal ions have been designed based on this technique by either doping fluorescent compounds into the electrospinning solution, chemically modifying nanofibers, or “decorating” the surface of the nanofibers . Very often, these changes in fluorescence intensity can be seen with the naked eye or with the help of relatively simple equipment such as light emitting diode (LED) light sources, charge‐coulpled device (CCD) cameras or compact inexpensive spectrometers .…”

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.
