“…The electrospinning process is inexpensive, facile, and versatile for producing submicron scale fibers, which has been used extensively in many studies and applications [18][19][20][21][22][23][24][25][26][27]. Various florescent electrospun (ES) polymer nanofiber-based chemosensors in our previous studies were designed for sensing pH [28][29][30][31][32], temperature [33][34][35], and NO gas [36].…”

“…Notably, some studies have reported fluorescent ES nanofiber-based chemosensors for sensing specific HTMs such as Fe 3+ [29], Hg 2+ [28,31,32,35,37], Zn 2+ [30,37], and Cu 2+ [31,37]. We previously reported a novel fluorescent chemosensory ES nanofibrous membrane with high selectivity and reversibility toward pH-and Hg 2+ , which was prepared using poly(hydroxyethyl-co-N-methylolacrylamide-co-rhodamine derivative) copolymers.…”

“…We previously reported a novel fluorescent chemosensory ES nanofibrous membrane with high selectivity and reversibility toward pH-and Hg 2+ , which was prepared using poly(hydroxyethyl-co-N-methylolacrylamide-co-rhodamine derivative) copolymers. In addition, the high surface-to-volume ratio for ES nanofibers affords them with higher sensitivity relative to that of thin films [28]. Moreover, ES nanofibers with thermo-responsive properties have attracted considerable attention because their morphology and diameter can be effectively tuned using environmental temperature, and thus they can be used in many applications such as new types of chemosensors and drug carriers [38][39][40].…”

“…which were recorded using a Fluorolog-3 spectrofluorometer (Horiba Jobin Yvon). All PL spectra of ES Nanofiber for pH and Hg 2+ sensing were recorded using the Fluorolog-3 spectrofluorometer and excited at a wavelength of 540 nm, as described in Supporting Information, which is similar to that in our previous studies [28][29][30][31][32][33][34][35][36][37].…”

Novel multifunctional fluorescent chemosensors composed of electrospun (ES) nanofibers with high sensitivity toward pH, mercury ions (Hg2+), and temperature were prepared from poly(N-Isopropylacrylamide-co-N-methylolacrylamide-co-rhodamine derivative) (poly(NIPAAm-co-NMA-co-RhBN2AM)) by employing electrospinning process. NIPAAm and NMA moieties provide hydrophilic and thermo-responsive properties (absorption of Hg2+ in aqueous solutions), and chemical cross-linking sites (stabilization of the fibrous structure in aqueous solutions), respectively. The fluorescent probe, RhBN2AM is highly sensitive toward pH and Hg2+. Synthesis of poly(NIPAAm-co-NMA-co-RhBN2AM) with different compositions were carried on via free-radical polymerization. ES nanofibers prepared from sensory copolymers with a 71.1:28.4:0.5 NIPAAm: NMA: RhBN2AM ratio (P3 ES nanofibers) exhibited significant color change from nonfluorescent to red fluorescence while sensing pH or Hg2+, and high reversibility of on/off switchable fluorescence emission when Hg2+ and ethylenediaminetetraacetic acid (EDTA) were sequentially added. The P3 ES nanofibrous membranes had a higher surface-to-volume ratio to enhance their performance than did the corresponding thin films. In addition, the fluorescence emission of P3 ES nanofibrous membranes exhibited second enhancement above the lower critical solution temperature. Thus, the ES nanofibrous membranes prepared from P3 with on/off switchable capacity and thermo-responsive characteristics can be used as multifunctional sensory devise for specific heavy transition metal (HTM) in aqueous solutions.

Since the last decade, electrospinning is garnering more attention in the scientific research community, industries, applications like sensing (glucose, H 2 O 2 , dopamine, ascorbic acid, uric acid, neurotransmitter, etc.), biomedical applications (wound dressing, wound healing, skin, nerve, bone tissue engineering, and drug delivery systems), water treatment, energy harvesting, and storage applications. This review paper provides a brief overview of the electrospinning method, history of the electrospinning, factors affecting the electrospun nanofibers, and their morphology with different materials and composites (metals, metal oxides, 2D material, polymers and copolymers, carbon-based materials, etc.) used in the electrospinning technique with optical spinning parameters. Moreover, this paper deliberates the application of electrospun nanofibers and fibrous mats for sensing (electrochemical, optical, fluorescence, colorimetric, mechanical, photoelectric, mass sensitive change, resistive, ultrasensitive, etc.) in most illustrative representations. In the end, the challenges, opportunities of the electrospun nanofibers, and new direction for future progress are also discussed.
