“…The polymers in electrospun can be divided into the following categories: natural polymer, synthetic polymer, conductive polymer, and molecular imprinted polymer ( Chakraborty et al, 2021a ; Kim et al, 2019a ). Most of the functional ingredients in electrospun nanofiber membranes are nanomaterials, which can serve both as substrates of enzymes and reaction mediators to improve the detection signal ( Chakraborty S et al, 2021 ; Yang et al, 2020 ). The nanomaterials used in electrospinning can be divided into the following categories: 0D NM, 1D NM, 2D NM, and 3D NM ( Gong et al, 2019 ; Wongkaew et al, 2019 ; Guo Qi et al, 2020 ; Sehit and Altintas, 2020 ).…”

Diabetes is a chronic, systemic metabolic disease that leads to multiple complications, even death. Meanwhile, the number of people with diabetes worldwide is increasing year by year. Sensors play an important role in the development of biomedical devices. The development of efficient, stable, and inexpensive glucose sensors for the continuous monitoring of blood glucose levels has received widespread attention because they can provide reliable data for diabetes prevention and diagnosis. Electrospun nanofibers are new kinds of functional nanocomposites that show incredible capabilities for high-level biosensing. This article reviews glucose sensors based on electrospun nanofibers. The principles of the glucose sensor, the types of glucose measurement, and the glucose detection methods are briefly discussed. The principle of electrospinning and its applications and advantages in glucose sensors are then introduced. This article provides a comprehensive summary of the applications and advantages of polymers and nanomaterials in electrospun nanofiber-based glucose sensors. The relevant applications and comparisons of enzymatic and non-enzymatic nanofiber-based glucose sensors are discussed in detail. The main advantages and disadvantages of glucose sensors based on electrospun nanofibers are evaluated, and some solutions are proposed. Finally, potential commercial development and improved methods for glucose sensors based on electrospinning nanofibers are discussed.

“…NW-based electrochemical biosensors have been developed to detect biological and chemical species (e.g. DNA, viruses, proteins, antibiotics and glucose) with high sensitivity and selectivity [198][199][200]. The voltammetric signals of electroactive species diffused from the bulk solution increase due to the high surface-to-volume ratios of NWs.…”

Realizing promising materials for use in next-generation devices at the nanoscale is of enormous importance from both fundamental and applied perspectives. Nonmagnetic and magnetic metal nanowire (NW) arrays fabricated by template-based electrodeposition (ED) techniques have long been considered as good candidates for this purpose. In this review, we focus on the fabrication techniques and characterizations of electrochemically deposited NWs with single, binary, ternary and multilayered component structures mostly carried out in our group. Particular attention is paid to the crystalline and magnetic characteristics (coercivity, squareness, magnetic phase, interactions and magnetization reversal modes) of NW arrays embedded in mild and hard anodized anodic aluminum oxide (AAO) templates with different pore diameters. The pulsed alternating current ED technique is proposed as a versatile approach in high-efficiency filling of the AAO templates, while also allowing for tuning magnetic properties of the resultant NWs. The first-order reversal curve analysis is also highlighted as an advanced characterization tool for nanomagnet arrays. Finally, potential cutting-edge nanoscale applications (magnetic information storage, energy storage and conversion, electronics, biosensing, microwave absorption and giant magnetoresistance) of magnetic NWs are presented.
