“…In the electrospinning (ES), an external electric field is applied to overcome the polymer solution surface tension and a charged jet is then ejected from the so-called Taylor cone at the tip of the spinning nozzle [1][2][3][4][5][6][7][8][9][10]. The technology has been known as an efficient and simple method for fabricating polymer nanofibers [11,12].…”

An electrospun composite fiber process is a multi-phase and multi-physics process. It was very difficult to study a charged jet in the electrospinning process for the fabrication of composite fibers by experiments. In this study, the liquid-solid two-phase flow in the electrospinning process for fabrication of composite fibers was researched numerically. The results showed the addition of conductive nanoparticles resulted in the increase of the jet flow velocity, and the decrease of the fiber?s diameter. The CFD results corresponded well with the experimental data.

“…The principle is that the electric current at a constant scan rate is recorded as the electrode potential varies over time between the two potential limits. The changes in the scanning rate produce corresponding results (Elgrishi et al, 2018;Chen et al, 2019;Vanýsek, 2019;Vilas-Boas et al, 2019;Wen et al, 2021). Amperometry is based on the Cottrell equation and defines the measurement of the current at a controlled applied potential as a function of time.…”

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.

“…A novel modified spinneret based on needleless technology called mushroom has been developed to increase the quality and yield of NF production by generating stable pre-Taylor cones with high curvature, resulting in the production rate of 13.7 g/h [ 86 ]. To increase the electric current, an auxiliary electrode can be introduced [ 17 , 87 ]. For instance, a modified spinneret consisting of a narrow, long gutter bounded by a metal electrode having a sharp edge has been developed for a continuous high production rate of NFs.…”

Recently, the electrospinning (ES) process has been extensively studied due to its potential applications in various fields, particularly pharmaceutical and biomedical purposes. The production rate using typical ES technology is usually around 0.01–1 g/h, which is lower than pharmaceutical industry production requirements. Therefore, different companies have worked to develop electrospinning equipment, technological solutions, and electrospun materials into large-scale production. Different approaches have been explored to scale-up the production mainly by increasing the nanofiber jet through multiple needles, free-surface technologies, and hybrid methods that use an additional energy source. Among them, needleless and centrifugal methods have gained the most attention and applications. Besides, the production rate reached (450 g/h in some cases) makes these methods feasible in the pharmaceutical industry. The present study overviews and compares the most recent ES approaches successfully developed for nanofibers’ large-scale production and accompanying challenges with some examples of applied approaches in drug delivery systems. Besides, various types of commercial products and devices released to the markets have been mentioned.
