“…The high voltage applied at the spinneret tip is used as the viscous electrospinning solution in the spinneret and is extruded at a steady rate to be charged. A polymer solution’s hemispherical surface is stretched into a cone, which is called a Taylor cone [ 7 , 8 ], when the applied voltage rises. The electrostatic force defeats the droplet’s surface tension once the voltage is sufficiently high.…”

Electrospun porous nanofibers have gained a lot of interest recently in various fields because of their adjustable porous structure, high specific surface area, and large number of active sites, which can further enhance the performance of materials. This paper provides an overview of the common polymers, preparation, and applications of electrospun porous nanofibers. Firstly, the polymers commonly used to construct porous structures and the main pore-forming methods in porous nanofibers by electrospinning, namely the template method and phase separation method, are introduced. Secondly, recent applications of electrospun porous nanofibers in air purification, water treatment, energy storage, biomedicine, food packaging, sensor, sound and wave absorption, flame retardant, and heat insulation are reviewed. Finally, the challenges and possible research directions for the future study of electrospun porous nanofibers are discussed.

“…These properties can support cell synthesis of specific proteins and other biochemical and biological processes required for healthy tissue growth [28,83]. Therefore, electrospun fibers have become excellent candidates for various applications, such as catalysis [84], filtration [85], water treatment [86][87][88][89], biosensors [90][91][92], food packaging [93,94], cosmetics [95] and biomedicine [96][97][98][99][100][101].…”

Herbal medicine has a long history of medical efficacy with low toxicity, side effects and good biocompatibility. However, the bioavailability of the extract of raw herbs and bioactive compounds is poor because of their low water solubility. In order to overcome the solubility issues, electrospinning technology can offer a delivery alternative to resolve them. The electrospun fibers have the advantages of high specific surface area, high porosity, excellent mechanical strength and flexible structures. At the same time, various natural and synthetic polymer-bound fibers can mimic extracellular matrix applications in different medical fields. In this paper, the development of electrospinning technology and polymers used for incorporating herbal medicine into electrospun nanofibers are reviewed. Finally, the recent progress of the applications of these herbal medicine nanofibers in biomedical (drug delivery, wound dressing, tissue engineering) and food fields along with their future prospects is discussed.

“…The development of DDS also stimulates the development of raw material selection and the introduction of advanced techniques as pharmaceutical methods ( Feng and Hao, 2021 ). Electrospinning is one of the powerful methods for continuous production of drug loaded nanofibers ( Xue et al, 2019 ; Liu et al, 2022a ; Sivan et al, 2022b ; Cao et al, 2022 ; Han et al, 2022 ; Lv et al, 2022 ), and electrospun nanofibers have been demonstrated their potential applications in almost all kinds of scientific fields such as energy, environment, medical and food ( Pang et al, 2021 ; Jiang et al, 2022a ; Li et al, 2022a ; Bai et al, 2022 ; Xu et al, 2022 ; Yu et al, 2023 ). As a top-down technology, electrospinning is famous for its simplicity, efficiency and flexibility in direct preparation of nanofibers ( Du et al, 2022 ; Huang et al, 2022 ; Yao et al, 2022 ).…”

The poor solubility of numerous drugs pose a long-existing challenge to the researchers in the fields of pharmaceutics, bioengineering and biotechnology. Many “top-down” and “bottom-up” nano fabrication methods have been exploited to provide solutions for this issue. In this study, a combination strategy of top-down process (electrospinning) and bottom-up (self-emulsifying) was demonstrated to be useful for enhancing the dissolution of a typical poorly water-soluble anticancer model drug (paclitaxel, PTX). With polyvinylpyrrolidone (PVP K90) as the filament-forming matrix and drug carrier, polyoxyethylene castor oil (PCO) as emulsifier, and triglyceride (TG) as oil phase, Both a single-fluid blending process and a coaxial process were utilized to prepare medicated nanofibers. Scanning electron microscope and transmission electron microscope (TEM) results clearly demonstrated the morphology and inner structures of the nanofibers. The lipid nanoparticles of emulsions after self-emulsification were also assessed through TEM. The encapsulation efficiency (EE) and in vitro dissolution tests demonstrated that the cores-shell nanofibers could provide a better self-emulsifying process int terms of a higher EE and a better drug sustained release profile. Meanwhile, an increase of sheath fluid rate could benefit an even better results, suggesting a clear process-property-performance relationship. The protocols reported here pave anew way for effective oral delivery of poorly water-soluble drug.
