“…Figure 3d exhibited the synthetic route of core–shell nanofibers, while the corresponding structures was observed in Figure 3e,f. Furthermore, dopamine could also be attached to the surface of fibers by self‐polymerization, and combined with β‐cyclodextrin through hydrogen bonding to form a composite shell layer, enhancing the adsorption capacity of dyes in water (Wang, Dong, et al, 2022). Figure 3g–j depicts the relationship between the thickness of the shell layer and dopamine concentration.…”

Core–shell structure is a concentric circle structure found in nature. The rapid development of electrospinning technology provides more approaches for the production of core–shell nanofibers. The nanoscale effects and expansive specific surface area of core–shell nanofibers can facilitate the dissolution of drugs. By employing ingenious structural designs and judicious polymer selection, specialized nanofiber drug delivery systems can be prepared to achieve controlled drug release. The synergistic combination of core–shell structure and materials exhibits a strong strategy for enhancing the drug utilization efficiency and customizing the release profile of drugs. Consequently, multi‐chamber core–shell nanofibers hold great promise for highly efficient disease treatment. However, little attention concentration is focused on the effect of multi‐chamber core–shell nanofibers on controlled release of drugs. In this review, we introduced different fabrication techniques for multi‐chamber core–shell nanostructures, including advanced electrospinning technologies and surface functionalization. Subsequently, we reviewed the different controlled drug release behaviors of multi‐chamber core–shell nanofibers and their potential needs for disease treatment. The comprehensive elucidation of controlled release behaviors based on electrospun multi‐chamber core–shell nanostructures could inspire the exploration of novel controlled delivery systems. Furthermore, once these fibers with customizable drug release profiles move toward industrial mass production, they will potentially promote the development of pharmacy and the treatment of various diseases.This article is categorized under: Therapeutic Approaches and Drug Discovery > Emerging Technologies

“…This affinity improves the efficiency of dye adsorption. By increasing the number of functional groups (such as hydroxyl or carboxyl) [128,129], the prepared nanofiber membrane can absorb anionic and cationic dyes simultaneously, further expanding the practicality of the nanofiber membrane. According to the experiment of Fang-fang Ma et al [52], the prepared PVDF@PDA@PPY composite nanofiber membranes can adsorb not only cationic dyes and anionic dyes but also adsorb heavy metal chromium ions.…”

With the rapid development of nanotechnology, electrospun nanofiber membranes (ENM) application and preparation methods have attracted attention. With many advantages such as high specific surface area, obvious interconnected structure, and high porosity, ENM has been widely used in many fields, especially in water treatment, with more advantages. ENM solves the shortcomings of traditional means, such as low efficiency, high energy consumption, and difficulty in recycling, and it is suitable for recycling and treatment of industrial wastewater. This review begins with a description of electrospinning technology, describing the structure, preparation methods, and factors of common ENMs. At the same time, the removal of heavy metal ions and dyes by ENMs is introduced. The mechanism of ENM adsorption on heavy metal ions and dyes is chelation or electrostatic attraction, which has excellent adsorption and filtration ability for heavy metal ions and dyes, and the adsorption capacity of ENMs for heavy metal ions and dyes can be improved by increasing the metal chelation sites. Therefore, this technology and mechanism can be exploited to develop new, better, and more effective separation methods for the removal of harmful pollutants to cope with the gradually increasing water scarcity and pollution. Finally, it is hoped that this review will provide some guidance and direction for research on wastewater treatment and industrial production.

“…31 Recently, PDA and its derivatives have successfully been adopted to modify different types of nanofibers, such as cellulose nanofibrils (CNF) 32 and electrospun poly(vinylidene fluoride) fibers (PVDF). 33 The resulting PDAmodified nanofibers are well-dispersed and show excellent adsorption capacity for different pollutants in water. Therefore, we reason that conferring silk nanofibers with a uniform layer of PDA might be a facile means to produce well-dispersed PDA-modified silk nanofibers as advanced adsorbents to tackle water pollution caused by organic dyes.…”
