Electrospun multi‐chamber core–shell nanofibers and their controlled release behaviors: A review

Abstract

AbstractCore–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
