Electrospun nanofibers based on plant extract bioactive materials as functional additives: possible sources and prospective applications

Abstract

Electrospun nanofibers based on plant extracts have garnered increasing interest as valuable bioactive materials for medicinal and packaging applications. This concise review examines recent studies on functional plant extract nanofibers, emphasizing their fabrication techniques, antimicrobial characteristics, and potential applications. Plant extracts having bioactive compounds are generally obtained from diverse natural sources that can be incorporated into electrospinning solutions to develop functional nanofibers with enhanced germicidal activities. Key findings suggest that nanofibers integrated with natural bioactive materials possess adequate antibacterial, antioxidant, anti-inflammatory, and anticancer properties and are considered expedient biocompatible materials for use in biomedical and food packaging. The potential biomedical applications of these nanofibers include wound healing, drug delivery, and tissue engineering owing to their germicidal activity, biodegradability and biocompatibility, while packaging applications leverage antibacterial and food preservation capabilities. However, some constraints, including insolubility of some extracts, insufficient mechanical robustness for electrospinning, and lack of green solvents to mitigate bio-toxicity, have hindered their diversified applications. The current review, therefore, summarizes future research avenues concerning the scope of overcoming the limitations in this burgeoning field. Overall, plant extract functional nanofibers demonstrate their potential for utilization in biomedical and food packaging applications, but more research is needed to scale up production and make these eco-friendly biocomposite materials commercially available.
