“…PLA fiber has low cell viability due to the absence of antimicrobial agents. Wu et al [28] prepared the polylactic acid (PLA)/tea polyphenol (TP) nanofiber membranes using coaxial electrospinning. In their work, the 6 wt% PLA/TP membrane with the best antibacterial properties had an inhibitory circle width of 1.45 mm against S. aureus and 1.20 mm for E. coli, which is lower than PLA/5-Cl8Q and PLA/CTAB/5-Cl8Q.…”

With the continuous application of antibacterial materials, various problems have emerged, such as expensive prices and the potential development of resistance. Cationic antibacterial agents, due to their high solubility, reactivity, and antibacterial properties, are considered as environmentally friendly and cost-effective antibacterial agents. In addition, the electrospinning technique is recognized as a versatile and high-efficiency method to produce nanofibers with multifunctional properties and adjustable structures. In this work, we prepared a series of nanofiber membranes by electrospinning technology using hexadecyl trimethyl ammonium Bromide (CTAB) and 5-Chloro-8-hydroxyquinoline (5-Cl8Q) as antibacterial agents and polylactic acid (PLA) as substrate. The antimicrobial performance of PLA/CTAB/5-Cl8Q was the highest among the prepared materials, which inhabited S. aureus and E. coli up to 99.9% and 95.9%, respectively, and the antibacterial properties were stable. In general, PLA/CTAB/5-Cl8Q has great development potential, and it can be applied to real life as a cost-effective, biodegradable and highly antibacterial material.

“…Thus, they are able to target the drug in situ, thereby increasing their activity and minimizing their toxicity [38]. There are different types of compounds that can be incorporated into electrospun/electrosprayed structures to be delivered [39]. In fact, antitumor agents, antibiotics, ribonucleic acid, deoxyribonucleic acid, and proteins can be encapsulated by different biodegradable and biocompatible solutions that act as coating materials in electrohydrodynamic techniques.…”

Extracts from plants have been one of the main sources of antioxidants, namely polyphenols. The associated drawbacks, such as instability against environmental factors, low bioavailability, and loss of activity, must be considered during microencapsulation for a better application. Electrohydrodynamic processes have been investigated as promising tools to fabricate crucial vectors to minimize these limitations. The developed microstructures present high potential to encapsulate active compounds and for controlling their release. The fabricated electrospun/electrosprayed structures present different benefits when compared with structures developed by other techniques; they present a high surface-area-to-volume ratio as well as porosity, great materials handling, and scalable production—among other advantages—which make them able to be widely applied in different fields, namely in the food industry. This review presents a summary of the electrohydrodynamic processes, main studies, and their application.

“…Firstly, utilizing a renewable biomass source as the monomer improves the overall sustainability. Additionally, the tunable biodegradation reduces long-term toxicity issues [25][26][27][28][29][30][31][32][33][34][35][36][37]. For biomedical applications, PLAs have been utilized as bioresorbable implants, sutures, and tissue engineering scaffolds.…”

Green electrospinning harnesses the potential of renewable biomaterials to craft biodegradable nanofiber structures, expanding their utility across a spectrum of applications. In this comprehensive review, we summarize the production, characterization and application of electrospun cellulose, collagen, gelatin and other biopolymer nanofibers in tissue engineering, drug delivery, biosensing, environmental remediation, agriculture and synthetic biology. These applications span diverse fields, including tissue engineering, drug delivery, biosensing, environmental remediation, agriculture, and synthetic biology. In the realm of tissue engineering, nanofibers emerge as key players, adept at mimicking the intricacies of the extracellular matrix. These fibers serve as scaffolds and vascular grafts, showcasing their potential to regenerate and repair tissues. Moreover, they facilitate controlled drug and gene delivery, ensuring sustained therapeutic levels essential for optimized wound healing and cancer treatment. Biosensing platforms, another prominent arena, leverage nanofibers by immobilizing enzymes and antibodies onto their surfaces. This enables precise glucose monitoring, pathogen detection, and immunodiagnostics. In the environmental sector, these fibers prove invaluable, purifying water through efficient adsorption and filtration, while also serving as potent air filtration agents against pollutants and pathogens. Agricultural applications see the deployment of nanofibers in controlled release fertilizers and pesticides, enhancing crop management, and extending antimicrobial food packaging coatings to prolong shelf life. In the realm of synthetic biology, these fibers play a pivotal role by encapsulating cells and facilitating bacteria-mediated prodrug activation strategies. Across this multifaceted landscape, nanofibers offer tunable topographies and surface functionalities that tightly regulate cellular behavior and molecular interactions. Importantly, their biodegradable nature aligns with sustainability goals, positioning them as promising alternatives to synthetic polymer-based technologies. As research and development continue to refine and expand the capabilities of green electrospun nanofibers, their versatility promises to advance numerous applications in the realms of biomedicine and biotechnology, contributing to a more sustainable and environmentally conscious future.
