“…This will result in the electric force drawing a burst of polymer solution to the metal collector. The solvent will evaporate throughout this procedure, and the fiber network will gather in the collector 9 . In this study, a voltage of 12 kV and a tip‐to‐collector distance of 11 cm are the electrospinning process parameters used at room temperature.…”

“…The electrospinning method has many advantages, including cost-effectiveness, simplicity, great flexibility, and the ability to create micro and nanofibers using polymers. [7][8][9] Several studies have developed nanofiber as a carrier matrix for fertilizers or pesticides. The nanofiber matrix enables the fertilizer to be released into the planting medium over an extended period (slow release), hence the term slow-release fertilizer (SRF).…”

Nanofiber is a material used as a drug carrier matrix in drug release materials. Its morphology has high porosity and good flexibility, making it suitable for this purpose. The use of nanofiber as a carrier matrix in slow‐release fertilizer (SRF) material is expected to provide a solution for releasing fertilizer into the soil more measurably and efficiently In this study, PVA/Urea/TiO2 nanofibers were fabricated using the electrospinning method. PVA/Urea/TiO2 SRFs were prepared using varying urea mass percentages (10%, 15%, and 20% of PVA mass) and the concentration of titanium dioxide suspension solution (0, 0.2, and 0.4 mL). Every sample was analyzed using scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) and tested using contact angle and slow‐release tests. From SEM characterizations, all samples showed the ability to form nanofiber. It was found that the membrane diameter sizes for each sample A, B, C, D, E, and F were 341 ± 5, 309 ± 12, 109 ± 3, 313 ± 10, 109 ± 3, and 158 ± 6 nm, respectively. The FTIR characterizations showed that all the matrix samples successfully contained the nitrogen group, which was found at wave number 1605 cm−1 (NH deformation), 1574 cm−1 (CN stretching), and 3430 cm−1 (NH stretching). The SEM mapping images confirmed the presence of titanium dioxide (green dots). The contact angle test showed that all samples had hydrophilic properties (the contact angle value lower than 90°), and the greatest value of contact angle measurement was 31.08° for sample C/E (sample with the most presence of TiO2 suspension solution 0.4 mL). The sample with the greatest TiO2 suspension concentration (0.4 mL) had the longest urea release time, lasting 8 days. This result indicates the addition of TiO2, can potentially suppress the hydrophilic properties of the PVA membrane. It is found that the addition of TiO2 influenced the membrane's hydrophilicity, consequently increasing the release rate. This study used the Korsmeyer–Peppas mathematical kinetic model to show that diffusion and swelling are release mechanisms for SRF membranes.

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.

The practice of using a massive amount of environmental unfriendly and toxic petroleum-based materials in tissue engineering and biomedical fields demands the materials, which are biodegradable, renewable, environmentally friendly, biocompatible, and bioactive. So, renewable polymers have got considerable attention due to their numerous desirable properties. The nanofibers that are prepared from renewable materials and their blends can integrate the properties of both nanofibers and renewable polymers. Development of scaffolds that mimic the construction of tissues at nanoscale is a great challenge for tissue engineering. Electrospinning is the most promising technique for nanofibers formation. Nanofibers provide a platform for cell adhesion, proliferation, and differentiation. Therefore, nanofibers from sustainable materials have been used in tissue engineering and biomedical fields. In this review, methods for nanofibers fabrication, sustainable nanofibers made from natural and synthetic polymers and their applications in tissue engineering and biomedical field, have been emphasized.
