“…The formation of hydrogen bonds between bee pollen and SA/PVA causes improvement in the compactness and regularity of polymer chains. The thermal properties of the polymeric material depend on the mobility and compactness of the polymer chains and their crystalline structure in the material [ 49 , 50 ]. A minor change was observed in the melting temperature.…”

Green electrospun materials are gaining popularity in the quest for a more sustainable environment for human life. Bee pollen (BP) is a valuable apitherapeutic product and has many beneficial features such as antioxidant and antibacterial properties. Alginate is a natural and low-cost polymer. Both natural materials show good compatibility with human tissues for biomedical applications and have no toxic effect on the environment. In this study, bee pollen-loaded sodium alginate and polyvinyl alcohol (SA/PVA) nanofibrous mats were fabricated by the electrospinning technique. The green electrospun nanofibrous mats were analyzed by scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and differential scanning calorimeter (DSC). According to the findings of the study, the toxin-free electrospinning method is suitable for producing green nanomaterial. Because of the useful properties of the bee pollen and the favorable biocompatibility of the alginate fibers, the bee pollen-loaded SA/PVA electrospun mats have the potential for use in a variety of biomedical applications.

“…High voltage is applied to a polymer solution and the sample collector to produce electric field jets supporting the formation of fibers through solvent evaporation during the process [222,223]. The use of the technique focuses on the main discussions intrinsically connected with the area; it is interpreted as an innovative, effective technique with low cost and versatility that can be applied in several industrial fields [220,[224][225][226]. The electrified nanofibers have attracted the attention of enzyme engineering and biocatalysis, being considered a potential tool because of their numerous advantages: high surface area, multiple fixation points to the support, high porosity, interconnectivity, high thermal resistance, pH stability, and several solvents [216,220,222,223,227].…”

“…Electrofused nanofibers have a great potential to overcome dispersion problems, mass transfer limitation, and low recyclability and can be used as suitable supports for the immobilization of several enzymes [216,218,221]. In summary, the notoriety attributed to electrification as an innovative technique is directly connected with the qualification of nanofibers [220,225,227,230]. Aspects such as the diversity of polymers that can be electrophile, high porosity, and chemical interaction of the electrophile support give them a minimal impediment to mass transfer in addition to their industrial usability [216,219,223,225,230].…”

However, each enzyme interacts differently with the support, so when this technique is chosen, one should pay particular attention to the physical characteristics of the enzyme and the support, always looking at the congruence and adequacy of the size of the enzyme and the pore of the support [216,219,220,223,227,230].…”

“…Figure 5 shows how the process of enzyme immobilization by electrospinning occurs. Several studies have reported different proposals to immobilize enzymes in electrophile nanofibers [216,219,[223][224][225][226][227][228]. These proposals mainly include binding the enzyme on the surface of nanofibers and enzyme encapsulation [216,219,223,228].…”

The market for industrial enzymes has witnessed constant growth, which is currently around 7% a year, projected to reach $10.5 billion in 2024. Lipases are hydrolase enzymes naturally responsible for triglyceride hydrolysis. They are the most expansively used industrial biocatalysts, with wide application in a broad range of industries. However, these biocatalytic processes are usually limited by the low stability of the enzyme, the half-life time, and the processes required to solve these problems are complex and lack application feasibility at the industrial scale. Emerging technologies create new materials for enzyme carriers and sophisticate the well-known immobilization principles to produce more robust, eco-friendlier, and cheaper biocatalysts. Therefore, this review discusses the trending studies and industrial applications of the materials and protocols for lipase immobilization, analyzing their advantages and disadvantages. Finally, it summarizes the current challenges and potential alternatives for lipases at the industrial level.

Packaging is a growing field of interest, and the use of nanotechnology is accelerating its expansion. The study reports the fabrication of poly(vinyl alcohol) (PVA) blended sodium alginate (SA) and incorporated with different ratios of histidine‐capped silver (H‐AgNPs) nanoparticle films. Fabrication of PVA/SA/H‐AgNPs films was confirmed with the surface plasmon resonance (SPR) band denoted AgNPs presence between 400 and 420 nm measured by UV–Vis absorption spectroscopy. The characteristics of the polymeric biocomposite films were significantly altered by different ratios of AgNPs. The interaction of PVA/SA and PVA/SA with AgNPs was analyzed by using FT‐IR analysis. The degree of crystallinity was increased upon increasing the concentration of H‐AgNPs as confirmed by XRD measurements. The homogeneity of dispersion and surface morphology of samples were studied by FESEM. The addition of H‐AgNPs in the polymeric film increased the surface roughness of the polymeric film confirmed by AFM analysis. The contact angle of the PVA/SA blend matrix was observed to be 46.97°, and with the incorporation of AgNPs ranging from 3%, 5%, and 7% to the blend matrix, the contact angle of the nanocomposite films in increasing hydrophobic order was 60.53°, 83.57°, and 96.20°, respectively. The incorporation of AgNPs also demonstrates that the PVA/SA blend matrix has desirable thermal stability. The improved qualities were due to H bonding between PVA, SA, and H‐AgNPs, in which molecules contact strongly with one another. Furthermore, the PVA/SA/H‐AgNPs showed significant antibacterial activity against both Gram‐positive (G+) strains (Staphylococcus aureus) and Gram‐negative (G−) strains (Escherichia coli) bacterial infections. The findings of this research indicate that the PVA/SA/H‐AgNPs fabricated composite films considerable for applications in food packaging.
