“…66 The two mechanisms of water passing through the membrane are (1) water penetrates the porous membranes and (2) water seeps into the membranes. As mentioned above, PVP is a water-soluble material; 67,68 thus, a high PVP content will increase the permeability of the membrane. Therefore, it was evident that the lowest WCA was found in ABSP5.…”

“…Another study found that due to the solubility of polyvinylpyrrolidone (PVP) and ethyl cellulose, the abovementioned homemade eccentric spinneret, which was built for applying side-by-side electrospinning, formed a nanofiber that could offer biphase drug release (EC). The redesigned spinneret's differently shaped nanofibers resulted in a faster burst release in the first phase and a slower sustained release in the second phase [28].…”

In the field of biomaterial research, the electrospinning device is now used to manufacture nanofibers that can be used to encapsulate whole microorganisms such as bacterial cells, funguses, viruses, and even spores. The nanofiber encapsulated cells will have greater significance in the coming future because of their wide variety of applications in various fields. Nanofibers act as microorganism reservoir systems that enhance their properties such as viability, controlled release of products, biomedical applications, and bioremediation. The effect of electrostatic forces on a droplet of liquid polymer or polymer solution is based on electrospinning. Electrospun nanofibers act as ideal native extracellular matrices for microorganisms and have also had a tremendous advantage in drug delivery systems where modern research is still underway. During electrospinning, nearly all microorganisms may be inserted into a polymer matrix that forms a composite nanofiber. The evolution in electrospinning technique over the past few decades has become promising. New ideas have been generated to enhance the techniques and improve the overall applications and properties of nanofibers. This technique has been transformed by the advent of the electrospinning machine. The electrospun nanofibers can be chemically characterized by a wide variety of procedures such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). Electrospinning has various applications, for example, in wastewater treatment, tissue engineering, food industry, drug delivery, agriculture, and cosmetics. Nanofiber encapsulation of microorganisms increased the shelf life of the microorganisms; the cells remain viable for months. It also helps in the control release of bacterial products. The present review demonstrates the role of nanofiber in the encapsulation of the whole cell.

Cellulose derivatives are obtained from renewable sources, making them an environmentally friendly option in many industrial applications. Manufacturing fine cellulose fibers is confronted with multifaceted challenges due to cellulose's intricate nature, such as its highly organized structure and hydrogen bonding chain. In this study, for the first time, fibers in the nanometer to micrometer scale diameter from cellulose derivatives were successfully produced without the assistance of polymer precursors using the pressurized gyration (PG) technique. The cellulose derivatives investigated in this work were ethyl cellulose (EC) and cellulose acetate (CA), representing the ether and ester cellulose derivatives, respectively. Electrospinning (ES) technique was also used to compare the fibers produced by this technique with those produced by PG. Both PG and nozzle-PG succeeded in producing EC-based fibers with diameters ranging from 488 to 825 nm, with a higher production rate than ES. In contrast, ES succeeded in producing bead-free fibers from EC and CA with a wide range of solvent systems and concentrations. Scanning electron microscopy was used to analyze the fiber morphology, diameter distribution, and alignment. Additionally, Fourier transform infrared spectroscopy, x-ray diffraction, and differential scanning calorimetry were used to compare the physicochemical nature of the fibers produced by PG and ES. These tests revealed that the fibers produced from the two spinning methods had identical physicochemical structures and properties. With further research and development efforts, PG has the potential to be a promising technique for producing cellulose derivative-based fibers with a high production rate, which could be employed for applications in drug delivery, tissue engineering, and wound dressing.
