Summary: The electrospinning of polymer nanofibers, especially biodegradable cellulose acetate (CA) nanofibers, has attracted significant attention due to their unique properties and a wide range of applications. However, the conventional electrospinning process involves the use of toxic solvents and additives. In this study, we developed a green solvent system and used biosurfactants to improve the electrospinning process and obtain uniform and porous CA nanofibers. The nanofiber diameter and porous texture could be adjusted by tuning the solvent ratio, and the resulting nanofibers showed tunable degradation properties.

Summary: Cellulose and its derivatives are commonly used as nanofibrous biomaterials, but research on obtaining 3D cellulose nanofibers is limited. This study presents a simple method for converting electrospun 3D cellulose acetate/lactic acid nanofibers into a 3D cellulose/calcium lactate nanocomposite matrix, resulting in a stronger and more cell-friendly material suitable for bone tissue engineering. The successful conversion was verified through various analytical techniques, and the scaffolds were found to provide a suitable environment for cell growth and infiltration.

Summary: Rapid global industrialization has exacerbated the contamination of heavy metals in aquatic ecosystems. In this study, green, ultrafine cellulose-based porous nanofibrous membranes were developed for efficient removal of heavy metals by incorporating chitosan and using electrospinning techniques. The conventional electrospinning method resulted in a more uniform distribution of chemically active sites, leading to improved adsorption performance and reduced surface shrinkage during adsorption. The 30% CS conventional nanofibrous membranes exhibited the highest adsorption capacity for copper ions at a solution pH of 5.

Summary: Adsorptive-photocatalytic electrospun nanofiber membranes have shown great potential in wastewater treatment. However, their mechanical properties limit their use in pressure-driven filtration. In this study, dual-layered MoS2/PAN-CA membranes were successfully fabricated using electrospinning and hot-pressing techniques, resulting in improved physicochemical and structural properties. The MoS2/PAN-CA membranes exhibit promising performance in treating various pollutants in water and wastewater.

Summary: This study addressed the insufficient mechanical strength of natural hydrogel scaffolds in bone tissue engineering by incorporating regenerated cellulose nanofibers into chitosan hydrogel. The resulting rCL/CS composite scaffold showed improved compressive strength, biomineralization, and pre-osteoblast cell viability. The enhanced osteogenic differentiation ability of rCL/CS composite scaffold suggests its promise as a three-dimensional bio-scaffold for bone tissue engineering.

Summary: This study evaluated nanofibrous membranes based on polymeric blends of carboxymethyl-cellulose/silver-nanoparticle (CMC-AgNP) composite and polyvinyl alcohol (PVA) as suitable scaffolds for tissue engineering applications. The mean diameter of the nanofibers decreased as the weight content of CMC-AgNP in the polymeric blends increased. The interaction between CMC and PVA molecules, as well as the variation in nanofiber diameter, modified the mechanical properties of the membranes and prevented bacterial proliferation.

Summary: This research aimed to develop a bioactive wound dressing by combining herbal medicine and tissue engineering principles. The results of in vitro and in vivo studies showed that cellulose acetate scaffolds loaded with Lawsonia inermis extract (LIE) had the highest wound healing potential. These dressings promoted epithelial thickness, collagen deposition, and angiogenesis, while reducing inflammation and upregulating pro-healing genes.

Summary: Electrospinning is a promising method for fabricating bioengineered scaffolds, utilizing various types of biopolymers and flexible structures to achieve diverse output properties. By altering input variables, scaffolds with different mechanical and morphological properties can be fabricated. In this study, gelatin was blended with cellulose acetate to enhance the mechanical characteristics of electrospun scaffolds, with changes in concentration, weight ratio, and mandrel rotation speed affecting the properties achieved. The response surface method was used to model the continuous variation of Young's modulus, yield stress, and strain at rupture, providing engineers with a tool to adjust parameters for desired mechanical and structural properties.

Summary: Deacetylated cellulose acetate/thermoplastic polyurethane@graphene oxide nanofibrous membranes were prepared and characterized. The results showed that the introduction of graphene oxide significantly enhanced the adsorption capacity of the composite membranes for methylene blue and chromium (Cr (VI)). The Langmuir isotherm and second-order kinetic models were consistent with the adsorption mechanism of the composite membrane. The DA/TPU@GO composite nanofiber membrane exhibited excellent adsorption capacity and had potential applications in sewage treatment.
