“…By this approach, we can obtain noninvasive, high-resolution images that provide information on the morphology of the nanofibers in three dimensions with no need of sample treatment. The last aspect is relevant since techniques generally used for morphological characterization of nanofibers are often based on electron microscopy, atomic force microscopy, and fluorescence confocal microscopy following labeling of samples with exogenous fluorescent probes. , Although very useful, these methods often require invasive and time-consuming sample preparation prior to analysis. As shown in Figure C and in Figure S1, POTATO-72% nanofibers formed a less dense network as compared to PEA-72% and SOY-72% nanofibers at the same nominal contents of protein isolate.…”

Plant protein-based nanofibers generated by eco-friendly waterborne electrospinning are emerging as sustainable and innovative materials with vast applications in different biomedical areas. In this study, we fabricated electrospun nanofibers based on potato, pea, and soy protein isolates, achieving remarkably high protein content without the use of organic solvents, strong bases, or surfactants. The different protein nanofibers were characterized by means of quantitative fluorescence imaging, optical spectroscopy, and dynamic mechanical analysis. Results indicated that the intrinsic nature of the proteins modulated the properties of the nanofibers in terms of morphology, fluorescence fingerprints, mechanical strength, and stability in aqueous environments. Pea and soy protein isolates, both rich in β-structure, led to the formation of robust and dense nanofibers, which slowly disintegrated in water. On the contrary, less dense and highly soluble nanofibers were generated from the structurally more flexible potato protein isolate, and these nanofibers demonstrated lower resistance to breakage. Our findings indicate the importance of protein structural elements when designing protein-based electrospun nanofibers with specific features. Deciphering the intricate relationship between protein structure at the molecular level and properties of nanofiber holds promise for the development of biomaterials with enhanced efficacy in diverse biomedical applications.

“…It is important to mention that the addition of the functionalized clay (i.e., intercalated Fe‐MMT) did not compromise the structural integrity of the composite product. It is known that, beyond a critical loading volume, clay can agglomerate and create inhomogeneous mechanical properties in the fiber (Ji et al, 2006; Roodbar Shojaei et al, 2019). It is believed that the Fe‐MMT would form highly aligned layered structures inside the fibers as the clay reorients with the stretched polymer during the electrospinning process.…”

This study presents a bench‐scale study on the dynamic removal of arsenic from wastewater by an adsorption membrane consisting of a polycaprolactone matrix with iron‐intercalated montmorillonite filler. A 2K factorial design of experiment was employed to study the effect of different adsorption parameters; namely, flow rate, initial influent concentration, and thickness of adsorbent sheets on breakthrough time. Longer breakthrough times were associated with low flow rates, low initial influent concentrations, and thick nanofiber membrane. The bed depth service time (BDST) approach was used to model adsorption kinetics. An empirical equation for predicting service time of the adsorbent membrane was obtained and was used to design the bench‐scale column. The performance of the adsorption column was accurately predicted by the BDST model. This practical, nanocomposite‐based adsorption column offers a promising alternative wastewater treatment for addressing arsenic contamination in water.

“…As the charges increases in polymer solution it leads higher elongation force to jet from needle tip and induce thinner fibers [58]. It is well known that NF diameters can be affected many parameters such as molecular weight, viscosity, polarity, surface tension, surface free energy or conductivity, also electrospinning setup [59]. In this work, we did not examine these parameters after and before blending copolymer, which may be considered as the missing part of this study and beyond our main focus.…”

Nanofibers (NF) and nanoparticles are attractive in the field of drug delivery especially to improve the drug bioavailability and administration. Easy manipulation of polymeric fibers as macroscopic bulk material may give rise to potential uses as implantable local drug delivery platforms. In this study, poly(ethylene glycol) polyethyleneimine (mPEG: PEI) copolymer blended poly ε-caprolactone (PCL) nanofibers, NFblend accommodating mesoporous silica nanoparticles (MSN) as the implantable local drug delivery system was achieved by employing spin coating and cold atmospheric plasma (CAP) post-processing. The morphology and wettability, mechanical properties, and in vitro cytocompatibility features of NFblend ensured its features as a potential implantable local drug delivery system. The electron microscopy images affirmed the macropores on NFblend are still accessible and claimed the random nanofiber alignment of the NFblend after MSN accommodation may promote cell attachments. Furthermore, the drug release profile from the NFblend and in vitro cytocompatibility and scaffolding features for cell attachment were determined. The sustained drug release profile for 48h was provided regardless of MSN impairment from mat and bulk degradation. The accumulation of curcumin loaded MSN (MSN@Cur) onto NFblend by CAP-assisted spin coating promote cell proliferation compared to its non-treated counterparts. All in all, the obtained NFblend-MSN@Cur nanofiber mats have a high potential to be employed as an implantable local drug delivery system.
