“…There is a wide interest in using synthetic polymers owing to their extraordinarily mechanical properties, controlled degradation rates and economic efficiency [2,3]. Polyacrylonitrile (PAN) is an important engineering polymer material which is commonly used in agriculture, textiles, filtration, protective materials and pharmaceuticals due to its good thermal properties, chemical resistance and superior mechanical characteristic [4].…”

Nowadays, bone repair by means of stem cells potential is considered as a new approach in regenerative medicine. Adipose-derived mesenchymal stem cells (AD-MSCs) have been investigated as a plentiful cell source with the ability of osteogenic differentiation which can play an important role in bone tissue engineering applications. Discovering proper elements in combination of scaffolds structure to stimulate osteogenesis in adipose-derived stem cells is one of the major concerns in this issue. Porous polymeric scaffolds such as polyacrylonitrile (PAN) and susceptible nanoparticles have attracted a lot of attention recently due to biodegradability and differentiation potential respectively. In the present study, clay-PAN nanocomposite (CPN) and graphene-PAN scaffold have been electrospuned separately and evaluated from the point of the osteogenic potential in AD-MSCs. The objective of this study was to determine the effect of clay and graphene nanoparticles with PAN nanofibers on the fate of viability and osteogenesis of AD-MSCs. First, isolated mesenchymal cells were characterized by flow cytometry. After cell culture on the surface of scaffolds MTT assay, scanning electron microscope (SEM) and DAPI staining were done. The scaffolds were characterized and osteogenic differentiation potential of AD-MSCs has been investigated. The results have indicated that alkaline phosphatase (ALP) activity, calcium content and collagen expression of cells which cultured on clay-PAN nanofibers were higher than cells which cultured on graphene-PAN scaffold. Taken together, these results suggest that porous nanofiber clay-PAN scaffold can enhance the osteogenic differentiation of AD-MSCs, and can be used as a new biodegradable scaffold for bone tissue engineering applications.

“…Moreover, the peaks at 2929 cm À1 and 1461 cm À1 were attributed to the stretching vibrations of the C-H bonds and bending vibrations of the C-H 2 bonds. 34 In the FTIR spectrum of the PSA/PAN/PSA nanobrous membranes, all the typical peaks of PSA and PAN were clearly recognized, which indicated that the nanocomposites PSA/PAN/PSA were successfully obtained.…”

“…In this respect, CuNPs and AgNPs may add a clear benefit when embedded in electrospun PAN and cellulose fibers. Additionally, in this case, the blending approach is the most investigated; silver and copper salts [103][104][105], or preformed ZnO-CuO-NPs [106], are included in the electrospinning solution. An interesting alternative is represented by the cellulose nanofibers, because the high number of -OH groups offers a location for fibers functionalization, thus regulating the nanophases upload and their release.…”

“…Table 1 reports a summary with some representative studies dealing with electrospun antimicrobial fibers embedding metal nanoparticles. [107] No matter the preparation method, all the above mentioned composite electrospun nanofibers have been proved to exert good antibacterial properties against many Gram-positive [70,92,97,99,[102][103][104][105][106][107][108]113,114] and Gram-negative [70,92,97,99,102,103,[105][106][107][108]113,114] species, as well as antifungal effect [70,[108][109][110]. The detailed analysis on the antibacterial mechanisms involved and the overview on the different antimicrobial tests is beyond the aim of this review; nevertheless, the readers interested in the topic can refer to [115][116][117][118][119][120].…”

Electrospinning is a versatile, simple, and low cost process for the controlled production of fibers. In recent years, its application to the development of multifunctional materials has encountered increasing success. In this paper, we briefly overview the general aspects of electrospinning and then we focus on the implementation of inorganic nanoantimicrobials, e.g., nanosized antimicrobial agents in electrospun fibers. The most relevant characteristics sought in nanoantimicrobials supported on (or dispersed into) polymeric materials are concisely discussed as well. The interesting literature issued in the last decade in the field of antimicrobial electrospun nanomaterials is critically described. A classification of the most relevant studies as a function of the different approaches chosen for incorporating nanoantimicrobials in the final material is also provided.
