“…This has resulted in numerous companies manufacturing nanofibers for different applications, including car filters, facial masks, and water filters. In addition, the size of the resulting fibers and the possibility of controllable structures have seen their applications in biomedical applications with a few being clinically approved [13]. Nonetheless, over the past decades, there have been significant advancements and modifications on the conventional laboratory-scale electrospinning technique (single-needle electrospinning), leading to the attainment of a high production rate, desired patterns, and morphologies [20,24].…”

“…Alginate is composed of 1-4-linked β-d-mannuronic and α-l-guluronic acid residues, and it is obtained from the cell walls of brown algae (e.g., Laminaria and Ascophyllum species) [13,25]. Alginate, also known as alginic acid or algin, is a linear polysaccharide with the monomeric acid residues being covalently linked together in different compositions and sequences.…”

“…It is a linear copolymer composed of β-d-mannurate (M) and α-l-guluronate, which are linked through the 1-4 glycosidic bonds. It was first isolated from brown algae in 1880; however, its commercial production only began in the 20th century [8,12,13]. The properties of alginate directly depend on the sequence and composition of the M/G units.…”

Alginate has been a material of choice for a spectrum of applications, ranging from metal adsorption to wound dressing. Electrospinning has added a new dimension to polymeric materials, including alginate, which can be processed to their nanosize levels in order to afford unique nanostructured materials with fascinating properties. The resulting nanostructured materials often feature high porosity, stability, permeability, and a large surface-to-volume ratio. In the present review, recent trends on electrospun alginate nanofibers from over the past 10 years toward advanced applications are discussed. The application of electrospun alginate nanofibers in various fields such as bioremediation, scaffolds for skin tissue engineering, drug delivery, and sensors are also elucidated.

“…They have experienced the outstanding effects of TiO 2 NPs [ 131 , 132 , 133 , 134 ], Ag NPs [ 135 , 136 , 137 ], and GO [ 138 , 139 , 140 ], which had given PNC membranes hydrophilic properties, but they are eager to develop more economical materials at a time when mass production is imminent. Of course, small-scale studies of lab scale introduced by less expensive nanoparticles—such as ZnO [ 141 , 142 ], CaCO 3 [ 143 , 144 ], zeolite [ 80 , 145 ], and HNTs [ 57 , 146 ]—are being conducted in this regard. Without steady excavation of additional materials following these studies, growth in the membrane market, which has been shown so far by the stimuli-responsive PNC material, is bound to be limited.…”

Although water, air, and other resources are abundant on earth, they have been subjected to strict environmental regulations. This is because of their limitation of availability for human consumption. In the separation industry, the membrane system was introduced to increase the amount of resources available to mankind. Experts used an easy-to-use polymeric material to design several membranes with porous structures for wastewater treatment, gas separation, and chemical removal; consequently, they succeeded in obtaining positive results. However, past polymeric membranes exhibited a chronic drawback such that it was difficult to simultaneously augment the permeate flux and improve its selectivity toward certain substances. Because of the trade-off relationship that existed between permeability and selectivity, the membrane efficiency was not very good; consequently, the cost-effectiveness was significantly hindered because there was no other alternative than to replace the membrane in order to maintain its initial characteristics steadily. This review begins with the introduction of a polymer nanocomposite (PNC) membrane that has been designed to solve the chronic problem of polymeric membranes; subsequently, the stimuli-responsive PNC membrane is elucidated, which has established itself as a popular topic among researchers in the separation industry for several decades. Furthermore, we have listed the different types and examples of stimuli-responsive PNC membranes, which can be switched by external stimuli, while discussing the future direction of the membrane separation industry.

along with other polysaccharides (e.g., celluloses, chitosan, etc.), is indeed considered an extremely promising material in the viewpoint of circular economy and in substituting petroleum-derived polymers. [3] Among others, one of the reasons for alginate success is its unique capability to bind different cations leading to stable and tailor-made hydrogels. [4] Owing to its biocompatibility, biodegradability, and nontoxicity, in the past decades alginate has been vastly explored for drug and gene delivery, tissue engineering, and wound healing applications. [5] In this sense, the recent nanotechnological advances have allowed the fabrication and exploitation of alginate-based nanostructured materials with completely new capabilities. Thereby, it is not surprising that nowadays a broad variety of alginate-based nanomaterials with various shapes, sizes, and compositions are prepared via different approaches, including controlled gelation, electrospinning and electrospraying, self-assembly, phase-separation, and micro fluidics., All these nanostructures hold the potential to interact with living organisms much more efficiently with respect to bulk systems, hence leading to specific functionalities at the same time avoiding the occurrence of toxicity issues. [6][7][8] Despite the use of alginate-based nanomaterials has been reviewed in the past, the focus has been commonly pointed to their generic properties and applications. Conversely, this review attempts to provide a more specific and comprehensive summary limited to the most recent advances in the fabrication and use of two of the most common and promising alginatebased nanomaterials, namely nanoparticles (NPs) and electrospun nanofibers (NFs), with a focus on biomedical and pharmaceutical applications.
