“…With the increase of the amount of sorghum extract, splashing of the nanofibers was increased and they started forming branched nanofibers that were connected with others (Figures 5c and 5d). The modified physical properties that developed in zein/sorghum extract solutions are responsible for these morphological changes [32]. An opposite trend was observed in case of zein/Poria cocos nanofibers as the fiber diameters expanded slightly with the increase of the amount of Poria cocos extract.…”

“…As a biocompatible and biodegradable protein, zein has useful applications in tissue engineering and drug delivery [8,[23][24][25][26]. Also, zein has been extensively used in food packaging, cosmetic, pharmaceutical and biomedical industries [24,[27][28][29][30][31][32]. Another useful plant protein sorghum (Sorghum bicolor L. Moench) is an important cereal food crop and in Asia and Africa, it is considered as an important human food resource [33].…”

Zein produced from maize is a hydrophobic protein, which holds great potential for a number of industrial applications, for example, food packaging, pharmaceutical, cosmetic, and biomedical industry. Sorghum, known as important cereal crop worldwide, is a good source of various phytochemicals such as tannins, phenolic acids, anthocyanins, phytosterols, and policosanols, and these phytochemicals have great impact on human health. Poria cocos, a well-known traditional East-Asian medicinal plant, is found around the roots of pine trees in Korea and China. As a rapid and efficient process, electrospinning has drawn huge interest among scientists to produce nanostructured polymer materials with excellent properties. In this work, we studied the influence of co-solvent ratio and concentration of zein/medicinal plant extract on the morphologies of nanostructured zein/medicinal plant extract nanomaterials prepared by electrospinning technique from ethanol/water solution. The zein/medicinal extract nanofibers were characterized by field-emission scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and differential scanning calorimetric technique. And we were to incorporate medicinal plant resources into the electro-spun zein nanofibers by electrospinning technique to investigate the effect of medicinal extract on the morphologies, antibacterial, antioxidant, and other properties. Zein/medicinal plant extract might have a practical use as a new preservative for cosmeceutical applications.

Abstract. Over the past decades, electrospinning of biopolymers down to nanoscale garnered much interest to address most of the millennia issues related to water treatment. The fabrication of these nanostructured membranes added a new dimension to the current nanotechnologies where a wide range of materials can be processed to their nanosize. Electrospinning is a simple and versatile technique to fabricate unique nanostructured membranes with fascinating properties for a wide spectrum of applications such as filtration and others. These nanostructured membranes, fabricated by electrospinning, were found to be of a paramount importance because of their advanced inherited properties such as large surface-to-volume ratio, as well as tuneable porosity, stability, and high permeability. The extensive research conducted on these materials extended the success of electrospinning not only to bio-based polymer nanofibres, but to their hybrids and their derivatives. The technique also created avenues for advanced and massive production of nanofibres. This paper reviews the recent developments in the electrospinning technique. Electrospinning of biopolymers, their blends and functionalization using metals/metal oxides, and the potential applications of electrospun nanofibrous membranes in water filtration are discussed.

“…21 It is one of the most hydrophobic proteins because its main constituents are proline and glutamine, which are apolar amino acids. 22 Besides, zein can be dissolved in aqueous polar organic solvents such as nontoxic aqueous ethanol. Because of its solubility and abundance, zein has been widely used as a coating/excipient for foods and drugs.…”

“…Electrospun nonwoven zein mats have previously been investigated for application as novel scaffolds and drug carriers. [21][22][23] Recently, J.-M. Yang et al produced zein nanofiber with poor water soluble drug, ferulic acid (FA), via core-shell electrospinning and found that the FA release 100% from composite zein nanofibers in 14 h. 24 Brahatheeswaran et al 25 have incorporated curcumin into a zein nanofiber mats by using trifluoroethanol. They found that curcumin incorporated into zein matrix can maintain its biological activity and sustain its release.…”

Electrospinning was used to load curcumin (a natural compound that has antiinflammatory properties) into zein nanofibers. An emulsifier, Tween 80, was combined with curcumin in the zein nanofibers. The morphology of the curcumin-loaded zein nanofibers (CLZNFs) was observed using field emission scanning electron microscopy. Investigation of curcumin released from the zein nanofibers into phosphate buffer saline at pH 7 indicated that the Tween 80 had increased the amount of curcumin released from the CLZNFs. The antibacterial activity of the CLZNFs against Staphylococcus aureus (S. aureus) was determined by measuring the optical density of bacterial solutions containing CLZNFs. The zein nanofibers fabricated with 10 wt% surfactant and 1.6 wt% curcumin showed high (i.e., 83%) efficiency in inhibiting the growth of S. aureus in the solution incubated for 21 h. These results suggest that the electrospun CLZNFs show potential application as antibacterial nonwoven mats.
