“…The electrospun zein nanofibers are shaped like a ribbon and are several hundreds of nanometers in diameter, which is consistent with the results previously published in the Torres-Giner report. 21 Figure 1(a) and 1(b) show that the average diameters of the electrospun unloaded and CLZNFs fabricated without Tween 80 are ~543±248 nm and ~668±216 nm, respectively, indicating that incorporating curcumin into the zein nanofibers could increase their average diameter. This is Released curcumin t=t Actual amount of curcumin t=0 reported.…”

“…Zein is the major storage protein of corn, which comprises about 45-50% of its protein content. 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.…”

“…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.

“…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.

“…In addition, Torres-Giner et al, 2008a also developed porous electrospun chitosan nanofibers using pure trichloromethane solvent. Recently, electrospun chitosan composite nanofibrous mats have been fabricated using synthetic biodegradable polymers such as PVA (Miya et al, 1994;Zheng et al, 2001), poly(ethylene oxide) (PEO) (Yilmaz et al, 2003), poly(vinyl pyrrolidine) (PVP) (Ignatova et al, 2007), poly(lactic acid) (PLA) (Peesan et al, 2006;Torres-Giner et al, 2008b) and poly(ethylene terpthalate (PET) (Jung et al, 2007). These composite fiber mats have more advantageous over the electrospinning of pure chitosan.…”

Chitin and its deacetylated derivative, chitosan, are non-toxic, biodegradable biopolymers currently being developed for use in biomedical applications such as tissue engineering scaffolds, wound dressings, separation membranes, antibacterial coatings, stent coatings, and sensors. Recently, nano fibrous scaffolds based on chitin or chitosan have potential applications in tissue engineering. Tissue engineering is one of the most exciting interdisciplinary and multidisciplinary research areas today, and there has been exponential growth in the number of research publications in this area in recent years. It involves the use of living cells, manipulated through their extracellular environment or genetically to develop biological substitutes for implantation into the body and/or to foster remodeling of tissues in some active manners. Electrospun chitin and chitosan nano fibrous scaffolds would be used to produce tissue engineering scaffolds with improved cytocompatibility, which could mimic the native extracellular matrix (ECM). Electrospinning is truly a feasible means of producing nano fibrous scaffolds that resemble the ECM, however, moreover than this, it is imperative that the effects of an artificial matrix has on cell growth, proliferation, and differentiation. This review summarizes the recent progress in chitin and chitosan based nano fibrous scaffolds with an emphasis in tissue engineering applications.
