“…The TG-containing scaffolds have a more hydrophilic nature as understood from lower contact angles than the PVA/β-S sample. It is found that the PVA/β-S/TG hybrid fibers have a contact angle between PVA and PVA/β-S. Because of their higher hydrophilicity and water-solubility, the TG-containing samples have a lower contact angle than PVA/β-S scaffold due to the TG water-soluble fraction [5,20]. It is noted that the PVA/β-S/TG 0.5% sample is regarded as more hydrophilic than PVA/β-S/TG 1%, representing the optimally fabricated sample in view of hydrophilicity.…”

“…This method allows one to better connect the cathodic side of a polarized electrode to a reservoir [17]. The ability to use electrospinning on natural and synthetic polymers offers a wide range of biomedical applications [17,18], such as drug delivery, tissue engineering, and wound dressing [3,5,19,20]. Electrospinning is a one-of-a-kind technique that allows sufficiently nanoscale biomaterials to be designed and adjusted for enhanced differentiation, proliferation, and cell migration at the injured site, as well as tissue regeneration post-treatment [21].…”

Electrospun polyvinyl alcohol (PVA) and tragacanth gum (TG) were used to develop nanofibrous scaffolds containing poorly water-soluble β-Sitosterol (β-S). Different concentrations and ratios of the polymeric composite including β-S (10% w v−1) in PVA (8% w v−1) combined with TG (0.5 and 1% w v−1) were prepared and electrospun. The synthesis method includes four electrospinning parameters of solution concentration, feeding rate, voltage, and distance of the collector to the tip of the needle, which are independently optimized to achieve uniform nanofibers with a desirable mean diameter for cell culture. The collected nanofibers were characterized by SEM, FTIR, and XRD measurements. A contact angle measurement described the hydrophilicity of the scaffold. MTT test was carried out on the obtained nanofibers containing L929 normal fibroblast cells. The mechanical strength, porosity, and deterioration of the scaffolds were well discussed. The mean nanofiber diameters ranged from 63 ± 20 nm to 97 ± 46 nm. The nanofibers loaded with β-S were freely soluble in water and displayed a remarkable biocompatible nature. The cultured cells illustrated sheet-like stretched growth morphology and penetrated the nanofibrous pores of the PVA/β-S/TG scaffolds. The dissolution was related to submicron-level recrystallization of β-S with sufficient conditions for culturing L929 cells. It was concluded that electrospinning is a promising technique for poorly water-soluble β-S formulations that could be used in biomedical applications.

Nanobiotechnology was considered as unique branch of contemporary science that facilitates paradigm shift in the field of material research. This study utilizes easy, convenient and cost-effective essential oil isolated from the onion seed as reducing agent for fabrication of copper nanoparticles and applicability of synthesized nanoparticles as supercapacitor electrodes. In the synthesis process, solution colour turned from pale blue to green and then it reach reddish brown colour due to reduction in Cu2+ in copper sulphate in to Cu0 nanoparticles that exhibit characteristic wavelength maxima of 292 nm on UV-visible spectrophotometer. The GCMS analysis confirms the involvement of 2-phenylethanol, 1-hexanol, α-phellandrene, 2-pentylfuran, palmitic acid and trimethylbenzene from essential oil in the formation of nanoparticles. The particles were in spherical shape with most abundant particle size of ~ 17 nm having monoclinic phase crystal structure with 80.95% copper content. The supercapacitor application of the synthesized nanoparticles was investigated through electrochemical investigation. The specific conductance of synthesized nanoparticles was assessed through cyclic voltammetry that exhibit an impressive response of 364, 332, 311, 255 and 206 F/g, respectively at 10, 20, 40, 60 and 100 mV/s. The specific capacitance of nanoparticles was confirmed as 364 F/g with 97.1% retention capacity after 6000 cycles. The findings indicate that copper oxide nanoparticles, obtained biologically, exhibit promising applicability with well-suitability for use in the energy storage devices. Overall, the results of the current study show that the biologically produced copper oxide nanoparticles have intriguing uses as supercapacitor electrodes.

Tree peony (Paeonia suffruticosa Andr.) is a popular cut flower among ornamental plants. However, its short vase life severely hinders the production and application of cut tree peony flowers. To extend the postharvest longevity and improve the horticultural value, silver nanoparticles (Ag-NPs) was applied for reducing bacterial proliferation and xylem blockage in cut tree peony flowers in vitro and in vivo. Ag-NPs was synthesized with the leaf extract of Eucommia ulmoides and characterized. The Ag-NPs aqueous solution showed inhibitory activity against bacterial populations isolated from stem ends of cut tree peony ‘Luoyang Hong’ in vitro. The minimum inhibitory concentration (MIC) was 10 mg L−1. Compared with the control, pretreatments with Ag-NPs aqueous solution at 5 and 10 mg L−1 for 24 h increased flower diameter, relative fresh weight (RFW), and water balance of tree peony ‘Luoyang Hong’ flowers. Additionally, malondialdehyde (MDA) and H2O2 content in pretreated petals were lower than the control during the vase life. The activities of superoxide dismutase (SOD) and catalase (CAT) in pretreated petals were lower than that of the control at the early vase stage and higher at the late vase life. Furthermore, pretreatments with Ag-NPs aqueous solution at 10 mg L−1 for 24 h could reduce bacterial proliferation in the xylem vessels on the stem ends by confocal laser scanning microscope (CLSM) and scanning electron microscope (SEM). Overall, pretreatments with green synthesized Ag-NPs aqueous solution effectively reduced bacteria-induced xylem blockage of cut tree peony, resulting in improved water uptake, extended vase life, and enhanced postharvest quality. Therefore, this technique can be used as a promising postharvest technology in the cut flower industry.
