Electrospinning of nanofibers from non-polymeric systems is rather challenging, yet in this study, we have successfully performed electrospinning of nanofibers from two of the native cyclodextrins (CDs); α-CD and β-CD. Electrospinning was carried out for highly concentrated solutions of α-CD (120% up to 160%, w/v) and β-CD (120% up to 150%, w/v) in basic aqueous system. At optimal concentration...

High voltage power was used to produce jet in electrospinning. It was very difficult to study electrospinning jets by experiment, because they have high-speed and complex movements in the high-voltage electrostatic field, and the diameter of jet was very small. In this study, the software of finite element analysis was used to simulate the formation process of a stable jet in electrospinning. T...

BACKGROUND The objective of this investigation was to develop a new class of antibacterial material in the form of nanofibers coated with silver nanoparticles (AgNPs) using a modified coaxial electrospinning approach. Through manipulation of the distribution on the surface of nanofibers, the antibacterial effect of Ag can be improved substantially. METHODS Using polyacrylonitrile (PAN) as the...

Electrospinning has emerged as an attractive technique for the fabrication of ultrafine fibres in micro-/nano-scale fineness: however, it remains a significant technological challenge to assemble aligned fibre arrays via an conventional electrospinning method due to the inherent whipping instability of the polymeric jet. We herein have first developed a simple modified electrospinning method wi...

Tissue engineering is a technique by which a live tissue can be re-constructed and one of its main goals is to associate cells with biomaterials. Electrospinning is a technique that facilitates the production of nanofibers and is commonly used to develop fibrous scaffolds to be used in tissue engineering. In the present study, a different approach for cell incorporation into fibrous scaffolds w...

Based on the natural sequence of Araneus diadematus Fibroin 4 (ADF4), the recombinant spider silk protein eADF4(C16) has been engineered. This highly repetitive protein has a molecular weight of 48kDa and is soluble in different solvents (hexafluoroisopropanol (HFIP), formic acid and aqueous buffers). eADF4(C16) provides a high potential for various technical applications when processed into mo...

Electrospinning or electrostatic fiber spinning is an emerging technology that requires electric fields for the formation of non-woven materials that can be used in clothing, highperformance filters, separation membranes, scaffolds in tissue engineering, reinforcement in composite materials, templates for the preparation of functional nanotubes, and many others applications [1]. Polycaprolacton...

Poly(vinyl alcohol) (PVA) nanofibres were obtained by electrospinning of PVA/water solutions. Formation of beaded fibres combined with decreased fibre diameters was observed for low PVA concentrations. Electrospinning of blends of PVA of different molecular weight resulted in less bead formation and smaller fibre diameters as compared to corresponding homopolymers of similar viscosity.

Cubic (Im3[combining macron]m) mesoporous silica nanofibers were successfully prepared using a new F127-PVA-SiO2 tri-constituent assembly approach by the electrospinning technique. PVA was used to protect the F127 directed cubic micelles which usually deform during electrospinning. The preformed Au NPs can be loaded inside the mesopores of the nanofibers.
