Drug eluting electrospun scaffolds for tissue regeneration
The desired healing response to electrospun scaffolds in tissue engineering is often limited by poor ingrowth due to insufficient porosity, thrombogenicity, lack of vascularisation and/or excessive inflammation. This study aimed at increasing structural porosity and incorporating/delivering …

Tunability of Electrospun Scaffolds for Tissue Engineering
… fiber diameter for cell adhesion. However, electrospun scaffolds lack large pores between fibers and result in a densely packed mesh in which cells can adhere only to the surface of the material. Control of scaffold fiber size and porosity is critical to ensure scaffolds have a fiber …

High strength carbon nanofibers derived from electrospun polyacrylonitrile
Carbon nanofibers (CNFs) derived from polyacrylonitrile (PAN) have not yet demonstrated the high tensile strength and Young’s modulus of their microscale counterparts. This is due to the current lack of understanding of the effect of electrospinning conditions on the quality of PAN precursor …

Application of electrospun fiber membranes in water purification
Electrospun membranes are attractive for the liquid filtration applications especially as microfiltration membranes because they are low in solidity and have open, highly interconnected porous structures. Nevertheless, liquid filtration processes are pressure driven; hence, it is crucial to …

Electrospun Blends of Polydioxanone and Fibrinogen for Urological Applications
The need for tissue and organ replacements cannot be satisfied by autograft and allografts alone. The purpose of this study was to investigate the feasibility of electrospinning a blend of polydioxanone and fibrinogen to produce an engineered tissue scaffold. Fiber diameter and pore size of blends …

Coaxially electrospun heparin-eluting scaffolds for vascular graft application
The use of electrospun scaffolds for small diameter vascular grafts (< 6 mm) has shown promise in the search for alternative solutions, as current synthetic grafts have high failure rates. The inclusion of heparin into such scaffolds can be beneficial for vascular graft applications as it could …
