The production of nanofibrous membranes finds high interest in the biomedical field, from drug delivery to wound dressing. types polymers used for these applications are mainly synthetic and natural biopolymers that have different properties, especially terms bioactivity, adhesion cells, mechanical properties. In current study, two processes, namely uniaxial electrospinning coaxial configuratio...

Electrospun nanofibres are highly attractive products taking advantage of their remarkable specific surface area, high porosity and good transport properties that are ideal requirements for efficient molecule detection. In this work, fibres of polyacrylonitrile (PAN) were first prepared by electrospinning. These fibres were then coated with silver nanoparticles or silver/graphene nanocomposites...

Membrane filtration has become an accepted technology for the removal of pathogens from drinking water. Viruses, known to contaminate water supplies, are too small to be removed by a size-exclusion mechanism without a large energy penalty. Thus, functionalized electrospun membranes that can adsorb viruses have drawn our interest. We chose a quaternized chitosan derivative (HTCC) which carries a...

Dextran is a versatile biomacromolecule for preparing electrospun nanofibrous membranes by blending with either water-soluble bioactive agents or hydrophobic biodegradable polymers for biomedical applications. In this study, an antibacterial electrospun scaffold was prepared by electrospinning of a solution composed of dextran, polyurethane (PU) and ciprofloxacin HCl (CipHCl) drug. The obtained...

OBJECTIVE Due to the capacity of the amniotic membrane (Am) to support re-epithelisation and inhibit scar formation, Am has a potential to become a considerable asset for reconstructive urology i.e., reconstruction of ureters and urethrae. The application of Am in reconstructive urology is limited due to a poor mechanical characteristic. Am reinforcement with electrospun nanofibers offers a new...
