Electrospinning of Gelatin Nanofiber for biomedical Application

Patterning of polymer nanofiber meshes by electrospinning for biomedical applications

The end-product of the electrospinning process is typically a randomly aligned fiber mesh or membrane. This is a result of the electric field generated between the drop of polymer solution at the needle and the collector. The developed electric field causes the stretching of the fibers and their random deposition. By judicious selection of the collector architecture, it is thus possible to deve...

Electrospinning of Continuous Nanofiber Bundles and Twisted Nanofiber Yarns

Spinning is a prehistoric technology in which endless filaments, shorter fibers or twisted fibers are put together to produce yarns that serve as key element to assemble multifarious structural designs for diverse functions. Electrospinning has been regarded as the most effective and versatile technology to produce nanofibers with controlled fiber morphology, dimension and functional components...

Biomedical Applications of Antibacterial Nanofiber Mats Made of Electrospinning with Wire Electrodes

Twisted stainless steel wires are used as wire electrodes for electrospinning the polyvinyl alcohol (PVA)/zinc citrate nanofiber mats. The morphology and diameter of the nanofibers in PVA/zinc citrate nanofiber mats are evaluated. We measured the antibacterial efficacy against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) of the nanofiber mats. We also examined the cell adhes...

Microscale electrospinning of polymer nanofiber interconnections

Electrospinning and stabilization of chitosan nanofiber mats

Chitosan is of special interest for biotechnological and medical applications due to its antibacterial, antifungal and other intrinsic physical and chemical properties. The biopolymer can, e.g., be used for biotechnological purposes, as a filter medium, in medical products, etc. In all these applications, the inner surface should be maximized to increase the contact area with the filtered mediu...
