Nanofiber Membranes Transformed Into 3D Scaffolds

Researchers combined gas foaming and 3D molding technologies to quickly transform electrospun membranes into complex 3D shapes for biomedical applications. The new approach demonstrates significant improvements in speed and quality compared with other methods, and is the first successful demonstration of formation of 3D neural tissue constructs with an ordered structure through differentiation of human neural progenitor/stem cells on these transformed 3D nanofiber scaffolds. They discuss their work in this week’s Applied Physics Reviews.

Creating Miracles with Polymeric Fibers

Mohan Edirisinghe leads a team at University College London studying the fabrication of polymeric nanofibers and microfibers — very thin fibers made up of polymers. The fibers can be woven into textilelike structures but depending on the use, different fiber thicknesses may be necessary. To study the effects of various parameters on fiber fabrication, the researchers compared the characteristics of fibers created in different ways. The group describes the work in Applied Physics Reviews.
