Electrospinning for the Modification of 3D Objects for the Potential Use in Tissue Engineering

Abstract

Electrospinning is often investigated for biotechnological applications, such as tissue engineering and cell growth in general. In many cases, three-dimensional scaffolds would be advantageous to prepare tissues in a desired shape. Some studies thus investigated 3D-printed scaffolds decorated with electrospun nanofibers. Here, we report on the influence of 3D-printed substrates on fiber orientation and diameter of a nanofiber mat, directly electrospun on conductive and isolating 3D-printed objects, and show the effect of shadowing, taking 3D-printed ears with electrospun nanofiber mats as an example for potential and direct application in tissue engineering in general.

Electrospinning of Magnetite–Polyacrylonitrile Composites for the Production of Oxygen Reduction Reaction Catalysts

“…The advantage of using electrospinning does not lie only in obtaining nanosized fibers with controllable composition but also in the possibility of tuning the microstructure of the material by smart choice of the solution and spinning conditions. Roughly divided, there are two basic electrospinning processes, namely the needle-based electrospinning process and the needle-free electrospinning process [13]. The components of needle-free electrospinning are an upper wire, a lower wire, a carriage containing a polymer solution and a substrate for collecting the nanofibers, which are generated in a high-voltage field.…”

Study on Filtration Performance of PVDF/PUL Composite Air Filtration Membrane Based on Far-Field Electrospinning

“…With the continuous development in recent years, electrospinning has gradually become an important part of the nanofabrication process. Nanofiber membranes produced by electrospinning have been used in various fields, such as drug delivery [9][10][11], wound healing [12][13][14], filtration and separation [15,16], tissue engineering [17][18][19], textiles [20,21] with food packing [22,23], sensors [24], battery separators [25] and so on. In terms of filtration application, the electrospinning fiber air filter membrane can be regarded as working in the stable filtration stage [26].…”
