“…Most of the water-resistant polymers need to be spun from toxic or corrosive solvents, while only some of them can also be electrospun from low-toxic solvents such as dimethyl sulfoxide (DMSO) [41]. The spinnability from DMSO is one of the reasons that polyacrylonitrile (PAN) is often used in electrospinning [16][17][18][42][43][44]. The possibility of using PAN as a precursor for carbon nanofibers is another reason why this material is often electrospun [45][46][47].…”

In biotechnology, the field of cell cultivation is highly relevant. Cultivated cells can be used, for example, for the development of biopharmaceuticals and in tissue engineering. Commonly, mammalian cells are grown in bioreactors, T-flasks, well plates, etc., without a specific substrate. Nanofibrous mats, however, have been reported to promote cell growth, adhesion, and proliferation. Here, we give an overview of the different attempts at cultivating mammalian cells on electrospun nanofiber mats for biotechnological and biomedical purposes. Starting with a brief overview of the different electrospinning methods, resulting in random or defined fiber orientations in the nanofiber mats, we describe the typical materials used in cell growth applications in biotechnology and tissue engineering. The influence of using different surface morphologies and polymers or polymer blends on the possible application of such nanofiber mats for tissue engineering and other biotechnological applications is discussed. Polymer blends, in particular, can often be used to reach the required combination of mechanical and biological properties, making such nanofiber mats highly suitable for tissue engineering and other biotechnological or biomedical cell growth applications.

“…Other polymers need toxic solvents, which makes a sophisticated post-treatment necessary to Technologies 2022, 10, 66 2 of 12 avoid reducing the biocompatibility of the nanofiber mats [17,18]. Only few water-stable polymers can be electrospun from the low-toxic solvent dimethyl sulfoxide (DMSO) [19], amongst them poly(acrylonitrile) (PAN) [20,21]. While pure PAN does not serve as an ideal substrate for cell adhesion and proliferation, water-stable blends of PAN with gelatin, maltodextrin, casein, etc.…”

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.
