Electrospinning of nanofibers has developed quickly from a laboratory curiosity to a highly versatile method for the preparation of a wide variety of nanofibers, which are of interest from a fundamental as well as a technical point of view. A wide variety of materials has been processed into individual nanofibers or nanofiber mats with very different morphologies. The diverse properties of these nanofibers, based on different physical, chemical, or biological behavior, mean they are of interest for different applications ranging from filtration, antibacterial coatings, drug release formulations, tissue engineering, living membranes, sensors, and so on. A particular advantage of electrospinning is that numerous non‐fiber forming materials can be immobilized by electrospinning in nanofiber nonwovens, even very sensitive biological objects such as virus, bacteria, and cells. The progress made during the last few years in the field of electrospinning is fascinating and is highlighted in this Feature Article, with particular emphasis on results obtained in the authors' research units. Specific areas of importance for the future of electrospinning, and which may open up novel applications, are also highlighted.

“…Recently, it has been demonstrated by some of us that polystyrene and polyacrylates can be processed from water by latex suspension (solid content about 25%) electrospinning in the presence of a small amount of a water soluble polymer. [25,26] Extraction of the resulting nanofibers with water yields stable nanofibers of polystyrene or polyacrylates. ''Green electrospinning'', [24] which could be defined as an approach which would alleviate concerns regarding safety, toxicology and environmental problems, could be accomplished by electrospinning from aqueous suspensions.…”

Poly(hexamethylene adipate)-PEO block copolymers (PHA-b-PEO) with different PEO contents were synthesized and processed to aqueous suspensions with high solid contents by a solvent displacement method followed by dialysis. The best suspension displayed a solid content of 16 wt.-% and an average particle size of 108 nm. This suspension was mixed with a small amount of high molecular weight PEO and Brij78 and electrospun into corresponding nanofibers. After extraction with water, nanofibers of PHA-b-PEO were obtained. Electrospinning of aqueous suspensions of biodegradable polyesters alleviates concerns regarding safety, toxicology and environmental problems, which are associated with spinning of such polyesters from harmful organic solvents and thereby offers novel perspectives for applications in medicine, pharmacy and agriculture. Electrospinning of polymers from aqueous suspensions avoiding harmful organic solvents is suggested to be "green electrospinning".

“…[2] Among many other advantages, electrospinning is a straightforward method for the preparation of composite materials simply by the use of ternary solutions consisting of a solvent, a polymer, and a third component. This has been shown, for example, for latex-based formulations, [3,4] nanoparticle-or carbonnanotube-based formulations [5][6][7][8] and also for biological components such as viruses, [9] living bacteria, [10][11][12] and living cells. [13] The use of highly complex biological systems such as living bacteria or living cells is of great interest for the preparation of novel polymer systems with complex functionality.…”

Physically crosslinked PVA-hydrogel microparticles are utilized for encapsulation of E. coli and M. luteus. The bacteria survive dry storage or treatment with bacteria-hostile organic solvents significantly better than unprotected bacteria as proven by culture-test experiments. The bacteria-protecting PVA microparticles are available for standard polymer-solution-processing techniques, as exemplarily shown by co-electrospinning of living bacteria encapsulated in dry PVA-hydrogel microparticles together with PVB-, PLLA-, and PCL-form organic solvents.
