Abstract
When it comes to spinning polymer fibers, spiders are much better than scientists. However, the authors have narrowed the gap: Extensive simulations show that for by judiciously oscillating the spinneret, instabilities can be tamed and extremely thin fibers can be extracted. Remarkably, this effect is independent of the rheology of the polymeric solution used. These ultrathin fibers open up a new length scale for applications ranging from photonics and organic field-effect transistors to artificial ligaments and scaffolds used in tissue culture.
