Bioinspired electrospun knotted microfibers for fog harvesting.

Tying the knot: Knotted microfibers with fog collection abilities (see picture) are fabricated by a facile coaxial electrospinning method. This method is promising for rapid, large-area, and low-cost production of fabric materials that could be used to relieve drought in arid areas. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
