摘要：

Hydrogels with hierarchical alignment are described by balancing electronic repulsion and attraction among silk protein nanofibers. The nanofiber alignment is cruicial to the formation of these hydrogels, dependent on electric fields and the inherent repulsion from negatively charged silk, which induces alignment layer separation. Aligned cell growth on the hydrogels implies promising medical applications. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
