What to know about Nanotechnology

Researchers from RIKEN and the University of Münster have developed a synthetic peptide hydrogel called FQ(Pyr) that features an electrically polarized, self-healing structure. The material's organized nanofibers and water channels may allow for applications in artificial muscles and smart drug delivery.

What happened

Single synthetic peptide forms electrically polarized, self-healing hydrogel Sadie Harley Scientific Editor Robert Egan Senior Editor Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) and RIKEN Pioneering Research Institute (PRI) in…

Why it matters

Based on a single synthetic peptide called FQ(Pyr), the new hydrogel has a highly organized structure made of nanofibers containing tiny water channels.

Common ground

The molecules within each nanofiber all point in the same direction, creating electrical polarization along the fiber.
