Fig. 1From: Controlling supramolecular filament chirality of hydrogel by co-assembly of enantiomeric aromatic peptidesChemical structures of LMW-L1 and LMW-D1, and the illustration of self-assembly mechanisms for three kinds of low molecular weight (LMW) hydrogels that formed at pH 7.4 aqueous solution. Homodimerization of LMW-L1 or LMW-D1 forms hydrogel with isotropic or anisotropic nanofibers, while the mixture of enantiomer LMW-L1 and LMW-D1 co-assembles to form chiral nanofibrous hydrogel consisting of heterodimers.
