Formation of gels with aligned PA nanofibers. (A) Chemical structures of PAs used to form the gels (B) Molecular graphics representation of nanofibers formed by co-assembly of bioactive and backbone PA molecules (the longer PA in the fiber displays the bioactive signal), (C) An illustration depicting the formation of a gel with aligned PA nanofibers by pipetting a PA solution through a salt solution containing CaCl2.
