Figure 8
(a) Fibers with diameter of 47 ± 4.9 nm were observed from released solution of hydrogel 2; (b) AFM images of cationic peptide mimics 2a at 221 µM, which was prepared with DMSO (5%): water without forming the hydrogel, showed a mixture of thin fibers with lack of junction zones and spheroidal aggregates. Scale bar of AFM images was denoted as 1 µm. and (c) fibers released solution from hydrogel 2 exhibited bactericidal activity, with complete kill observed against S. aureus, meanwhile peptide mimics 2a as a monomer did not show notable reduction.
