Correction: Zhu et al. Biodegradable and pH Sensitive Peptide Based Hydrogel as Controlled Release System for Antibacterial Wound Dressing Application. Molecules 2018, 23, 3383

During the course of a review of our publication, we found two errors in Figure 4b and Figure 9. We wish to make the following corrections to this paper [1]. We have inserted SEM and H&E images mistakenly, but the results and conclusions of the paper are not affected. We have provided the correct figures below.

All co-authors agree with the content of this correction and we would like to apologize for any inconvenience caused to the readers by these changes.

Figure 4. SEM images of homogeneous peptide-based bis-acrylate/AAc hydrogels before biodegradation: (a) Gel-1; (b) Gel-2; (c) Gel-3; (d) Gel-4. With the increasing of peptide-based bis-acrylate contents, the pore size of the hydrogels would decrease.
