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 [...].

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.

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.

Figure 9

In vivo toxicity assessment of hydrogels. Hematoxylin-eosin (H&E) stained tissue slices (liver, spleen, kidney, heart and lung) of mice injected with hydrogels after 24 h (the white scale bar is 200 µm).

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.
