In the original version of this article [1], there were three errors:
-
In the description of the test for cell viability, “4 μM ethidium bromide” should be replaced by “4 μM ethidium homodimer-1 (EthD-1)”.
-
In the Results and discussion section, the sentence “The surface morphology of gelatin matrix is visualized using AFM and SEM, respectively (Fig. 1b and c)” should read “The surface morphology of gelatin matrix is visualized using SEM and AFM, respectively (Fig. 1b and c).”
-
In the Results and discussion section, the sentence “AFM images also depicted a relatively smooth gelatin surface with an RMS Rq of 155.6 ± 18 nm (Fig. 1d)” should read “AFM images also depicted a relatively smooth gelatin surface with an RMS Rq of 155.6 ± 12.3 nm (Fig. 1d)”.
