In this article, the authors found errors in Figure 1a and Figure 3 that were caused by the accidental mislabelling of the raw images acquired from the scanning electron microscopy experiments. These images were intended to illustrate the structural features of the biomaterials; however, they did not impact the main conclusions of the study. These figures should have appeared as shown below.

The original article has been corrected.
