The authors wish to make the following corrections to this paper [1].
In the original publication, there were mistakes in Figure 4 and Figure 5 as published. The fluorescence microscopy images of biofilm formed on the glass surface by S. aureus 3515 were prepared by a Ph.D. student who is not a co-author of this paper. Thus, these images involve copyright issues and need to be corrected. The corrected Figure 4 and Figure 5 appear below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
Figure 4.
Fluorescence microscopy images of biofilm formed on the glass surface by S. aureus 3515 before aPDI (a); after photodynamic inactivation with MB alone as a photosensitizer (b); after photodynamic inactivation with MB+AuBNPs as a photosensitizer (c); after photodynamic inactivation with MB+AuChNPs as a photosensitizer (d). In the presence of the SYTO 9 and propidium iodide mixture, bacteria with intact cell membranes stain fluorescent green, whereas bacteria with damaged membranes stain fluorescent orange/red.
Figure 5.
Fluorescence microscopy images of biofilm formed on the glass surface by S. aureus 3375 after the first (a), second (b) and third (c) exposures to laser light in the presence of MB alone at a nontoxic concentration of 31.25 mg L−1. In the presence of the SYTO 9 and propidium iodide mixture, bacteria with intact cell membranes stain fluorescent green, whereas bacteria with damaged membranes stain fluorescent orange/red.
