Abstract
Correction for ‘Ratiometric fluorescent probes for selective and sensitive visualization of bacterial microenvironment protease activity’ by Qinghua Wang et al., Chem. Commun., 2019, 55, 5064–5067, https://doi.org/10.1039/C9CC00953A.
The authors regret that there were errors in Scheme 1 and the graphical abstract image in the original article.
While the peptide sequence “Phe-Leu-Glu-Phe” (FLEF) was correctly stated in the manuscript text, it was incorrectly labeled as FGLF in the structures of probes 1 and 2 in Scheme 1. Accordingly, the published structures of probes 1 and 2 should be revised as shown here.

The graphical abstract displays the same incorrect sequence (FGLF instead of FLEF) and shows the fluorophores attached at incorrect sites relative to the probe structure. The corrected image is provided here.
Graphical abstract
All data analyses presented in the original manuscript are accurate, and the results and conclusions remain unchanged.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
