Correction to: Communications Chemistry 10.1038/s42004-023-01035-9, published online 2 November 2023
In the version of this article initially published, there were errors in the presentation of structures shown in Fig. 1, where the CatD-P3 probe structure was missing a carbon atom in the PEG tag, where the propargyl moiety in alkyne-PEG(5 K)-OMe used for the click chemistry was previously depicted as an ethynyl moiety. In Fig. 2 and Supplementary Note 4, the PEG reagent used to synthesize CatD-P3 was similarly depicted incorrectly. In addition, in Fig. 2, the charges of structure 2 were erroneously misplaced within the BODIPY fluorophore. The errors were visual and do not affect the results or conclusions in the article. Figures 1 and 2 and Supplementary Note 4 have now been updated in the HTML and PDF versions of the article.
