In the original article, there was a mistake in Figure 1 as published. The structures given in Figure 1 for pyrocatechol violet and saccharides were incorrect. The corrected Figure 1 appears below.
Figure 1.
(A) Chemical structures of ARS, BPR, PR, PV, and 3-NPBA. (B) List of target saccharides. (C) Illustrated scheme of the indicator displacement assay utilizing the building blocks (i.e., a catechol dye and 3-NPBA) for the easy preparation of colorimetric sensing.
