Correction: Label-free non-invasive fluorescent pattern discrimination of thiols and chiral recognition of cysteine enantiomers in biofluids using a bioinspired copolymer-Cu²⁺ hybrid sensor array regulated by pH (Journal of Materials Chemistry B (2018) 6 (6877-6883))

During the revision of the original manuscript, the caption in Fig. 3i on page 6881 was wrong. It should be corrected as L-Cys, rather than D-Cys. Although the results are not affected, the error led to a confusing presentation in the paper. We apologize for this error and any inconvenience to the readers. The corrected Fig. 3i is provided below.
