Abstract

Correction for ‘Plasticizer and catalyst co-functionalized PEDOT:PSS enables stretchable electrochemical sensing of living cells’ by Jing Yan et al., Chem. Sci., 2021, 12, 14432–14440, DOI: 10.1039/d1sc04138j.

The authors regret that there was an error in the equation of the calibration curve of PPL/PDMS in Fig. 3. The correct version is shown below.

Fig. 3. (A) CVs of different electrodes obtained in 10 mM K₃[Fe(CN)₆]. Inset: the enlarged view for CV of the PP electrode. (B) Schematic illustration of the electrocatalysis mechanism. (C) CVs of different electrodes with and without 1 mM H₂O₂. (D) Amperometric responses of PPL/PDMS (black lines) and PPLC/PDMS (red lines) electrodes to H₂O₂ at a potential of +0.55 V (vs. Ag/AgCl) to increasing H₂O₂ concentrations. Inset: the enlargements of amperometric responses framed in blue. (E) Calibration curves of PPL/PDMS and PPLC/PDMS electrodes to increasing H₂O₂ concentrations (data presented as mean ± standard error, n = 3). (F) Calculated LOD and sensitivity of PPL/PDMS and PPLC/PDMS electrodes to H₂O₂.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
