In Scheme 1, Step 5 AuNPs should read AgNPs. The corrected Scheme 1 is as follows:

Scheme 1 Synthesis of the pSTEC₄-AgNPs ligand


In Fig. 1A images a and b were incorrect. The corrected figure of Fig. 1A is as follows:

Fig. 1A UV–Vis spectra of (a) pSTEC₄-AgNPs (b) pSTEC₄-AgNPs with 100 nM Fe³⁺ concentration


In Fig. 5C notations i and ii were missing. The corrected figure is as follows:

Fig. 5C FT-IR spectra as a function of interaction of pSTEC₄ with the ferric ion, pH 5.0 adjusted by NaOH–H₃PO₄ buffer, T 2 min, 25 ⁰C.


Page 3, right column, 2 lines from bottom: "concentrations of Fe³⁺ from 25 nM to 5 nM" should read "concentrations of Fe³⁺ from 50 nM to 10 nM"

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