Correction to: Nature Communications https://doi.org/10.1038/s41467-020-15822-8, published online 27 April 2020.

In the original version of this Article “5,5′-dithiobis-(2-nitrobenzoic acid)” was incorrectly written as “5,5′-dithiobis-(2-nitrobenzoic) acid”, and in Eq. (1) the upper limit of the summation in the denominator “n” was incorrectly written as “T”.

This has been corrected in both the PDF and HTML versions of the Article.
