Correction to: Nature Protocols https://doi.org/10.1038/s41596-023-00951-3, published online 26 February 2024.

In the version of the article initially published, the sentence “The presence of B(OH)3 significantly increases the T1 relaxation time” was missing from the Fig. 11 caption. Additionally, the wrong Reporting Summary was included. The caption has now been amended and the correct Reporting Summary can be found online.
