Correction to: Nature Communications 10.1038/s41467-019-10685-0, published online 28 June 2019.
The original version of this Article omitted ‘The Ministry of Science, Research and the Arts Baden-Württemberg (MWK), Grant FKZ 7533-7-11-10-07 (IWWB-28)’ from the acknowledgements and has since been adjusted to read:
The research was supported by the ERC Starting Grant (DropCellArray, 337077), ERC Proof-of-Concept Grant (CellScreenChip, 680913) and the Ministry of Science, Research and the Arts Baden-Württemberg (MWK), Grant FKZ 7533-7-11-10-07 (IWWB-28). We would like to thank Dr. Gerald Brenner-Weiß from IFG (KIT, Institute of Functional Interfaces) for providing training and access to MALDI-TOF mass spectrometry, and Dr. Nicole Jung from IOC (KIT; Institute of Organic Chemistry) for providing training and access to LC-MS.
This has now been corrected in both the PDF and HTML versions of the Article.
