The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the integrity of the fluorescence image of PBMCs in Fig. 9. The authors are not able to determine precisely how this issue arose and due to the time lapsed cannot reliably provide the raw data. An expression of concern will continue to be associated with the article unless we receive conclusive evidence regarding the reliability of the data.
