Abstract
Expression of concern for ‘High cytotoxic activity of ZnO@leucovorin nanocomposite based materials against an MCF-7 cell model’ by Mohamed Fathi Sanad et al, Anal. Methods, 2020, 12, 2176–2184, https://doi.org/10.1039/D0AY00498G.
The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the reliability of the FACS data in Fig. 7. An investigation is underway, and an Expression of Concern will continue to be associated with the article until a final outcome is reached.
