Abstract
Expression of concern for ‘Promising antimicrobial and antibiofilm activities of reduced graphene oxide-metal oxide (RGO-NiO, RGO-AgO, and RGO-ZnO) nanocomposites’ by Sherif Elbasuney et al., RSC Adv., 2021, 11, 25961–25975, https://doi.org/10.1039/D1RA04542C.
RSC Advances is publishing this expression of concern in order to alert readers that concerns have been raised regarding the reliability of the antimicrobial activity photos in Fig. 10 and SEM images in Fig. 13. An investigation is underway, and an expression of concern will continue to be associated with the article until a final outcome is reached.
