Abstract
Expression of concern for ‘Gadolinium embedded iron oxide nanoclusters as T1–T2 dual-modal MRI-visible vectors for safe and efficient siRNA delivery’ by Xiaoyong Wang et al., Nanoscale, 2013, 5, 8098–8104, https://doi.org/10.1039/C3NR02797J.
Nanoscale is publishing this expression of concern in order to alert our readers that we are presently unsure of the reliability of the data reported in Fig. 8.
The authors have provided a replacement figure for consideration and say that the new data does not affect the conclusions of the paper. The Royal Society of Chemistry has asked the affiliated institution to investigate this matter and establish whether the replacement images provided by the authors provide an accurate representation of the experiments that were conducted and confirm the integrity and reliability of the new data provided.
An expression of concern will continue to be associated with this manuscript until we receive information from the institution on this matter.
