Abstract
Expression of Concern for ‘One-pot synthesis of acid-degradable polyphosphazene prodrugs for efficient tumor chemotherapy’ by Na Zhou et al., J. Mater. Chem. B, 2020, 8, 10540–10548, https://doi.org/10.1039/D0TB01992E.
The Royal Society of Chemistry 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. 7 of the article.
A number of the haematoxylin and eosin (H&E) stained images in Fig. 7 have been duplicated in one of the authors’ publications in Journal of Materials Chemistry B, which has subsequently been retracted (https://doi.org/10.1039/D0TB01373K).
The Royal Society of Chemistry has asked the affiliated institution to investigate this matter and to confirm the integrity and reliability of the data presented in the article, and the accuracy of the response provided by the authors.
An expression of concern will continue to be associated with this manuscript until we receive information from the institution on this matter.
