Abstract
Expression of concern for ‘3D-printed magnetic Fe3O4/MBG/PCL composite scaffolds with multifunctionality of bone regeneration, local anticancer drug delivery and hyperthermia’ by Jianhua Zhang et al., J. Mater. Chem. B, 2014, 2, 7583–7595, https://doi.org/10.1039/C4TB01063A.
Journal of Materials Chemistry B 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. 2 of the article.
The Royal Society of Chemistry has asked the affiliated institution (Shanghai Sixth People's Hospital, Shanghai Jiaotong University) to investigate this matter and confirm the integrity and reliability of the data in Fig. 2. An expression of concern will continue to be associated with the article until we receive information from the institution regarding this matter.
