Description
The publisher and editor of the International Journal of Nanomedicine issued an expression of concern in 2026 about a 2017 paper by Cai and colleagues. That paper described a nanoparticle aimed at bone-resorption surfaces, designed to deliver a gene-silencing molecule against osteoporosis. After publication, the authors themselves reported that a wrong image had slipped into two panels of a key figure. The journal's own check found unexpected similarities between those panels, which should have shown different treatment conditions.
Asked for the original images, the authors could not supply data from experiments run years earlier. The journal therefore cannot resolve the figure concerns. The editor states that the concerns do not undermine the overall validity of the reported findings. Readers are advised to treat that figure with caution. The notice stays open: the journal promises to reassess if new information appears.
