Description
A 2026 retraction notice in the journal Nanomaterials withdraws a 2019 article by Ayman M Atta and co-authors on pH-responsive plastic nanospheres for use in microgel emulsions. After publication, readers raised concerns about the integrity of the paper's figures. Retractions of this kind signal that editors no longer trust a paper's results.
An editorial investigation found signs of inappropriate image editing and duplication in panels of five figures, including material overlapping with earlier published articles. The authors cooperated and supplied supporting material, but the board could not resolve its concerns and lost confidence in the images. The editor-in-chief approved the retraction; the authors gave no comment.
