Versions Notes
The journal retracts the article, “Poly (N-vinylcaprolactam-grafted-sodium alginate) Based Injectable pH/Thermo Responsive In Situ Forming Depot Hy-drogels for Prolonged Controlled Anticancer Drug Delivery; In Vitro, In Vivo Characterization and Toxicity Evaluation” [1].
Following publication, concerns were brought to the attention of the publisher regarding overlapping figures with a previously published article [2], with no common authorship and representing different experimental conditions.
Adhering to our complaints procedure, an investigation was conducted by the Editorial Office and the Editorial Board. In this situation, each author was contacted individually to confirm their contribution, and provide original figures. While the authors fully cooperated with the Editorial Office during the investigation, they were unable to satisfactorily explain the overlapping of figures, nor were they able to meet the required quality standards of raw images in order to consider a correction as per the journals original image requirements policy (https://www.mdpi.com/journal/pharmaceutics/instructions#oriimages). As a result, the Editorial Board and Editor-in-Chief were unable to confirm the reliability of the findings and subsequently decided to retract the paper as per MDPI’s retraction policy (https://www.mdpi.com/ethics#_bookmark30).
This retraction was approved by the Editor-in-Chief of Pharmaceutics.
The authors disagree with this retraction.
