RETRACTED ARTICLE: Preparation of smart PVP/HPMC based IPN hydrogel, its characterization and toxicity evaluation

Following a complaint and technical (editorial) investigation, the authors were requested to provide essential documentation to verify the reliability, validity, and ethical compliance of the study published. Despite repeated reminders, the required documentation was not provided. Specifically, the authors did not correspond or supply Raw Data: Original, unedited high-resolution microscope capture files and supporting raw laboratory datasets for the toxicity evaluation. Image Documentation and proof of originality: Original source files of Figure 11 (histological panels), with confirmation of their originality and linkage to the raw dataset (due to suspected image reuse and unauthorized duplication across panels).
