Submission received: 18 November 2025 / Accepted: 19 November 2025 / Published: 24 November 2025
The journal retracts the article entitled “High-Sensitivity Biosensor Based on Glass Resonance PhC Cavities for Detection of Blood Component and Glucose Concentration in Human Urine” [1], cited above.
Following publication, a number of concerns were brought to the attention of the Editorial Office relating to image duplication, relevancy of references, and authorship in this publication [1].
Adhering to our procedure, an investigation was conducted by the Editorial Office and the Editorial Board that identified significant concerns relating to the integrity of peer-review process. Further concerns identified included an image overlap between this article [1] and an earlier publication [2] produced by a different authorship group, presenting different experimental conditions, and a significant number of irrelevant citations. Finally, despite multiple follow-up with the authors, the Editorial Board were unable to verify the accuracy of the originally listed authorship list. As a result, the Editorial Board has lost confidence in the integrity of the findings and decided to retract this publication [1], as per MDPI’s retraction policy (https://www.mdpi.com/ethics#_bookmark30, accessed on 21 August 2025).
This retraction was approved by the Editor-in-Chief of Coatings.
The authors did not agree to this retraction.
