Study on Gelatin Hydrogel for Drug Delivery Retracted Due to Image Overlap Concerns

A scientific study detailing a new method for delivering the asthma drug salbutamol sulphate via gelatin-based swellable hydrogels has been retracted from the Springer Nature journal 'Polymer Bulletin'. The retraction was issued by the Editors-in-Chief following concerns about overlapping microscopy images in the paper's toxicity evaluation, which undermined the reliability of the presented data.
