Study on Gelatin Hydrogel for Salbutamol Delivery Retracted Due to Image Overlap

A study published in Polymer Bulletin, a Springer Nature journal, concerning the design of gelatin-based swellable hydrogels for controlled delivery of the asthma drug salbutamol sulphate has been formally retracted. The retraction was issued due to concerns regarding overlapping microscopy images in the toxicity evaluation section, which undermined the reliability of the presented data.
