RETRACTION: A Novel pH-Responsive Nanoniosomal Emulsion for Sustained Release of Curcumin from a Chitosan-Based Nanocarrier: Emphasis on the Concurrent Improvement of Loading, Sustained Release, and Apoptosis Induction

Abstract

RETRACTION: S. Haseli, M. Pourmadadi, A. Samadi, F. Yazdian, M. Abdouss, H. Rashedi, and M. Navaei-Nigjeh, “ A Novel pH-Responsive Nanoniosomal Emulsion for Sustained Release of Curcumin from a Chitosan-Based Nanocarrier: Emphasis on the Concurrent Improvement of Loading, Sustained Release, and Apoptosis Induction,” Biotechnology Progress 38, no. 5 (2022): e3280, https://doi.org/10.1002/btpr.3280.

The above article, published online on 30 June 2022 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, John A. Morgan; the American Institute of Chemical Engineers; the Society for Biological Engineering; and Wiley Periodicals LLC.

The retraction has been agreed upon following an investigation into concerns raised by a third party, which revealed inappropriate duplication of image panels between this (Figure 4) and another article published by an overlapping group of authors, depicting a different experimental condition.

The partial raw data provided by the authors could not address the original concerns, showed inconsistencies with the published results, and ultimately raised additional doubts about the study's overall reliability. Consequently, the editors have lost confidence in the presented data and decided to retract the paper. The authors’ institute has been informed of the allegations and the decision to retract but remained unresponsive. The authors disagree with the retraction.
