Abstract
Retraction of ‘Influence of 2-(diisopropylamino)ethyl methacrylate on acid-triggered hydrolysis of cyclic benzylidene acetals and their importance in efficient drug delivery’ by Minjie Tang et al., Polym. Chem., 2015, 6, 6671–6679, https://doi.org/10.1039/C5PY00734H.
The Royal Society of Chemistry, with the agreement of the authors, hereby wholly retracts this Polymer Chemistry article due to concerns with the reliability of the data.
Fig. 2d contains multiple duplicated features within the image.
Fig. 8 and S8 both show fluorescence microscopy images of HepG-2 cells following incubation with DOX-loaded micelles and free DOX (30 μg mL−1). The cell nuclei stained by DAPI in Fig. 8b for DOX-loaded PETD-0 NPs and Fig. S8a for free DOX appear identical.
Given the significance of these concerns, the findings presented in this paper are no longer reliable.
All authors were informed about the retraction of this article. Zujian Feng, Anjie Dong and Liandong Deng agreed with the decision, the other authors did not respond.
