Correction and removal of expression of concern for ‘Natural steroid-based cationic copolymers cholesterol/diosgenin-r-PDMAEMAs and their pDNA nanoplexes: impact of steroid structures and hydrophobic/hydrophilic ratios on pDNA delivery’ by Zhao Wang et al., RSC Adv., 2021, 11, 19450–19460, https://doi.org/10.1039/D1RA00223F.
An independent expert has viewed the corrected data for Fig. 2b and has concluded that it is consistent with the discussions and conclusions presented.
This correction supersedes the information provided in the Expression of Concern related to this article.
The authors regret additional errors in the manuscript.
In Table 1 the units for Mn,NMR and Mn,GPC should be ×10 kg mol−1.
On page 19451, in the left column, in paragraph 2, line 9 and in the right column, in paragraph 3, line 10 the text ‘(dimethylamino)ethyl methacrylate (DMAEMA)’ should have been written as ‘2-(dimethylamino)ethyl methacrylate (DMAEMA)’.
The authors and the Royal Society of Chemistry apologise for these errors and any consequent inconvenience to authors and readers.
