Controlled-release and preserved bioactivity of proteins from (self-assembled) core-shell double-walled microspheres [Retraction]

Abstract

Yuan W, Liu Z. Controlled-release and preserved bioactivity of proteins from (self-assembled) core-shell double-walled microspheres. Int J Nanomedicine. 2012;7:257–270.The Editor-in-Chief and Publisher of the International Journal of Nanomedicine have been alerted to unacceptable levels of image duplication in the published article.The affected figures within the article presented above are:• Figure S3 (B) and (C) are duplicates of Figure 2 Panel I (A) and (B);• Figure 2 Panel I (E) is a duplicate of Panel I (C);• Figure 2 Panel II (B) and (C) are duplicates of Panel II (A);• Figure SI Panel II (A) is a duplicate of Figure 2 Panel II (D);• Figure SI Panel II (C) is a duplicate of Figure 2 Panel II (E);• Figure 5 (B) is a duplicate of 5 (A);• Figure S4 (A) is a duplicate of Figure S1 Panel I (A);• Figure S4 (B) is a duplicate of Figure SI Panel I (B);• Figure SI Panel (F) is a duplicate of Panel I (C);• Figure 1D and F are duplicates of Figure 9A and D, respectively, in paper Yuan W, Zhang Y, Wu F, Li H, Cai Y, Zhang Y, Han M, Jin T. Preparation of protein-loaded sustained-release microspheres via ‘solid-in-oil-in-hydrophilic oil-in-ethanol (S/O/hO/E)’ emulsification.
