Abstract

Barbari GR, Dorkoosh F, Amini M, et al. Synthesis and characterization of a novel peptide-grafted Cs and evaluation of its nanoparticles for the oral delivery of insulin, in vitro, and in vivo study. Int J Nanomed. 2018;13:5127–5138.The Editor in Chief and Publisher of International Journal of Nanomedicine wish to retract the published article. The journal was notified of the potential duplication of images in Figure 4 and Figure 5 of the published article. It was observed that Figure 5 was an inverted version of Figure 4. The authors were asked for an explanation but were unable to provide a satisfactory response or provide the original raw data for the images.
