Abstract

Barbari GR, Dorkoosh FA, Amini M, et al. Int J Nanomedicine. 2017;12:3471–3483 The Editor and Publisher of International Journal of Nanomedicine wish to retract the published article. Concerns were raised regarding the alleged duplication of features within the image shown in Figure 4. The first author responded to our queries but was unable to provide the original images for Figure 4. The first author explained they were responsible for the preparation of the SEM images and wishes to apologize to the readers and other authors for any errors that may have been introduced to the image which led to the retraction of the paper. However, all the authors accept responsibility for the integrity of the reported research and agree with the decision to retract the article. Our decision-making was informed by our policy on publishing ethics and integrity and the COPE guidelines on retraction. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”. This retraction relates to this paper
