Retraction: A highly antibacterial polymeric hybrid micelle with efficiently targeted anticancer siRNA delivery and anti-infection in vitro / in vivo

We, the named authors, wholly retract this Nanoscale article. We have recently found that we did not get approval from the Animal Ethics Committee at Xi'an Jiaotong University before performing the in vivo animal experiments, although we stated that we had approval in the published article. After repeating the animal experiments under the approved conditions, we found that the result on sample PEI in Fig. 8E was not consistent with the published result. We are therefore retracting this article to maintain the accuracy of the scientific record. Peter X. Ma was contacted but did not respond.
