Authors Xiangsheng Liu, Yu-Pei Liao, Xiang Wang, Ayman Ahmed, Ying Ji, Huan Meng, Andre E. Nel, and the Editor retract this work due to the inability to reproduce the claimed nanocarrier in the 4T1 breast cancer model. The authors suggest that the lysophosphatidylcholine prodrug has detergent-like properties that may disrupt the lipid bilayer. However, based on the inability to reproduce this nanocarrier, the authors retract the work, although the first author disagrees with the retraction.
