Endocytosis, the mechanism by which live cells internalize exogenous substances, is thought to be a key step in drug or gene delivery. The filamentous M13 bacteriophage has attracted extensive research interest as a biomaterial. On page 413, in the quest for biomedical applications, Z. Niu and co-workers investigate the internalization mechanism, the interaction with cell membrane, and the pH map of M13 in different cell lines.
