Both confocal imaging and flow cytometry demonstrated that MMC was distributed into nuclei after cellular uptake and intracellular drug delivery. More importantly, the systemically administered MP-PEG-FA NPs led to increased blood persistence and enhanced tumor accumulation in HeLa tumor-bearing nude mice. This study introduces a simple and effective strategy to design the anticancer drug–phospholipid complex-based targeted drug delivery system for sustained/controlled drug release.
