摘要：

Micelles with surface morpholino groups were stealthy at blood and normal tissue pH (7.4) due to the unprotonated hydrophilic morpholino groups on the surfaces. At tumor pH (<7), the micelle surfaces were positively charged because of the protonation of the morpholino groups, which promoted the cellular uptake of the micelles.
