The main effects induced by Si/SiO2 QDs on the phospholipid monolayer. In the absence of FBS, the interaction with QDs caused the expulsion of PC molecules and their oxidative injury which affected the structure of phospholipids and disturbed their organization creating holes in the monolayer. By contrast, QDs covered with protein corona strongly interacted with PC and were incorporated among the lipids, increasing the monolayer’s stiffness.
