There is evidence that nanoparticles (NP) can enter the bloodstream following deposition in the lungs, where they may interact with platelets. Polystyrene latex nanoparticles (PLNP) of the same size but with different surface charge-unmodified (umPLNP), aminated (aPLNP), and carboxylated (cPLNP)-were

P-glycoprotein/MDR1 (P-gp) is a well-characterised membrane transporter relevant in drug disposition and multi-drug resistance. In this study, we aimed to investigate how far nanoparticulates impair the function of the P-gp transport system and which particle properties govern these interactions. Expression
