Effect of engineered TiO2and ZnO nanoparticles on erythrocytes, platelet-rich plasma and giant unilamelar phospholipid vesicles

Table 1 Characteristic properties of population of suspensions of agglomerated engineered nanoparticles

Engineered nanoparticles	pH	Zeta potential [mV]	Stability behaviour	Size (measured by DLS)
TiO₂ in PBS- citrate	7,9	−26	Incipient instability
ZnO in PBS- citrate	7,9	−29	Incipient instability
TiO₂ in 0,3 M glucose	4,4	−22	Incipient instability	600-4000 nm (average 1820 nm)
ZnO in 0,3 M glucose	6,6	−15	Incipient instability	100 – 1200 nm (average 431 nm)

The DLS measurements of TiO₂ and ZnO EP suspensions in glucose could be performed, but the DLS measurements of TiO₂ and ZnO EP suspensions in PBS citrate could not be performed due to fast sedimentation.
