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

Table 2 Effect of TiO ₂ and ZnO agglomerated engineered nanoparticles EPs on the average number of giant unilamelar phospholipid vesicles (GUVs) per micrograph

EPs	t[min]	GUVs N_test ± SD	GUVs N_control ± SD	Micrographs M_test	Micrographs M_control	Difference in N	p	P(α = 0,05)
TiO₂	20	8,6 ± 3,6	8,7 ± 3,8	151	151	−1%	0,913	0,03
TiO₂	50	13,4 ± 5,8	14,8 ± 7,0	155	148	−10%	0,465	0,51
ZnO	20	5,2 ± 2,3	6,3 ± 2,8	156	145	−17%	3.10^-4*	0,93*
	50	6,5 ± 3,5	9,1 ± 4,3	155	144	−28%	3.10^-8*	1,00*

The table shows the time of incubation (t), the average number of GUVs per micrograph of the test and of the control suspensions (N_test and N_control, respectively) with their standard deviations (SD), the number of harvested micrographs of the test and of the control suspensions (M_test and M_control, respectively), the difference between the number of GUVs in the test and in the control suspensions, the statistical significance (p value) of the t-test subject to the difference between the test and the control suspensions, and the corresponding statistical power P at α = 0,05. Asterisks denote that the difference is statistically significant and of sufficient power.
