Interaction of silver nanoparticles with algae and fish cells: a side by side comparison

Table 1 AgNP behavior in exposure media for algae and fish cells

	Algae exposure medium [26]	Fish cell exposure media [27]
	Algae exposure medium [26]	L-15/ex	L-15/ex w/o Cl	d-L-15/ex
Medium ionic strength (mM)	3.44	173.0	177.1	72.0
Size of AgNP (nm)	38–73	200–500	1000–1750	40–100
Zeta potential of AgNP (mV)	−23 to −28	−15	−10	−20
Dissolution of AgNP (% of total Ag)^a	1.7%	1.89%	0.67%	0.40%

^aThe level of dissolution of AgNP represents the mean of dissolution data obtained using two different methods to separate dissolved silver from particles: ultrafiltration and ultracentrifugation. Values given are the mean of the average data obtained for each method, carried out three independent times
