Effect of Ag NPs or Fe₃O₄ NPs with and without photothermal effect on the in vitro count of B. hominis (cells ×${10}^4$) with different concentrations after 24 h of incubation

Group (dosage of treatment)	Ag NPs		Fe3O4 NPs
	Dark	Light	Dark	Light
	Mean ± SD (growth inhibition $\text{\%}$)
Untreated	40±2.5	40±2.5	40±2.5	40±2.5
10 μM	30±3.3 (40%)	8±0.85* (80%)	24±2.35 (40%)	10±1.7* (75%)
20 μM	17±2.1* (57%)	6.1±1.05* (85%)	14.1±2* (65%)	7.5±1.25* (81%)
30 μM	10.1±0.2* (75%)	4±0.85* (90%)	8.1±1.65* (80%)	6±0.85* (85%)

Values are expressed as mean ± SD

*Statistically significant difference compared to untreated ($p<0.05$)

Percent of growth inhibition = ($a-b/a$), where “$a$” is the mean number of parasites in NTC and “$b$” is the mean number of parasites in treated cultures
