“…The IONPs-CIT used to study the cytotoxicity, after quantification, presented Fe3O4 concentration equal to 2.36 mg. mL -1 and then IONPs-CIT solutions were prepared at concentrations of 5, 25, 50, 100, 150 and 300 µg/mL. The colorimetric method with MTT assess cell viability (Nepomuceno et al, 2021;Nandi et al, 2017), determining the minimum concentration necessary to obtain more than 50% viable or non-viable cells, with quantification of the activity of dehydrogenase from the reaction products NADH or NADPH, which reduces the activity of the MTT formazan crystals in living cells (Nepomuceno, et al, 2021). According to the Standard (2009), ISO 10993-5: 2009, it is established that the feasibility of cells can be determined through metabolic activity.…”

“…Optical density was measured with a spectrophotometer (Awareness Technology Stat Fax 2100, 425-540 nm, Palm City, FL, USA). Three wavelengths were used to discern the absorbances measured by the spectrophotometer because the size of the molecules, density, dilution, and other factors can influence the physical properties of the samples and thus interfere with the ideal wavelength (26) .…”

“…A densidade óptica foi quantificada em espectrofotômetro (Awareness Technology Ine/ Stat Fax 2100, 425 nm -540 nm, Palm City, FL, EUA). Utilizaram-se três comprimentos de onda para melhor discriminar os valores de absorbância obtidos no espectrofotômetro, pois o tamanho das moléculas, densidade, diluição e outros fatores podem influenciar as propriedades físicas das amostras e, assim, interferir diretamente no comprimento de onda ideal (26) . A viabilidade celular foi determinada pela equação: onde VC é a viabilidade celular e abs é a absorbância.…”
