Visual transparency analysis and cytocompatibility study. a Visual transparency comparison of three different nanoparticles (ivy, TiO₂, ZnO) dispersed in distilled water with three different concentrations (500 μg/ml, 100 μg/ml and 10 μg/ml), and b MTT assay to compare the cytotoxicity of three different nanoparticles (ivy, TiO₂, ZnO). Nanoparticles were gradiently diluted to 100 μg/ml, 50 μg/ml, 25 μg/ml, 5 μg/ml, 1 μg/ml, 0.2 μg/ml, 0.04 μg/ml and 0.008 μg/ml.
