The aim of this study is to evaluate the citotoxicity and genotoxicity of silver nanoparticles adsorbed on fumed silica (AgNP_SiO 2) and comercial titanium dioxide (TiO 2) to mammalian cells. The ...

Because diatom cell walls are comprised of opaline silica — essentially, glass — they remain preserved in sediments even after their organic components have decomposed. The shape of diatom cell walls ...
