Toxicity Study of a Nanoparticle Containing Passivate Layer

The authors report on the cell toxicity study of a nanoparticle containing chromium(III) passivation. The toxicity of abrasion from zinc plated and nano-passivated screws was tested with human A549 cells. As a reference system we used the abrasion from zinc plated and thick layer passivated screws. The tests showed no toxic potential of the nanoparticle-containing passivation layer, as can be seen by the normal growing behavior of the cells in presence of the abrasion.
