Cytotoxicity tests of the extracts of studied samples.
The relative viability of the cells (RVC) decreased when the
concentration of cells in the medium increased. It is important
to note that the RVC of nanoscale nickel-free austenitic stainless

corrosion of the studied samples in a biological environment such as
a cell culture medium.
