Abstract

The interaction between human osteoblast cells and CrN thin film was studied in vitro. CrN thin films were produced by cathodic arc plasma deposition. The surface was characterized by atomic force microscopy. Cell adhesion on the coatings was assessed by MTT assay and visualization. Cell cytoskeleton organization was studied by analyzing microtubule and actin cytoskeleton organization. Focal contact adhesion was monitored by analyzing vinculin density. The study found that the CrN thin film is a potential candidate as a protective coating on implantable devices that require minimal cellular adhesion.
