Immunofluorescence images showing the effect of direct exposure to a Control samples b Cu doped and c Ag doped Ti₃Au thin films on L929 cells’ morphology and actin cytoskeleton. For each sample following exposures, L929 cells were fixed and stained with anti-Phalloidin (middle panel) and counterstained for DNA with DAPI (left panel). Green and blue colour represents staining for Phalloidin and DAPI, respectively, while merged images for Phalloidin/DAPI staining are also shown (right panel). Scale: 20 μm
