Fig 9. Microscopic characterization of the morphology of NIH 3T3 cells following exposure to Pt-NP.

NIH 3T3 cells were cultivated either without any additional Pt particles as reference (A) or in culture medium containing 25 μg/ml (B), 50 μg/ml (C) and 100 μg/ml (D) of the Pt-NP. The images demonstrated highly uniform cell adhesion without any morphological impairment throughout the cell cultures assays with varying Pt-NP concentrations. Size of bars: 200 μm.
