3D rendering of an easyScan DFM image of Platinum coating on a biomedical device. Topography of the surface is important to determine coverage of the coating and roughness - which can effect susceptibility to corrosion.

The distance from the highest peaks to the deepest caverns is about 700 nm.

The image to the left is the 2D scan of the Pt surface that was used for the animation. The scan size is 11.9 microns.

The 3D animation was rendered with the SPIP software.
