Tapping Mode AFM Image Using a Fluid Cell
 
Fluid tapping mode AFM allows real time three dimensional imaging of biological systems in liquid environments. This 10um x 10um area shows domains in a Langmuir Blogett (LB) film. The smallest domain size is ~40nm. This image was collected under a physiological buffer solution using the Dimension 3000 in Fluid Tapping mode AFM. The right image is the surface topography and the left image is the simultaneous phase contrast image.
