How does an AFM work?
In the dark you scan with your finger over the table
• high and round
• hard and soft
• sticky
• warm and cold
Brain convolutes the sensations into an image
Breakfast Table
AFM convolutes nanoscale objects on the surface into a3D topography map plus different material properties

Imaging in Liquid:Design Consideration of the AFM Scanner
• Top down scanning:
-> no electronics under the sample plate
• Pendulum design and separated piezo plates for unperturbed scanning in xyz, low mechanical noise, fast scanning
• Atomic and Molecular Resolution
• Open liquid cell / closed cell /flow-through cell

Scanner: Balanced Pendulum – Ultimate Resolution
Y scan
Laser tracking spot remain fixed relative to AFM cantilever
Balanced pendulum Scanner: scanning faster, more accurate control in XYZ, less noise
Traditional Tube ScannerSimple pendulum: scanning slower, less accurate during turn around, more noise
