In nanoscale chemomechanical patterning, an atomic force microscope (AFM) probe is used to scribe a flat silicon surface under a solution of reactive molecules, attaching a layer of the molecules to the scribed line. This technique was previously used to functionalize silicon surfaces using a moderate range of scribing forces (5 µN to 80 µN). Here we will present a study focusing on the smaller forces (1µN to 5 µN) on both silicon and germanium surfaces resulting in significantly reduced tip wear and yielding lines down to 20 nm wide. We will also present the extension of chemomechanical patterning to include the attachment of proteins to the functionalized lines.
