Single-colloidal-particle microcontact printing.
We have utilized colloidal probe atomic force microscopy (AFM) in conjunction with microinterferometry to study the forces acting in the microcontact printing process. The procedure we have developed yields well defined asymmetric imprints on colloidal probes, which could find further application in interaction force measurements between Janus-type particles and surfaces.
