Plastic cantilevers for force microscopy
Abstract:
A method disclosed for producing polymer-based cantilevers for use in atomic force microscopy in a batch process. The method includes forming a mold in a mold material, for example PDMS, using a master cantilever, removing the master cantilever from the mold material to reveal a mold cavity, filling the mold cavity with plastic, for example polystyrene, to form a plastic cantilever in the mold, and removing the plastic cantilever from the mold, for example using adhesive tape or flexing the mold. At least one surface of the plastic cantilever can be coated with a reflective metal, such as gold. The plastic cantilever can be functionalized for use in magnetic force microscopy by attaching a probe tip formed of magnetic metal, for example a 10 μm nickel sphere.
