Patent ID: 8505110

Claim:
An apparatus for fabricating catalyst retaining structures; comprising: a first plurality of atomic force microscopes, each atomic force microscope comprising: a cantilever having a free end; an atomic force microscope tip attached to the free end of the cantilever; a nanotube attached to said atomic force microscope tip, said nanotube having a tip configured for orientation toward a substrate; and a second plurality of atomic force microscopes, each atomic force microscope comprising: a cantilever having a free end; an atomic force microscope tip attached to the free end of the cantilever; a nanotube attached to said atomic force microscope tip, said nanotube having a tip configured for orientation toward a substrate; in which each cantilever is coupled to a silicon chip; in which the first and second plurality of atomic force microscopes are attached to respective first and second closed-loop z-direction scanners; and in which the first and second closed-loop z-direction scanners are driven by a closed loop x,y direction scanner.
