A method for targeted deposition of a nanotube on a planar surface includes
providing a ram made from elastomeric material and having a relief
structure on its surface. A microfluid capillary system, with an inlet and
an outlet, is then formed by applying the ram to a planar substrate. A
dispersion of nanotubes is brought into contact with the inlet, thereby
enabling capillary force to disperse the nanotubes. through the microfluid
capillary system. The resulting dispersion of nanotubes is then dried and
the ram removed.
