Abstract

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.
