| description | PROBLEM TO BE SOLVED: To provide methods for uniformly depositing nanoparticles on a substrate over large areas.SOLUTION: The invention is directed to a method for positioning the nanoparticles on a patterned substrate. The method comprises: a step of providing a patterned substrate with selectively positioned recesses; and a step of applying a solution or suspension of the nanoparticles to the patterned substrate to form a wetted substrate. A wiper member is dragged across the surface of the wetted substrate to remove a portion of the applied nanoparticles from the wetted substrate, and then a substantial number of the remaining portion of the applied nanoparticles are left disposed in the selectively positioned recesses of the substrate. The invention is also directed to a method of making carbon nanotubes from the positioned nanoparticles. |
