Abstract
A method of producing a nanoscale structure having substantially immobilized nanoparticles arranged at a predetermined patterned is generally disclosed. First, a curable polymeric solution is placed within a well defined by a wafer. The curable polymeric solution includes a curable polymeric material and a magnetically coated nanoparticle. The well is positioned adjacent to an atomically-smooth medium. A recording head is moved in a predetermined manner to produce a magnetic field profile that substantially immobilizes the magnetically coated nanoparticle within the curable polymeric solution in the well. The curable polymeric solution is cured such that the magnetically coated nanoparticle remains substantially immobilized after the magnetic field profile is removed.

A method of producing a nanoscale structure having substantially immobilized nanoparticles arranged at a pre-determined patterned, the method comprising:
- placing a curable polymeric solution within a well defined on an etched surface of a wafer, wherein the curable polymeric solution comprises a curable polymeric material and a magnetically coated nanoparticle;
- wherein the well is positioned adjacent to an atomically-smooth medium;
- moving a recording head in a predetermined manner to produce a magnetic field profile that substantially immobilizes the magnetically coated nanoparticle within the curable polymeric solution in the well, wherein the recording head is positioned on an opposite surface of the wafer from the wells;
- curing the curable polymeric solution such that the magnetically coated nanoparticle remains substantially immobilized after the magnetic field profile is removed, and
- removing the cured polymeric solution including the substantially immobilized magnetically coated nanoparticle from the well.
A method of producing a nanoscale structure having substantially immobilized nanoparticles arranged at a pre-determined patterned, the method comprising:
- mixing a curable polymeric material, a photoinitiator, and a magnetically coated nanoparticle to form a curable polymeric solution;
- dropping the curable polymeric solution into a well defined by a silicon wafer, wherein the well is positioned adjacent to an cobalt alloy medium;
- moving a transducer in a predetermined manner via a computer program to produce a magnetic field profile that substantially immobilizes the magnetically coated nanoparticle within the curable polymeric solution in the well, wherein the transducer is positioned on an opposite surface of the silicon wafer from the wells;
- applying ultra-violet light to the well to cure the curable polymeric solution such that the magnetically coated nanoparticle remains substantially immobilized after the magnetic field profile is removed, and
- removing the cured polymeric solution including the substantially immobilized magnetically coated nanoparticle from the well.
