Abstract:
1. A method of forming functional nanoparticles, comprising: forming a multi-layer substrate comprising, a removable layer and a sacrificial material layer coupled to the removable layer; patterning the sacrificial layer using a first imprint lithography template to provide a patterned layer having a residual layer and a pattern of a plurality of protrusions and a plurality of recessions; transferring the pattern of protrusions and recessions into the removable layer; depositing functional material within recessions of the removable layer; patterning the functional material to provide a patterned functional material layer having a plurality of pillars in the removable layer; wherein the patterning of the functional material includes imprinting using a second imprint lithography template and wherein the second imprint lithography template is substantially planar, and, releasing the pillars from the multi-layer substrate, the released pillars forming functional nanoparticles comprising the functional material.
