Nanoparticle Assemblies on Nanoinjection-Molded Polymer Templates

A mass-producible method for fabricating nanoparticle assemblies using nanoinjection-molded polymer templates with deposition and selective removal has been developed and characterized in this work. Results are demonstrated for assembly of multiple nanoparticle sizes and types in 1-D and 2-D formats over large areas. Template dimensions such as width and depth are used to control the assembled structures, including the quantity and type of nanoparticles in the assembly. This method offers a high-throughput, low-cost approach to nanoscale assembly for applications in optical, electronic, and biomedical devices.
