Abstract: A method of manufacturing a synthetic nanopore device for DNA sequencing disclosed herein includes providing a base template, forming a guiding layer on top of the base template, and forming a photoresist layer on top of the guiding layer. The photoresist layer is patterned, and the guiding layer is etched for form a guiding pattern. The photoresist layer is removed to form a guiding template and a self-assembled monolayer is deposited on at least a portion of the guiding template to form a patterned template. The patterned template is exposed to one or more etch processes to form a nanoimprint lithography template. A membrane is imprinted with the nanoimprint lithography template to form an array of nanopores in the membrane.

Abstract: A method of forming patterned magnetic media disclosed herein includes patterning a guiding layer on a substrate to form a nucleation guiding pattern. A layer of magnetic material is formed over the nucleation guiding pattern. The magnetic material may comprise a non-magnetic segregant. Magnetic grains are grown in a down-track direction and in a cross-track direction responsive to the nucleation guiding pattern and the non-magnetic segregant forms grain boundaries between the magnetic grains.
