Abstract
We report, for the first time, fabrication of sub-10 nm pores in freestanding polymer membranes via a simple, cost effective, high throughput but still deterministic fabrication method. Nanoimprint lithography (NIL) was combined with a polymer reflow process to build the polymer nanopore membranes in SU-8. The fabricated nanopore membranes were successfully employed for transient current measurements during translocation of DNA molecules through the nanopores. The DNA capture rate increased proportional to the square of the nanopore diameter.
