Soft‐lithographically fabricated nanofluidic channels for single‐DNA measurements
Source abstract
Abstract
We report on the fabrication of submicrometer wide channels by applying advanced soft lithography and focused ion beam patterning. Using so‐called hard PDMS, mechanically stable channels are obtained down to 375 nm width. Channels down to ∼100 nm width are made from Ormostamp. The channels can be filled with DNA solution. Manipulation of the DNA transport through the channels is accomplished by applying electrophoretic forces.
