Session S8 - Nucleic Acids II.
ORAL session, Wednesday afternoon, March 24

We will present a novel method of fabricating the nanopore arrays in the range of 10\~20 nm size utilizing Si processing. Using e-beam lithography and anisotropic wet etching with KOH, we make a series of V-grooves on the top of the wafer and one at the right angle on the bottom surface. This opens up a series of nanopores. The unique feature of electrically addressable nanopore arrays (EANA) allows us to control the ionic solution flow and detect DNA translocations in each pore independently. Preliminary results of application of EANA device for studying biomolecules will be shown. This work is supported by NSF-NER-0304325.
