摘要:
Accordingly, the present invention provides a method of forming an electrode having reduced corrosion and water decomposition on a surface thereof. A substrate which has a conductive layer disposed thereon is provided and the conductive layer has an oxide layer with an exposed surface. The exposed surface of the oxide layer contacts a solution of an organic surface active compound in an organic solvent to form a protective layer of the organic surface active compound over the oxide layer. The protective layer has a thickness of from about 0.5 nm to about 5 nm and ranges therebetween depending on a chemical structure of the surface active compound.

The present invention provides a method of reducing corrosion and water decomposition on a surface of an electrode having a titanium nitride conductive layer disposed on a substrate and estimating extent of reduction thereof. The electrode is immersed into a solution containing a hydroxyl-functional compound. Thereafter, a voltage is applied to the titanium nitride conductive layer of the electrode. The extent of oxidation of the titanium nitride conductive layer is correlated with the extent of formation of oxide of titanium nitride and/or the extent of oxidation of the titanium nitride conductive layer is correlated with the increase of surface roughness. The extent of water decomposition is correlated with formation of hydrogen and oxygen bubbles.

The present invention provides a method of forming an electrode having reduced corrosion and water decomposition on a surface thereof. A conductive layer is deposited on a substrate. The conductive layer is partially oxidized by an oxygen plasma process to convert a portion thereof to an oxide layer thereby forming the electrode. The oxide layer is free of surface defects and the thickness of the oxide layer is from about 0.09 nm to about 10 nm and ranges therebetween, controllable with 0.2 nm precision.

The present invention provides a nano-fluidic field effective device. The device includes a channel having a first side and a second side, a first set of electrodes adjacent to the first side, a second set of electrodes adjacent to the second side, a control unit for applying electric potentials to the electrodes and a fluid within the channel containing a charge molecule. The first set of electrodes is disposed such that application of electric potentials produces a spatially varying electric field that confines a charged molecule within a predetermined area of said channel. The second set of electrodes is disposed such that application of electric potentials relative to the electric potentials applied to the first set of electrodes creates an electric field that confines the charged molecule to an area away from the second side of the channel.
摘要:
A nanodevice includes a reservoir filled with a conductive fluid and a membrane separating the reservoir. The membrane includes an insulating layer. A nanopore is formed through the membrane, and an organic coating is provided on the insulating layer to form a transient bond to a DNA molecule in the nanopore. The transient bond is stronger than thermal motion, such that the transient bond can hold the DNA molecule against the thermal motion. When a voltage is applied across the membrane, the voltage will break the transient bond to move the DNA molecule through the nanopore in a controllable state.

A nanodevice is provided. A reservoir is filled with an ionic fluid. A membrane separates the reservoir, and the membrane includes electrode layers separated by insulating layers in which the electrode layers have an organic coating. A nanopore is formed through the membrane, and the organic coating on the electrode layers forms transient bonds to a base of a molecule in the nanopore. When a first voltage is applied to the electrode layers a tunneling current is generated by the base in the nanopore, and the tunneling current travels through the transient bonds formed to the base to be measured as a current signature for distinguishing the base.
