Embodiment Construction

[0015] A molecular ensemble technique using alternating current (AC) electric fields is disclosed to facilitate selective alignment and migration measurements of electronic nanoscale components. For purposes of this disclosure, the term nano-sized components is intended to include nanoparticles, nanotubes, nanowires, nanorods, synthetic polymers, synthetic molecules, and biomolecules including DNA molecules, proteins, and the like. With proper selection of amplitude and frequency, the use of AC bias significantly enhances the desired nanocomposition ratio location of other contaminant species in solution, for example in solutions containing carbon nanotubes and organic or inorganic contaminants.

[0016] Referring now to FIGS. 1-2 , illustrated in simplified cross-sectional views are component structures for selective alignment of nanometer-sized components in accordance with the present invention and methods of using the structures to provide selective alignment. More specifi...

Abstract

An improved and novel method of selectively aligning and positioning nanometer-scale components using AC fields. The method provides for more precise manipulation of the nanometer-scale components in bridging test electrodes including the steps of: providing an alternating current (AC) field at a single electrode or between a plurality of electrodes to create an electric field in an environment containing nanometer-scale components. The electric field thereby providing for the aligning and positioning of the nanometer-scale components to the desired location.

Description

technical field [0001] The present invention relates to an aggregation technique to facilitate electronic molecular mobility measurements, and more particularly to a method for selective alignment and positioning and aggregation of nanometer-sized components using an alternating current (AC) electric field. Background technique [0002] Molecular electronics is a rapidly emerging field and provides means for overcoming the miniaturization limitations of silicon (Si) technology being researched. Molecular and nano-sized components with unique functionality may be considered as candidates for molecular electronics. One of the problems facing molecular electronics is the transfer of molecular information / functions to the "outside" world. To achieve this goal, a simple and robust process needs to be developed to selectively place and "wire" nanometer-sized components, such as molecules, onto metal electrodes. Rapid screening methods that "bind" candidate molecules to be tested...
