Abstract:
The present invention provides a matrix comprising an array of nanostructures that exhibit a variation (gradient) in physical properties (such as size or pitch) in at least one direction of the plane containing said array. A method for forming an array having a gradient property is also provided. In addition, a separation method is provided comprising the steps of: providing a matrix comprising an array of nanostructures arranged so that the array has the property of a gradient; and conducting at least one biomolecule separation process to separate biomolecules in a composition containing a plurality of biomolecules using the matrix.
Abstract:
The invention provides a sensing device comprising: a vessel; a plurality of sensor beads located within the vessel to form interstitial spaces there through; and a plurality of biomolecules bound to at least at portion of the plurality of beads, each of the biomolecules having a fluorescent tag. A sensing device comprised a suspension of a plurality of sensor beads. The invention also provides a method for detecting the binding of two biomolecules comprising the following steps: providing a plurality of first biomolecules, each of the first biomolecules having a first fluorescent tag; and providing a plurality of second biomolecules, each of the second biomolecules having a second fluorescent tag. The binding step have a pre-complexing total fluorescence and detecting any difference between the pre-complexing total fluorescence and the post-complexing total fluorescence.
Abstract:
Method for treating an aluminum alloy surface for electrodeposition or electroless deposition of a metal or alloy on the surface, the surface is oxidized (e.g. anodized) to form aluminum oxide, and then the oxidized surface is chemically etched to render the surface amenable for electrodeposition or electroless deposition of the metal or alloy thereon. A metallic coating can be electrodeposited or electroless deposited on the treated surface.
