Methods of addressing a biomolecule to a selectively addressable electrode are described. A permeation layer overlying a plurality of selectively addressable electrodes is provided. The permeation layer includes a reactive group that is adapted to bond to a biomolecule and that requires activation through a chemical transformation before bonding to the biomolecule. At least one selectively addressable electrode is biased such that a pH change occurs in an overlying solution of the at least one selectively addressable electrode. The reactive group in a portion of the permeation layer above the at least one selectively addressable electrode is then chemically transformed to an activated reactive group as a result of the pH change. A biomolecule is then bound to the permeation layer overlying the at least one selectively addressable electrode through the activated reactive group.

Biomolecular attachment sites on microelectronic arrays and methods thereof

Microreaction molds and methods of molding very thin films onto substrate surfaces are provided. The molds and molding methods allow for consistency and uniformity in the thicknesses of the films that are applied to the substrate surfaces. The molds may be single composite, such as etched silica, or multicomposite, such as quartz/metal. The molds may further comprise an adjustable molding cavity. The molds of this invention are particularly applicable to generating thin polymeric films onto microchip substrates.
