摘要:
A method for detecting the presence of target molecules bound to a working electrode in a first location. The first location is coated with a detection solution containing labeling molecules that include a first charge-separation moiety attached to a first molecule that binds to the target molecule. The first charge-separation moiety includes a material that generates hole-electron pairs in response to being illuminated by light in a first band of wavelengths. After removing any unbound labeling, the working electrode is immersed in a solution containing a compound that is oxidized by the generated holes. The first location is then selectively illuminated with light in the first band; and the change in the current and/or potential is measured between the working electrode and a reference electrode in contact with the solution. The first charge-separation moiety is preferably constructed from particles of a semiconducting material such as TiO2.

A precursor according to the present invention includes a plurality of electrochemical polymerizable monomers, each monomer having first and second polymer-forming active sites that can be joined by electrochemical polymerization. The monomers also include third and fourth polymer-forming active sites that can be joined chemically in solution. The monomers in the precursor polymer are linked by the third and fourth polymer-forming active sites. The monomers are chosen such the precursor polymer is soluble in a predetermined solvent while the polymer resulting from the electrochemical polymerization of the precursor polymers via the first and second polymer-forming sites is electrically conducting and insoluble in the solvent. The monomers can be synthesized from fluorene, triophene, pyrrol, biphenyl, poly(vinyl carbazole) or poly (vinyl oxy thiophene). Monomers comprising dimers chosen from this group can also be utilized. The monomers may also include a spacer group bonded to one of the first or second polymer-forming active sites. Spacer groups consisting of (CH2)n, (OCH2)n, or (OCH2CH2)n, where 1≦n≦20 may be utilized for this purpose.

A display device and a method for fabricating the display device. A display device according to the present invention is fabricated from an electrode layer that includes a plurality of electrodes on a substrate. The electrode layer is immersed in a solution of a first precursor polymer in a first solvent. The first precursor polymer includes a plurality of electrochemical polymerizable monomers. Each monomer has first and second polymer-forming active sites that can be joined by electrochemical polymerization and third and fourth polymer-forming active sites that can be joined chemically in solution. The first precursor polymer is soluble in the first solvent whereas a first polymer formed by electrochemical polymerization of the first and second polymer-forming active sites is insoluble in the first solvent. A layer of the first polymer is deposited on the a first one of the electrodes by connecting that electrode to an electric circuit while leaving the others of the electrodes disconnected from the circuit. The electrode is then immersed in a solution of said first precursor polymer. The circuit applies a potential to the electrode sufficient to cause the first and second polymer active sites to polymerize by electrochemical polymerization thereby depositing a first polymer layer includes the first polymer precursor on the first one of the electrodes. A second electrode layer is then deposited over the first polymer layer. In multi-color displays, the different polymer layers corresponding to the various colors are deposited on different ones of the electrodes by sequentially depositing each polymer layer in a similar manner.

The present invention is a film and method for making the same. The film includes a plurality of particles having a desired film property that are entrapped in a matrix of linkage polymer molecules. The linkage polymer molecules ionically bind to the particles. The linkage polymer molecules are electrochemically polymerizable in a solvent. The particles are insoluble in the solvent. The film is prepared by providing an electrode and a solution of the linkage polymer molecules in which the particles are suspended. An electrical potential is provided between the solution and the electrode in temporal sequence that causes the linkage polymer molecules to polymerize in the vicinity of the electrode thereby entrapping the particles.
