摘要:
Microarrays are provided that include multiple analysis areas. Each analysis area can include first and second active areas, and first and second hydrophobic areas. The first hydrophobic area surrounds the first active area, and the second active area surrounds the first hydrophobic area. The microarrays are useful in analytical chemistry, biochemistry and biology.
摘要:
A bio-sensor that includes (a) an optical fiber in which the surface of the fiber comprises a hydrogel polymer that includes a functional group comprising a first member of a binding pair; and (b) an excitation light source coupled to the fiber. When the fiber contacts a solution comprising a second member of the binding pair labeled with a light-emitting label, the first member binds to the second member, resulting in the emission of a detectable signal. Alternatively, the first member of the binding pair is provided with the light-emitting label.

摘要:
In various embodiments, chromophores are described that include novel electron acceptors, novel electron donors, and/or novel conjugated bridges that are useful in nonlinear optical applications. In some embodiments, the present invention provides chromophore architectures wherein a chromophore contains more than one electron acceptor in electronic communication with a single electron donor, and/or more than one electron donor in electronic communication with a single electron acceptor. Also described is processes for providing materials comprising the novel chromophores and polymer matrices containing the novel chromophores. Electro-optic devices described herein contain one or more of the described electron acceptors, electron donors, conjugated bridges, or chromophores.
摘要:
The present invention provides hyperpolarizable organic chromophores. The chromophores are nonlinear optically active compounds that include a π-donor conjugated to a π-acceptor through a π-electron conjugated bridge. Macromolecular structures including the hyperpolarizable organic chromophores are also provided.
摘要:
