Abstract:
A method of treating a substrate for immobilizing a biomolecule and substrates produced by the method are disclosed. The method includes contacting at least a portion of a substrate with a reducing agent such as a hydride. Treatment with an appropriate reducing agent substantially eliminates autofluorescence on substrates.
Abstract:
A polyester having less than 50 hydrogen-carbon bonds per 1000 molecular weight units exhibits very low optical loss in the range of wavelengths commonly used for optical communication, and exhibits other physical properties suitable for use as a waveguide core material and/or a waveguide cladding material in optical fibers and/or planar optical devices.
Abstract:
The present invention is directed to chromophores having novel electron withdrawing groups and novel bivalent cyclic bridges and to optical waveguides and optical devices having polymeric thin films which contain the novel chromophores.

Abstract:
The present invention relates generally to mercaptofunctional high μβ EO chromophores and EO polymers, and particularly to mercaptofunctional high μβ EO chromophores and EO polymers useful for making electro-optical devices and systems. Mercaptofunctional high μβ EO chromophores are covalently bonded to poly(imido sulfide) polymers producing high Tg, low optical loss, covalently bonded, high μβ EO chromophore containing polymers. Methods of synthesizing these EO materials using mild polymerization conditions are also described.
