  • Publication number: 20130109779
    Abstract: Polymeric and co-polymeric compositions useful for preparing ophthalmic and ocular devices, such as implantable intraocular lenses (IOL) and contact lenses, and processes of forming the compositions and devices are provided. The disclosed polymeric or co-polymeric composition may include a curcuminoid compound as a UV-blocker, and is derived from a pre-polymerization mixture of monomers which comprises at least 50 weight percents acrylate monomers and exhibiting visible light transparency and ultraviolet light opacity. The disclosed co-polymeric composition may alternatively, or in addition, be derived from a pre-polymerization mixture of defined monomers.

  • Patent number: 5547702
    Abstract: A method for making a test strip is described. The test strip is generally a substrate, a layer disposed on the substrate and located near the distal end of the substrate. The layer typically contains a chemical reagent detection system capable of detecting the presence of a predetermined analyte in a sample of biological fluid, wherein the reagent detection system produces a detectable change in the layer in the presence of the analyte.

  • Patent number: 4952515
    Abstract: A method for the detection of a predetermined substance in a fluid is described. The method uses a test strip that is stable to storage and accelerated keeping test conditions. A sample of a fluid containing an unknown quantity of a predetermined substance is contacted with a support having thereon a reagent layer wherein the reagent layer contains a dialyzed latex polymer and a reagent detection system which reacts with the substance to provide a detectable change. The detectable change can be determined qualitatively or quantitatively to determine the presence or the amount of the predetermined substance.
