The present application relates to polymer compositions that provide barrier properties to oxygen, water vapor and/or hydrocarbons, to polymer film or sheet comprising the polymer composition and to their use in the manufacture or preparation of plastic material and/or plastic packaging. The present application also relates to a method of reducing oxygen water vapor and/or hydrocarbons permeability in plastic material and/or plastic packaging.

Barrier polymer compositions

A composition of matter having oxygen scavenging properties comprises a blend of a base polymer, a butadiene polymer, and titanium dioxide in an amount sufficient to catalyze reaction of oxygen with the butadiene polymer. In further aspects, methods for making the compositions herein and packaging film structures comprising the compositions herein, and packaging articles formed of the same, are also provided.

Titanium dioxide catalyzed butadiene polymer based oxygen scavenging system

An assay device is provided for use in determining the presence of a target analyte in a sample. The assay device comprises a solid platform comprising a fibrous mat, the solid platform impregnated with a first FRET chromophore. An antibody-FRET chromophore conjugate is immobilized on a surface of the solid platform, wherein the antibody-FRET chromophore conjugate comprises an antibody affixed to a second FRET chromophore. The first FRET chromophore and the second FRET chromophore are selected to provide an energy transfer from one to another when located within a F&#xf6;rster distance with respect to each other, thereby forming a FRET donor-acceptor chromophore pair. In a further aspect, a method of detecting a target analyte in a sample is provided. In yet a further aspect, packaging sheet materials and packaging articles employing the assay device under certain conditions are provided.
