    Abstract: A thin film diagnostic device capable of detecting the presence of a specific organic material in a sample solution. The device comprises a layer of an anodizable colour-generating metal (e.g. tantalum), a porous anodic film containing aluminum oxide overlying the colour generating metal, and a reagent capable of binding with the specific organic material forming a coating on the anodic film. The porous anodic film and the coating have a combined thickness such that a colour change is produced when the specific organic material binds to the reagent. The device can be used to test for biological or synthetic products in samples taken from patients or other sources.

    Abstract: An electroluminescent laminate is provided that comprises: a planar phosphor layer (22); a front and a rear planar electrode (14,24) on either side of the phosphor layer; a planar dielectric layer, which is preferably composed of a thick layer (18) and a thin layer (20), between the rear electrode and the phosphor layer, the dielectric layer being formed from sintered ceramic material such that the dielectric layer provides a dielectric strength S which is greater than about 1.0 X 106 V/m and a dielectric constant such that the ratio of the dielectric constant of the dielectric layer to that of the phosphor layer is greater than about 50:1, the dielectric layer having a thickness sufficient to prevent dielectric breakdown during operation as determined by the equation d2 = V/S, wherein d2 is the thickness of the dielectric layer and V is the maximum applied voltage, the dielectric layer forming a surface adjacent the phosphor layer which is sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage, and wherein the dielectric layer is either in contact with the phosphor layer or spaced apart from it by at least one additional layer that is itself in contact with the phosphor layer and wherein the layer that is in contact with the phosphor layer is compatible with the phosphor layer.

    Abstract: A microtitre plate containing a plurality of wells for conducting immunoassays wherein one or more of the sides, bottom and lid walls of each well are formed with a reflective, metallized surface. The surface may be an inner coating on the walls of clear or opaque plates, or an outer coating on the walls of clear plates. Alternatively, the plate may be formed, for example, by stamping from a reflective metal material. Improved sensitivity in photometric detection results from photon emitting immunoassays conducted in the plate.

    Abstract: An improved dielectric layer of an electroluminescent laminate, and method of preparation are provided. The dielectric layer is formed as a thick layer from a sintered ceramic material to provide: - a dielectric strength greater than about 1.0 X 10 6 V/m; - a dielectric constant such that the ratio of the dielectric constant of the dielectric layer to that of the phosphor layer is greater than about 50:1; - a thickness such that the ratio of the thickness of the dielectric layer to that of the phosphor layer is in the range of about 20:1 to 500:1; and - a surface in contact with the phosphor layer which is compatible with the phosphor layer and sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage. The invention also provides for electrical connection of an electroluminescent laminate to voltage driving circuity with through hole technology. The invention also extends to laser scribing the transparent conductor lines of an electroluminescent laminate. 58
