Latest Patents

One of his latest patents is titled "Method and device employing covalently immobilized colored dyes." This invention describes a test method and device that utilize a matrix to which a second component of a two-component dye system is covalently bonded. The color is formed when the first component, which may be the analyte or another dye component, covalently couples to the second component. The resulting color is covalently immobilized to the matrix. A preferred second component is 5-amino-2-naphthalene sulfonic acid, which forms a colored covalent adduct with oxidized 4-aminoantipyrine. Another preferred second component is diazotized para-aminoaniline, which forms a colored covalent adduct directly with bilirubin.

Another significant patent is the "Method and device for quantitative chromatography." This invention presents an improved chromatographic device and method for quantifying enzyme activity. It utilizes a bibulous test strip as the stationary phase, an aqueous solution as the mobile phase, and a chromophore as the indicator. The enzyme activity is quantified by transforming a chromogenic substrate from soluble chromogen to insoluble chromophore as the mobile phase advances. The resulting insoluble chromophore becomes immobilized on the test strip, producing a column of color. The length and intensity of this color column are directly related to the enzyme's activity.
