Abstract:
1. A process for selectively determining the concentration of homocysteine in a substance, said process comprising the steps of: (a) preparing an aqueous solution comprising a sample of the substance and a dye at a temperature between about 25° C. and about 110° C., and a pH between about 6 and about 8; (b) observing any perturbation in the visible, near infrared, or ultraviolet absorbance spectrum or fluorescence spectrum of the dye; or observing any perturbation in the redox potential of the solution; in either case as compared to the spectrum or redox potential of an otherwise identical and otherwise identically treated solution of the dye that lacks any added homocysteine; and (c) inferring the homocysteine concentration from a previously-determined correlation between observed perturbations in the spectrum or the redox potential of the dye, and the homocysteine concentration;
