Biological microsystem for measuring uric acid in biological fluids
This paper describes a biological microsystem (bio-system) for measuring uric acid concentration in serum, plasma or urine. Its operation is based on optical absorption in a well-defined part of the visible spectrum. The bio-system is composed by two dies: one is fabricated in polystyrene and contains the microchannels and the other is fabricated in a CMOS standard process and contains the phot...
متن کاملMicromethod for the determination of uric acid in biological fluids.
A micro procedure for estimating uric acid in body fluids, based on the carbonate method, is described. Interferences are elucidated. The stoichiometry of the reaction is carefully worked out. Reliability of the method is established by comparison with two other methods, by recovery experiments, and by replicate analyses.
متن کاملStudies on uric acid and related compounds. I. Quantitative determination of uric acid in biological fluids.
The available methods of determination of uric acid can be divided into three main groups: (a) the direct determination of the reducing power of uric acid; (b) the coprecipitation of the uric acid or its adsorption on a precipitating material, dissolving the acid, and determination of its reducing power; and (c) quantitative decomposition of uric acid by uricase. A survey of these methods has b...
متن کامل[Measuring linezolid in biological fluids using high-efficiency liquid chromatography].
OBJECTIVE Evaluation of an analytic method for determining linezolid concentrations in biological fluids including plasma, vitreous humour and cerebrospinal fluid using high-efficiency liquid chromatography and subsequent ultraviolet detection. METHOD The method was validated by studying the following parameters: accuracy, precision, sensitivity, linearity and recovery. The drug was extracted...
متن کاملThe determination of uric acid in biological materials.
Uric acid is commonly determined in biological fluids by measuring the blue colour produced by its reaction with reagents containing phosphotungstic or arsenotungstic acids under conditions which minimize interference by other reducing substances (Folin & Denis, 1912; Folin, 1933, 1934; Benedict, 1912, 1922; Brown, 1945; Bidmead, 1951). Recovery of uric acid added to blood has never been comple...
