Abstract

The invention discloses a nanometer gold catalysis resonance scattering spectrum method for testing amylaceum, which is based on the catalysis of nanometer gold on the copper bromide particles generated by Cu(II)-amylaceum-KBr, and the linear relationship between amylaceum in some density and delta I610nm. The invention has the advantages that compared with prior art, the invention combines catalysis reaction with resonance scattering spectrum technique, with high analysis sensitivity, low check limit, ug/mL level, better selectivity, simple operation, simple device, easily accessible agents and low cost, which only needs fluorescence spectrometer.

Description

Technical field: [0001] The invention relates to a method for measuring glucose, in particular to a nano-gold catalyzed resonance scattering spectrometry for measuring glucose. Background technique: [0002] Glucose is an indispensable substance in life activities. It can directly participate in the metabolic process in the human body. In the digestive tract, glucose is easier to be absorbed than any other monosaccharide, and after being absorbed, it can be directly used by human tissues. It has the functions of replenishing body fluids, Supply energy, replenish blood sugar, strengthen the heart and diuresis, promote detoxification, and also have a certain therapeutic effect on cancer. In addition, glucose is also used in printing and dyeing leather, mirror industry and thermos tank silver plating process. At present, the detection methods of glucose mainly include high performance liquid chromatography, enzyme catalysis, Fehling method and so on. The first two methods or ...
