Ruixi Xiaobian recommends Bovine serum albumin - Preparation of platinum composite nano materials ：

Bismuth nitrate aqueous solution was added to the aqueous solution of bovine serum albumin platinum nanomaterials , Mix it with phosphate buffer solution and heat it in water bath , After heating, the mixed solution is ultrafiltered and washed with water to obtain bismuth bovine serum albumin platinum nanocomposites to simulate peroxidase . Bovine serum albumin platinum / Bismuth composite nano materials can simulate peroxidase and catalyze the oxidation of hydrogen peroxide 3,3',5,5' Tetramethylbenzidine hydrochloride color , Yes 3,3',5,5' The Michaelis constant of tetramethylbenzidine hydrochloride is 0.054 mmol/L, The Michaelis constant for hydrogen peroxide is 13.24 mmol/L. At the same time, the simulated enzyme is acid-base resistant , High temperature resistance , High salt tolerance , Excellent room temperature stability .
