amperometric microbiosensor for the determination of choline

نویسندگان
چکیده

the construction and performance of an amperometric microbiosensor for the determination of choline chloride by immobilizing choline oxidase on a cellulose acetate membrane are described. the procedure of choline determination involved the electrochemical detection of enzymatically generated hydrogen peroxide. this microsensor has a linear response between 0.038-0.1 mm choline chloride. the response time is 1-2 minutes. the optimal working conditions for the microsensor were 0.1 m tris-hcl, ph = 8 at 30°c

Evaluation of Different Functionalized CNTs for Development of Choline Amperometric Biosensor

Choline oxidase (ChOx) was chosen as a model enzyme for evaluating the performance of CNTs’ functional groups for development of enzyme electrodes. CNTs were functionalized with carboxylic acid, amine or amide groups. Carboxylic acid, amine and amide functionalized CNTs were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...

Functionalized conducting polymer as an enzyme-immobilizing substrate: an amperometric glutamate microbiosensor for in vivo measurements.

The functionalized conducting polymer (CP) of 5, 2':5', 2' '-terthiophene-3'-carboxylic acid on a platinum microelectrode was prepared through the electropolymerization process using cyclic voltammetry and was used as a substrate for the immobilization of enzymes. The nanoparticles of the CP were obtained at a high scan rate in the cyclic voltammetric experiment. A needle-type amperometric glut...
