ABSTRACT
Objective To construct a kind of novel electrochemical glucose biosensor for clinical detection.Methods Multiwall carbon tube(MWCNTs),NanoAu and glucose oxidase(GOD) were immobilized on the Au electrode by monolayer self-assemble.Cyclic voltammetry and linear scan voltammetry were used to investigate the assembling process and the chemical characteristics of the glucose biosensor.Results The linearity of glucose in the range of 10~1 400 mg/L with the correlation coefficient of R2=0.990 9 was obtained by linear scan voltammetry and the detection limited reached 0.000 1 mg/L.The four criterion samples were measured with 3 different biosensors in same conditions and the RSD
