response of nano-TiO2 film, a urease/nano-TiO2 complex films electrode was developed. The results show that the activity of urease can be enhanced by being adsorbed on nanostructure materials, and the Michaelis-Menton constant of free and urease adsorbed on different particles sizes of TiO2 (5 nm, 25 nm, 2.4 μm) are 0.45, 0.22, 0.28 and 0.31 mol/L, respectively. The complex films electrode......
