Abstract

Terahertz chemical microscope was carried out to visualize the distribution of the redox reaction of the immobilized-enzyme. The urease films with the spot size of 3, 2, 1 mm in diameter were immobilized on a SiO2/Si/ Sapphire layered device and the laser-excited terahertz radiation from the Si layer was observed, which can be related to the chemical potential shift of the SiO2 surface. The redox reaction between the urease and the urea solution was successfully measured.
