Abstract
We have developed a new chemical-imaging sensor, which can visualize the two-dimensional distribution of a specific substance. This sensor uses an enzyme immobilized on the sensing surface of the pH-imaging sensor that we reported previously. As an example, a urea-imaging sensor has been fabricated using urease, and some two-dimensional patterns of urea distribution in agar visualized.
