METHOD FOR DETECTING OR ASSSAYING TARGET MATERIAL, AND ELECTRODE SUBSTRATE, DEVICE, AND KIT USED FOR THE SAME
First Claim
1. A method for detecting or assaying a target material in a sample solution, comprising:
- a) forming a metal oxide thin film containing a target material model on an electrode substrate;
b) forming, on the metal oxide thin film, a recess into which the target material is able to engage, by removing the target material model from the metal oxide thin film;
c) making the sample solution, into which a redox reactive molecule is added, contact the metal oxide thin film in which the recess is formed; and
d) electrochemically detecting a transition of electron exchange with the redox reactive molecule in the vicinity of the electrode substrate surface, before and after the third process.

Abstract
A method for detecting or assaying a target material in a sample solution, including: a first process for forming a metal oxide thin film containing a target material model on an electrode substrate; a second process for forming, on the metal oxide thin film, a recess into which the target material is able to engage, by removing the target material model from the metal oxide thin film; a third process for having the sample solution, into which a redox reactive molecule is added, contact the metal oxide thin film in which the recess is formed; and a forth process for electrochemically detecting a transition of electron exchange with the redox reactive molecule in the vicinity of the electrode substrate surface, before and after the third process.
