Abstract: In detection of a test substance including a biomolecule by utilizing photocurrent detection of dye sensitization, disclosed is a detection method in which process of the photocurrent detection is carried out by using an electrolyte solution not necessarily requiring an organic solvent. By making the electrolyte medium an aqueous system not containing an organic solvent, not only its usability can be enhanced but also measurement values with less dispersion can be obtained. Therefore, detection of the test substance including a biomolecule by utilizing the photocurrent detection of dye sensitization according to the present invention is characterized by that the processes from a reaction process of a test substance till detection of the photocurrent are carried out in a single apparatus, and that process of the photocurrent detection is carried out by using an electrolyte solution not necessarily requiring an aprotic solvent.
