Abstract
An object of the present invention is to detect a small biomolecule in a sample using simple and inexpensive equipment. To achieve this, the small biomolecule in a sample S is detected optically. Specifically, the sample S containing an aptamer capable of interacting with the small biomolecule is irradiated with an excitation light Le and irradiated with a measurement light Lfor measuring the photothermal effect produced in the sample S by the irradiation with the excitation light Le. The photothermal effect induced in the sample S by the excitation light Le is measured from the phase change in the measurement light L, and the presence or absence of the interaction between the biomolecule and the aptamer is assessed based on the temporal variation in the measurement signal.
