Abstract
The Raman scattering spectroscopic method according to the present invention include: preparing a chip having a channel in which a nanostructure is formed; introducing an analyte solution into a part of the channel in the chip; irradiating an interface of the analyte solution with a laser beam; and measuring Raman scattering light induced by the irradiation of the laser beam. The measurement may be performed, with a fixed laser beam irradiation position, both in a state where the interface of the analyte solution is included in the laser-beam-irradiation area and in a state where the interface of the analyte solution is not included in the laser-beam-irradiation area, or may be performed keeping the state where the interface of the analyte solution is maintained in the laser-beam-irradiation area by controlling the laser-beam-irradiation area according to the movement of the interface due to evaporation of the analyte solution.
