Abstract:
1. A fluorescence detection apparatus comprising: a substrate having a surface on which fluorescently labeled biomolecules are immobilized; a sample holding unit that holds said substrate; at least one light source that irradiates the substrate with light so that an evanescent field is produced from said substrate; a prism disposed on an optical path of the light from said light source, said substrate and said prism being separated from each other; a light dividing unit that divides light emitted from said biomolecules for each wavelength; a sensor that detects the light divided by said light dividing unit; and a controller that processes the light detected by said sensor, wherein said prism includes a unit that retains matching liquid to form a liquid layer of said matching liquid in which said substrate is immersed.
