SAMPLE-HOLDING CARRIER AND FLUORESCENCE DETECTION DEVICE USING SAME

摘要

[Summary] There is provided a sample-holding carrier that can efficiently irradiate a sample in a well with light and a fluorescence detection device using the same. [Object] A biosensor substrate (1) includes: a base substrate (11) to which excitation light is entered from an under face; a reflective film (16) disposed on the top face side of the base substrate (11) and having electrical conductivity; a plurality of wells (13) disposed on the top face side of the reflective film (16) and having a bottom face portion (13a); and a conductive ring (15) that applies a voltage to the reflective film (16) from the outside. When a sample prepared by applying fluorescence labeling to red blood cells is accommodated in the wells (13), the red blood cells are uniformly arranged on the bottom face portion (13a) by applying a positive voltage to the reflective film (16) because the red blood cells are generally negatively charged. Thus, it is possible to efficiently irradiate individual red blood cells with excitation light.
