It is intended to provide a bioassay unit, etc. whereby the problem of the space distributionnat the upper part of a detection part can be solved and the servo operation on a discnsubstrate can be stabilized. Namely, it is intended to provide a bioassay unitn(U) which has at least a means wherein a biological substance (a nucleotide chain,na peptide, a protein, a lipid, a low-molecular weight compound, a liposome, etc.)nas a detection subject (D) is fixed in a detection part (3) and , onto the detection subjectn(D) thus fixed, a target-containing solution (S) is dropped so that the detectionnsubject (D) reacts with the target (T) to form a reaction product (R); and anothernmeans wherein the reaction product (R) is irradiated with a excitation lightn(P) of a definite wavelength and the fluorescence (F) thus generated from thenfluorescence-labeled substance (D) is condensed with the use of a lens (5) providednin the back face (102) side of the detection part (3) to thereby detect the intensitynof the fluorescence (F). |
