<p><P>PROBLEM TO BE SOLVED: To provide a detection surface for biosensors used for a surface plasmon resonance analysis in which the variations in a signal change at a position in a chip are small. <P>SOLUTION: The biosensor made of a substrate coated with a hydrophobic highly polymerized compound by spincoating has a functional group for immobilizing a physiologically active substance on the uppermost surface on the substrate, and analyzes the interaction between biomoleculars by surface plasmon resonance. The functional group is for example -OH, -SH, -COOH, -COH, -NCO, -NCS, epoxy group, and a vinyl group. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
