An object of the present invention is to provide a method for securing the mobility of immobilized molecules, suppressing nonspecific adsorption, and enabling strict interaction kinetics analysis. A biomolecule is immobilized on a solid surface using a heterobifunctional hydrophilic polymer as a crosslinking agent, and the interaction between the immobilized biomolecule and the biomolecule or biomolecule aggregate is measured. A biomolecule interaction measurement method comprising the step of: [Selection diagram] FIG. |
