A method of evaluating the physiological activity of an external stimulus on vital cells with the use of a surface plasmon resonance device, characterized in that the physiological activity of the external stimulus on the cells is evaluated by using, as an indication, a second signal appearing after a first signal observed upon the exposure of the vital cells to the external stimulus. By using this method, the physiological activity level of an external stimulus on vital cells can be accurately evaluated. |
