<P>PROBLEM TO BE SOLVED: To provide a biomolecule detection device capable of performing high sensitivity measurement. <P>SOLUTION: By irradiating a solution with a laser 117, an external force is applied to free molecules 13 and binding molecules 15 in the solution, and Brownian motion of the free molecules 13 and the binding molecules 15 is inhibited by the external force. By measuring the Brownian motion of the free molecules 13 and the binding molecules 15 in the solution irradiated with the laser 117, a concentration of an antigen attached to the binding molecules 15 can be accurately measured. <P>COPYRIGHT: (C)2012,JPO&INPIT |
