<p><P>PROBLEM TO BE SOLVED: To provide a chip structure used in a surface plasmon enhanced fluorescent device, capable of being configured to eliminate the need for a lens, and preventing the lowering of an S/N value caused by the lowering of condensing efficiency regardless of low cost. <P>SOLUTION: In the chip structure used in the surface plasmon enhanced fluorescent device having a metal membrane receiving the irradiation with exciting light on one side to be enhanced in electric field, the reaction part formed on the other side of the metal membrane to excite a fluorescent substance by the enhanced electric field, and a substrate comprising a fluorescence pervious base material and having a flow channel for sending a liquid using the reaction part as a base by joining the surface having a flow channel groove formed thereto to the surface of the metal membrane, the cavity groove surrounding the periphery of the reaction part to upwardly extend is provided to the substrate centering the reaction part and fluorescence can be reflected from the boundary surface of the cavity groove and the substrate. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
