METHOD TO IMPROVE SENSITIVITY OF SURFACE PLASMON RESONANCE SENSOR, PRODUCE SURFACE PLASMON RESONANCE SENSOR AND APPLY THEREOF

摘要

PURPOSE: A method for improving the sensitivity of a surface plasmon resonance sensor and a manufacturing method and an application method for a surface plasmon resonance sensor are provided to improve the sensitivity of a surface plasmon resonance sensor by employing a metal-dielectric composite with a relatively large surface plasmon wave vector. CONSTITUTION: An application method of a surface plasmon resonance sensor is as follows. A metal-dielectric composite for generating surface plasmon resonance by incident light of specific wavelength is analyzed. A metal volume mixing ratio P which has different surface plasmon wave vectors according to the dispersion property of the analyzed metal-dielectric composite is determined. A metal-dielectric composite material in a single film shape that is regularly or irregularly mixed at a determined metal volume mixing ratio P is manufactured. A surface plasmon resonance sensor chip is manufactured out of the metal-dielectric composite material. While maintaining the fixed wavelength of incident light, a sensor chip having a different surface plasmon wave vector is replaced to adjust the effective permittivity and sensitivity of the plasmon resonance sensor.
