Title:
DETECTOR AND ELECTRONIC EQUIPMENT
Document Type and Number:
Japanese Patent JP2014190912
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a detector and electronic equipment in which, even when a refractive index of a medium around a metal nanostructure varies by adsorption to the metal nanostructure to shift a plasmon resonance wavelength from a designed value, an optical path length of a resonator can be changed in accordance with the shift amount.SOLUTION: A detector 20A, 20B for detecting a target molecule included in a fluid sample includes: a sensor substrate 10A to 10C; a light source 30 which irradiates the sensor substrate with light to induce surface enhanced Raman scattering; and a photodetector 50 which detects surface enhanced Raman scattering light. The sensor substrate includes: a mirror layer 14; a light-transmitting layer 16 disposed on the mirror layer and including a layer 16A where an optical path length changes by application of an electric field; and a plurality of metal nanostructures 18 disposed on the light-transmitting layer.
