FLUORESCENT SENSOR AND SENSOR SYSTEM

摘要

A fluorescent sensor includes a detecting substrate, an indicator, a filter layer, a light blocking layer, and an LED chip. In the detecting substrate, a PD element for converting fluorescence into electric signals is positioned on wall surfaces of a through-hole which penetrates a first main surface and a second main surface. The indicator is arranged inside the through-hole and generates fluorescence of intensity corresponding to analyte density when the indicator receives excitation light. The filter layer covers the PD element, transmits fluorescence and blocks excitation light. The light blocking layer, through which an analyte can pass, covers an opening of the first main surface of the through-hole. The LED chip covers a region just below an opening of the second main surface of the through-hole, and generates excitation light.

1. A fluorescent sensor, comprising:
a detecting substrate possessing a first main surface, a second main surface, and a through hole, the through-hole penetrating the first and second main surfaces; a photoelectric conversion element configured to convert fluorescence into an electric signal positioned in a wall surface of the through-hole; an indicator arranged inside the through-hole and configured to generate the fluorescence of intensity corresponding to an analyte density when the indicator receives an excitation light; a filter layer covering the photoelectric conversion element and configured to transmit the fluorescence and block the excitation light; a light blocking layer covering an opening of the first main surface of the through-hole, the analyte passing through the light blocking layer; and a luminous element chip covering a region below an opening of the second main surface of the through-hole and configured to generate the excitation light.
