Problems solved by technology

[0010] However, in the configuration described in Patent Document 1, there is no optical system that introduces the isotropic emission light from the organic molecular probe into the solid-state imaging element, which results in a system that cannot obtain a sufficient amount of light and has low sensitivity and precision. question

[0068] A chemical substance detecting device according to a first embodiment of the present technology will be described below.

[0069] [Overall structure of chemical sensor]

[0070] figure 1 is a plan view of the chemical sensor 1 according to the present embodiment, figure 2 is a cross-sectional view of the chemical sensor 1 . As shown in these figures, the chemical sensor 1 includes a light guide 3 provided on a substrate 2 and a peripheral circuit provided on the substrate 2 . A plurality of photodetectors 21 are disposed on the substrate 2 , and the light guide 3 is disposed on the plurality of photodetectors 21 .

[0071] As will be described in detail later, the light guide 3 supports the tracer material, and the target material (detection object) contained in the supplied sample is bound to the tracer material. Light (fluorescence, etc.) generated from the combination including the target material and the tracer material enters the photodetection section 21 prov...

Abstract

[Problem] To provide a chemical sensor, which is capable of efficiently detecting light emission of a subject to be detected, a chemical sensor manufacturing method, and a chemical material detecting apparatus. [Solution] A chemical sensor relating to the present technology is provided with a substrate and a lens layer. At least one light detecting section is formed on the substrate. The lens layer is laminated on the substrate, has light transmitting characteristics, and has a lens structure formed on the surface on the reverse side of the substrate, said lens structure having a recessed shape in the laminating direction.

Description

technical field [0001] The present technology relates to a chemical sensor that detects a chemical substance using light emitted from a detection object, a method of manufacturing the chemical sensor, and a chemical substance detection device. Background technique [0002] Chemical sensors that detect chemical substances using emitted light due to chemical binding have been studied. Specifically, a tracer material that specifically binds to a target material to be detected is immobilized on a sensor, and a sample is supplied to the sensor. Thus, the target material contained in the sample binds to the tracer material. For example, if the combined body is made to emit light using a fluorescent label that can be introduced into the combined body including the target material and the tracer material, the photoelectric conversion element can detect the emitted light. By immobilizing multiple tracer materials on the sensor, it is also possible to identify the species of target ...
