Recently, asthma has begun to be regarded as basically airway inflammatory reaction. Therefore, as a therapeutic method for asthma, drug therapy represented by inhaled corticosteroid has been recommended. As an index of airway inflammatory conditions, nitric oxide in the breath has attracted attention. The amount of nitric oxide (NO) in the breath correlates with the degree of airway inflammation, and by monitoring the amount of nitric oxide in a certain period of time, the degree of airway inflammation can be monitored. For example, JP-A-2012-18182 (PTL 1) discloses a device which detects the amount nitric oxide in the breath.
However, the degree of airway inflammation may be improved temporarily immediately after a drug such as inhaled corticosteroid is inhaled. Due to this, when a nitric oxide concentration in the breath is measured immediately after a drug such as inhaled corticosteroid is inhaled, the nitric oxide concentration which correctly reflects the true degree of airway inflammation cannot be measured, and therefore, highly reliable information may not be able to be obtained.
An advantage of some aspects of the invention is to provide a nitric oxide concentration testing device, a nitric oxide concentration testing system, a nitric oxide concentration testing server, a nitric oxide concentration testing terminal device, and the like, each capable of obtaining highly reliable information.

The detection section 11 according to this embodiment detects the nitric oxide concentration using spectroscopy. More specifically, the detection section 11 detects the nitric oxide concentration using a surface-enhanced Raman scattering method.
Next, a sensor chip 300 which constitutes part of the detection section 11 will be described.
As shown in
The substrate 130 is, for example, a glass substrate, a silicon substrate, or a resin substrate.
The metal microstructure 132 is provided on the substrate 130. The shape of the metal microstructure 132 is not particularly limited, and is, for example, a cylinder, a particle, a prism, a sphere, or a spheroid. The size (for example, the diameter) of the metal microstructure 132 is equal to or smaller than the wavelength of light irradiated on the sensor chip 300. Specifically, the size of the metal microstructure 132 is 40 nm or more and 700 nm or less. In the example shown in the drawing, a plurality of metal microstructures 132 are provided. The material of the metal microstructure 132 is, for example, gold, silver, aluminum, or copper. The metal microstructure 132 is formed by, for example, a vacuum deposition method or the like.
When the metal microstructure 132 is irradiated with light, surface plasmon resonance (SPR) occurs. Specifically, in the metal microstructure 132, localized surface plasmon resonance (LSPR) occurs. LSPR is a phenomenon in which when light is incident on a metal structure with a size equal to or smaller than the wavelength of the light, free electrons present in the metal collectively oscillate due to an electric field component of the light, and a local electric field is induced outside. By this local electric field, Raman scattered light can be enhanced. A phenomenon in which Raman scattered light is enhanced by an electric field induced by SPR in this manner is referred to as “electric field enhancement effect”. The intensity of Raman scattered light enhanced by SPR (SERS light) is proportional to the fourth power of the electric field enhanced by SPR.
The organic molecular modification film 134 is provided on the metal microstructure 132. The organic molecular modification film 134 includes a modifying molecule according to this embodiment (hereinafter also simply referred to as “modifying molecule”). The modifying molecule is disposed on the surface of the metal microstructure 132. The organic molecular modification film 134 is formed by, for example, immersing the substrate 130 having the metal microstructure 132 formed thereon in a solution in which the modifying molecule is diluted (for example, at a concentration of 1 mM) for a long time (for example, 24 hours), and thereafter, taking out the substrate 130 from the solution and blowing off water.
The modifying molecule is derived from, for example, a compound having an amine-based functional group. Specifically, the modifying molecule is derived from aniline which is a benzene ring having an amine group (see the following formula (1)). In this case, the modifying molecule binds to the metal microstructure 132 through the amine group as shown in
The modifying molecule may be derived from a compound which has a sulfur-based functional group instead of having an amine-based functional group. Specifically, the modifying molecule may be derived from methanethiol (CH3SH). Here, the phrase “derived from a given compound (for example, aniline or methanethiol)” refers to that the compound is bound to the metal microstructure 132 through a bond such as a coordinate bond, a covalent bond, an ionic bond, or a hydrogen bond as it is or by detaching part of a substituent, whereby the modifying molecule is obtained.
According to this embodiment, the nitric oxide concentration is detected using spectroscopy, and therefore, the nitric oxide concentration testing device 1, the nitric oxide concentration testing system 2, the nitric oxide concentration testing terminal device 3, the nitric oxide concentration testing system 2a, and the nitric oxide concentration testing terminal device 3a, each of which has excellent measurement reliability, can be realized.
Further, according to this embodiment, the nitric oxide concentration is detected using a surface-enhanced Raman scattering method, and therefore, the nitric oxide concentration testing device 1, the nitric oxide concentration testing system 2, the nitric oxide concentration testing terminal device 3, the nitric oxide concentration testing system 2a, and the nitric oxide concentration testing terminal device 3a, each of which is less likely to be affected by the environment, and is highly sensitive and small in size can be realized.
Hereinabove, the embodiments and modifications have been described, however, the invention is not limited thereto and can be implemented in various modes without departing from the gist of the invention.
The invention includes substantially the same configurations (for example, configurations having the same function, method, and result, or configurations having the same object and effect) as the configuration described in the embodiment.
