- the sensitivity of the nanomechanical sensor to water can be reduced to a low value by using a material having low hygroscopicity as a receptor of the nanomechanical sensor.
- the present invention has been completed on the basis of this. As a result, even if a sample containing a large amount of water is measured, even if the output of the nanomechanical sensor is saturated or does not reach saturation, the large output by water affects the value of the detection signal of other trace components.
- the adverse effect of water with a large content such as giving or masking the detection signal of a trace component, can be alleviated.

- the self-assembled film is coated on the sensor surface to enhance the affinity with the low hygroscopic receptor material, that is, the adhesion between such receptor material and the sensor body surface can be achieved by the self-assembled film. It is also possible to strengthen by For such purpose, it is desirable that the components such as binders mixed in the receptor material and the film to be interposed between the sensor surface and the receptor layer itself have low hygroscopicity.
- the sample is applied to multiple nanomechanical sensors and based on the outputs obtained in parallel from these nanomechanical sensors Analysis can also be performed.
- the receptor layer used for each nanomechanical sensor usually uses a different receptor material, but all of the receptor layers used It is not essential that it be low hygroscopic. That is, when identifying a sample or quantifying a component from outputs from a plurality of nanomechanical sensors, for example, data processing such as principal component analysis or machine learning, or the like is performed on a large number of outputs from these sensors. It is proposed that analysis is performed using the following (Non-Patent Document 2, Patent Document 3).
- Such methods may vary depending on the material of the receptor actually used, the type and amount of components contained in the sample, and various other factors, but depending on the situation, some nanomechanical sensors may be used.
- the analysis can be performed with the required accuracy by using only low hygroscopic ones for the.
- a receptor with low hygroscopicity It is usually considered preferable to use.
- high moisture absorption is possible, in any case where the receptor is completely saturated by the moisture in the gas to be measured or the output by the component to be detected can hardly be detected by masking caused by absorbed water.
- Such multi-channel nanomechanical sensors can be configured as a plurality of nanomechanical sensors formed on a single substrate.
- Patent Document 1 and the like describe forming a plurality of MSS on a single silicon substrate.
- a highly hygroscopic receptor that responds specifically to water as the receptor layer of one channel in a multichannel nanomechanical sensor, it is substantially the same as the other components in the sample flow path It is possible to simultaneously measure the amount of water vapor (humidity) of the sample under the same measurement conditions as other components at the same place. That is, it becomes possible to embed a humidity sensor in a multi-channel nano mechanical sensor.
- a highly hygroscopic receptor although it is not limited to this, for example, carboxymethyl cellulose exemplified above can be used.
- this type of effect may have one or more other receptor layers (high hygroscopicity, low hygroscopicity, or a combination thereof) originally intended for use in the detection of other components.
- the output from the channel can be compensated by using machine learning or other techniques.
- the nanomechanical sensor detects changes in physical parameters caused by adsorption of some analyte molecules by the receptor layer by means of the sensor body. Therefore, the sensor body that can be used in the present invention is particularly the structure, operation, etc., if the receptor layer coated on the surface detects changes caused to the receptor layer by adsorbing the analyte. It is not restricted. For example, when a surface stress sensor is used, the surface stress sensor outputs a signal by detecting the stress change caused in the receptor layer by adsorbing the analyte by the receptor layer coated on the surface. .
- Patent Document 1 various surface stress sensors described in Patent Document 1 can be mentioned as an example of a sensor body covered by a receptor layer, but the shape, material, size, etc. are not particularly limited, and any object may be used. It can be used.

- a coating with a self-assembled film or a mixture with other polymers can be used as a receptor layer.

- Polycaprolactone Product No. 440752-250G
- Polyvinylidene Fluoride Product No. 427152-100G
- Poly 4-methylstyrene Product No.
- the solution was applied onto the sensor body (in this example, the MSS body, that is, the sensor chip) by inkjet. At this time, the sensor chip was heated to 80 ° C. in order to accelerate the drying of the coating solution.
- the sensor chip was heated to 80 ° C. in order to accelerate the drying of the coating solution.

Specifically, the upper left channel had 100 shots, the upper right channel had 200 shots, the lower left channel had 300 shots, and the lower right channel had 400 shots. Photomicrographs of the sensor after application are shown in FIGS. 1A-1D.

- the above sample is divided into vials, and a certain amount of sample accumulated in the head space portion of the vial by flowing nitrogen as carrier gas controlled to a flow rate of 100 mL / min by the mass flow controller (MFC 1). It was introduced into a sealed chamber containing a sensor as a headspace gas containing steam. Here, the sample vapor was obtained at room temperature. Another mass flow controller (MFC2) was prepared and operated under the same conditions. However, this was connected to an empty vial and then connected to the sensor chamber to introduce nitrogen without sample vapor. This promoted volatilization of the sample adsorbed to the receptor layer, and the receptor layer was washed.
- the above sample introduction and washing cycle was repeated four times at 30 second intervals. More specifically, the cycle consisting of a 30 second sample introduction and a 30 second wash was repeated 4 times (total 240 seconds).
- FIGS. 3A to 3D The measurement results when using polysulfone, polycaprolactone, polyvinylidene fluoride, and poly 4-methylstyrene coated MSS are shown in FIGS. 3A to 3D, respectively.
- the measurement result using carboxymethylcellulose coated MSS of a comparative example is shown to FIG. 3E.
- the thickness of the coating (receptor layer) of MSS shown in FIGS. 1A to 1E increases in the order of upper left ⁇ upper right ⁇ lower left ⁇ lower right, but in the graphs shown in FIGS. 3A to 3E
- the output from MSS was displayed in a superimposed manner. With either receptor, it was found that as the layer thickness increased, the power also increased. As the thickness of the layer increases, the stress obtained as a whole also increases, and as a result, the increase in the output has been analytically confirmed.
- Non-patent document 4 The thickness of the coating (receptor layer) of MSS shown in FIGS. 1A to 1E increases in the
- Output signals for the water, n-hexane, methanol and acetone vapors of the polysulfone, polycaprolactone, polyvinylidene fluoride, and poly 4-methylstyrene coated MSS which are examples of the present invention (shown in the graphs of FIGS. 3A to 3D, respectively)
- the output signal for water is quite small. Therefore, the receptor layer formed of low hygroscopic material has very low water absorption, and therefore absorbs a large amount of water to give a change of the MSS output signal even if it gives high humidity sample gas It is naturally prevented and suppressed to saturate the change in physical quantity and to prevent the adsorption of components other than water.
- the small output signal from the MSS due to other trace components is buried in the large output signal from the MSS caused by water and is also prevented from being masked.
- the output signals for the other three vapors, hexane, methanol and acetone are very different depending on the material of the receptor. Also, from the output signal for methanol, it can be seen that the output signal when using a receptor layer formed of a low hygroscopic material is not always small just because it is a water-soluble solvent .
- FIG. 3E is a graph of the output signal from the MSS that formed the receptor layer with carboxymethylcellulose as measured as a comparative example
- the output signal for water is very large, but the other three
- the output signal for the type of steam is very small compared to the case of water.
- MSS using a receptor layer formed from such a material even if there is a substance that specifically outputs a large signal other than water, the receptor layer is given a gas of high humidity. By absorbing a large amount of water and causing a large swelling, the output signal of the MSS becomes saturated or the like, which makes the detection of the substance impossible or difficult.
- these characteristics can be said to be capable of measuring the humidity with high accuracy while eliminating the influence of the contaminating components as much as possible.
