Problems solved by technology

[0004] However, so far, there have been fewer examples of analysis of liquid samples using chemical sensors compared to analysis of gaseous samples using chemical sensors, and in particular, little research has been done on the analysis of liquid samples using pattern recognition methods

Embodiment

[0046] Hereinafter, the present invention will be described more specifically based on examples. The following embodiments are examples for making the present invention easy to understand. Please note that the present invention is not limited to specific implementations.

[0047]

[0048] Here, four kinds of acceptor materials are prepared, namely PS (polystyrene, polystyrene), P4MS (poly(4-methylstyrene), poly(4-methylstyrene)), PCL (polycaprolactone, polycaprolactone), PVF (polyvinylidene fluoride, polyvinylidene fluoride) coated MSS, by giving it four kinds of detection gas, namely water vapor, ethanol (ethanol), heptane (n-heptane) and toluene (toluene) to obtain the output signal. The chemical structural formulas of the above four acceptor materials are shown below.

[0049]

[0050] Four polymers used as acceptor materials, PS (Mw=350000), PCL, P4MS and PVF were purchased from Sigma-Aldrich. DMF (N,N-Dimethylformamide, N,N'-Dimethylformamide) used as a solvent use...

Abstract

The present invention addresses the problem of providing a liquid sample analysis method, with which a kinetically slow equilibrium at the liquid-solid interface, which becomes an issue when a liquid sample is analyzed by a chemical sensor, is solved. In the liquid sample analysis method according to one embodiment of the present invention, components to be analyzed in a liquid sample are adsorbed onto a receptor layer of a chemical sensor, one or a plurality of types of gases are then provided to this chemical sensor, and a response thereto is measured. By this, since the slow equilibrium at the liquid-solid interface is not used, high-sensitivity measurement can be performed in a short time, and existing results regarding the analysis of a gas sample on which the study is being conducted can be utilized.

Description

technical field [0001] The present invention relates to the analysis of liquid samples, in particular to an analysis method of liquid samples, which applies the analysis method of chemical sensors such as surface stress sensors for gas samples. The present invention also relates to an analysis device for a liquid sample analyzed by the analysis method. Background technique [0002] For example, in fields such as medicine and biology, identification and analysis of samples are frequently performed. In this case, the target samples are not only gaseous samples but also many liquid samples, and the identification and analysis of liquid samples have different difficulties from those of gases. Most of the currently used biosensors are of a type that detects a target sample on a one-to-one basis, as in detection by an antigen-antibody reaction. In such a detection method, since a very low concentration of biomarkers needs to be detected, known biomarkers need to be detected sepa...
