The gas image sensor detects the gas promoted optical changes occurred on the LSPR substrate by CCD camera. Basically, LSPR gas sensor does not have a molecular selectivity, then the identification of gas species is difficult. To overcome the disadvantage, pixelated LSPR substrate based on Au/Ag core-shell structure which has different gas response properties is fabricated by photo-induced metal growth by mask-less exposure system using a commercial video projector.. |

However, the response speed of sensors is now a major limit for the promotion of odor robot using chemical substances information.

However, there are certain difficulties in identifying the type of gas and detecting its concentration by chemical sensors. SERS (Surface Enhanced Raman Scattering) is a promising method for high sensitive gas detection because of its ability of molecule discrimination. However, it is difficult for SERS sensor to identify gases with the similar structure. In this research, we have developed a more selective SERS sensor with molecular filter layers. Molecular filter property is studied by coating a filter polymer film on the SERS substrate. The characteristics of the sensor with two membrane structures were also studied and different filtering properties were obtained.. |

Odor Space Visualization with Molecular Recognizing Optical Chemical Sensor
The odor space visualization is realized by an odor image sensing technique, the sensor was developed by using an odor imaging film composed of fluorescence probes or a localized plasmon resonance (LSPR) plasmonic gas sensor. The developed odor image sensor can detect and visualize the shape, spread and concentration distribution of odor substances brought about by real odor sources such as body odor and gas leakage. Odor space information can be analyzed and decomposed to elemental odor profiles and spread/shape of each profile represent shape of remained odor substances. Such odor space information can be recognized easily by human.. |

Synthesis of odor based on substructures and physicochemical properties of odorants
In various fields related to odor, many trials have been done to quantify the quality of odor, however satisfying results have not been obtained yet. In this study, we made researches on synthesis of odor to develop the method that qualify odor properties. We chose the target odor substances and the elemental odor substances paying attention to substructure and physicochemical properties of odorants, and paying no attention to flavor of the odorants. The selected odorants were measured by means of a odor sensor using surface polarity controlling method, and mixed odors synthesized through analysis of sensor responses were evaluated by the sensor and human panels. As a result, target odor became possible to evaluate quantitatively by mixing some elemental odors.. |

Development of nitro-compounds sampling system for SPR-based landmine detector
Recently, damage by anti-personnel landmine is regarded as serious problems all over the world. However, conventional landmine detectors have many problems in respect of efficiency or reliability. From this reason, novel landmine detectors are desired. In landmines, the nitro compounds such as trinitrotoluene (TNT) and dinitrotoluene (DNT) are contained, and those substances are leaking from the inside of a landmine into the air. Therefore landmine detection is possible by detecting such nitro compounds. In this report, we developed a sampling system used a preconcentrator as a part of development of a SPR landmine detection system. We experimented to improve the concentrating rate in this system. As a result, this preconcentrator concentrated about 140 ppb DNT vapor by 35 times at the maximum. This result indicates that the the sensor to detect very low-concentration nitro compounds is effective for landmine detection.. |

Development of nitro-compounds preconcentrator for biosensor to detect landmines
20,000 or more people have been injured and killed per a year by anti-personnel mines. However, detection of landmines using metal detectors has reached the limit on effciency and reliability. It is desired that landmine detectors have higher reliability and easy handling. The aromatic nitro compounds like trinitrotoluene are used as the main explosives of landmines, and hence it is possible to detect landmines by detection of TNT and its derivatives, such as dinitrotoluene(DNT). In this report, we developed the preconcentration system used preconcentrator as a part of development of a mine detection biosensor system. This preconcentrator could concentrate about 140 ppb DNT 35 times. This method enables us to develop the sensor system which can detect a very low-concentration aromatic nitro compounds with extremely low cocentrations.. |

Supersensitive Detection of Explosives with Molecular Recognition Nano-Ultrathin Membrane in Surface-Polarization Controlling Method
Thin oxide layers with nano-controlled structures are known to display advantages for designing unique chemical functions. In this study, we developed a Ti0_2 gel ultrathin film immobilized with γ-CD, which is one of the molecular recognition compounds, as a sensing device for detecting of explosives in electrochemical impedance spectroscopy (EIS),i.e., surface-polarization controlling method. The surface molecular imprinting using γ-CD onto the TiO_2 gel ultrathin film greatly enhanced the sensitivity and selectivity of the sensor for explosives, especially for 2,4-dinitrotoluene (DNT).. |

Detecting of aromatic nitro compounds with electrode polarization controlling sensor
While the international public opinion of abolition of landmines is increasing, development of landmine detection technology progresses slowly, so detection activities are mainly performed with metal detectors that are not only inefficient but also dangerous. Therefore, the more efficient landmine detection method is desired. Most landmines contain aromatic nitoro compounds like DNT or TNT as explosive charge, and it is possible to perform landmine detection by detection of these substances that exist near a landmine. In this report, we tried to detect aromatic nitro compounds by using electrode polarization controlling method. The results showed that we could sensitively detect about under ppm aromatic nitoro compounds. and this method enables us to develop the sensor for landmine detection.. |

Evaluation of partial structure of odorants using odor responses of surface polarity controlled sensor
In biological systems odorants are received by a large number of receptors. In the process of the reception, not whole structures but partial structures of molecules are recognized, and it is referred that the odor quality is recognized depending upon their combinations. In this research, paying attention to the process of human odor reception in which these receptors detect many odorant molecules with multi modal interactions, the development of a novel odor sensing system had been attempted. Utilizing surface polarity controlling method as a transducer of the sensor, many odorant molecules were detected through interaction on the surface of the electrode. Paying attention to alcohols, aromatic compounds and aromatic alcohols as odorants, the discrimination of their responses by similar molecular structures was attempted. As a result, output patterns of this sensor were reflected by partial structures of odorant molecules, and it became possible to evaluate odorants by them.. |

Detection of Aldehyde and Carboxylic Acid Using Surace-Polarity Contorolled Sensor
Aldehyde and carboxylic acid compounds are known as bad smell substances. It also said to cause bad smell of tap water. In this study, we tried detection and analysis of aldehyde and carboxylic acid dissolved in the water, using the surface-polarity controlled sencor. The sencor measuers electrochemical impedance of the electrode surface whose electric potential is dynamically controlled, and the impedance changes depending on the electrode potential are used as a chemical sensor output. As a result, we could detect and recognize many kinds of aldehyde and carboxylic acid. The results suggest the possibility of the simple sensor construction for environmental analysis.. |

The gas sensor using percolation of graphite dispersion
Even now human nose is indispensable for the quality control and product development in manufacture of food, cosmetics and perfume. However, human cannot bear a test for hours and the result is influenced by each health condition. And in environmental measurement or a safety control, we have to inspect such odors as a bad smell and a dangerous smell. Furthermore, results by human nose have deviations by individual differences. It is therefore necessary to develop a sensing device, which can evaluate a smell. In this research, we directed our attention to graphite dispersion as a new transducer for electro nose. As a result, we could make the gas sensor using percolation of graphite dispersion and measure the percolation character of this device. And then we could attain raising the sensitivity to the chloroform by using the percolation phenomenon.. |

High Sensitive Detection of Environmental Hormones with Electrode Polarity Controlling Method
It has been noticed recently that there is a possibility of elution of chemical substances from packages of foods. The chemicals act as harmful substances such as environmental hormones for biological bodies at very low concentration. It is therefore necessary to develop a sensing device, which can detect such substances easily and quickly. The purpose of the present study is high sensitive measurement of environmental hormones using electrode polarity controlling method. The responding ability of the polarity-controlled sensor covers various chemicals from electrolytes to nonelectrolytes and from hydrophilic to hydrophobic substances. As a result, we could sensitively detect environmental hormones in ppb order and could get the character of environmental hormones. The present sensor could distinguish such chemicals from ordinary taste sumstances. Furthermore, by improving the surface treatment of electrode, the neutral substance was detected specifically.. |

Ju M. J., Hayashi K., Toko K., Analysis of Taste of Amino Acids Using Surface Polarity Controlling Sensor (化学センサ・その他有機,生体材料一般 ショートプレゼンテーション(ポスターセッション)), 電子情報通信学会技術研究報告. OME, 有機エレクトロニクス, 2000.08, Taste of amino acids was studied using a method to detect the change of interaction between the electrode surface and the taste substances in the aqueous solution. Amino acids exhibit complex taste compositions, e.g., sweetness, bitterness, sourness and umami. The sensor impedance shows different pontential profile patterns for amino acids which have different taste qualities, while it shows similar patterns for the amino acids with similar tastes. Amino acids can be classified into four groups according to their own tastes with sensor outputs. It implies that the taste of amino acid can be measured with the present method and be explained from the interaction based on the electrode polarity. The sensor response has good correlation with human sensitivity and higher sensitivity than that of a human sensation. The present method can provide useful transducers in the development of a sensor which can analyze taste qualitatively and quantitatively.. |
