摘要： PURPOSE:To provide an odor sensor which can be used without a complicate measuring system and is more superior in stability of sensing properties than a prior art. CONSTITUTION:A comb-like electrode 13 of a gold thick film is formed on an alumina ceramics substrate 11. An application liquid is prepared by dissolving, e.g. 1g dioctylphosphate as a sensing agent, 10g vinyl chloride as a supporting polymer, 20g dioctylphthalate as a plasticizer in 100g tetrahydrofuran as a solvent. The substrate 11 with the electrode 13 is dipped in the application liquid. The application liquid is dried after the substrate 11 is pulled out to obtain a sensitive film. The electrode may be built in the sensitive film without using a substrate. The sensitive film may be a laminate of a plurality of individual sensitive films of different sensitivities. If the sensitive film is a laminate- type, an upper and a lower electrodes may be formed on the upper and lower surfaces of the film. Moreover, an intermediate electrode may be provided between the sensitive films of the laminate.

摘要： PURPOSE:To finely form a wiring on an LB film under ordinary temperature or under ordinary temperature with ordinary pressure by imparting a functional group to become a biotin mark to the surface of the LB film, and forming a biotin pattern on the surface, followed by being combined with avidin. CONSTITUTION:When a wiring is formed on an LB film 2, a functional group to become a mark of biotin 4 is imparted to the surface of the film 2 so as to form a biotin pattern to be combined with the surface of the film 2 through the functional group. Next, avidin 5 having metal colloid is combined with this biotin pattern by using specific combination of avidin 5 with biotin 4 so as to obtain the wiring. In this case, the functional group to become the mark of this biotin 4 is determined to be an amino group or a carboxyl group. Then, since a series of treatments can be under ordinary conducted under ordinary temperature, a desired wiring can be formed while allowing to be also formed cold. Further, since biotin pattern formation can be performed by a present fine pattern making technique such as electron ray exposure, untraviolet ray exposure and X-ray exposure, a desired fine pattern can be obtained.

摘要： PURPOSE:To detect a food-poisoning bacteria in a food constituent simply and quickly by bringing the food constituent into contact with a surface acoustic wave element on which an anti-food-poisoning bacteria antibody is stuck and by measuring a change in a frequency before and after the contact. CONSTITUTION:A surface acoustic wave oscillator 17 having transducers 13 and 15 provided on a crystal plate 11 of ST cut is covered with polystyrene and an anti-food-poisoning-bacteria antibody 19 is stuck between the two transducers 13 and 15, whereby a sensor 21 is prepared. This sensor 21 is connected with amplifiers 23 and 25 and a frequency counter provided between them. A food constituent is brought into contact with the sensor 21, and based on a change in a frequency before and after the contact, a food-poisoning bacteria in the food constituent is detected. The sensor 21 is subjected to washing in three times by a phosphoric acid buffer and protection of a nonspecific adsorption site by calf serum albumin, so as to prevent fluctuation in the frequency due to a cause other than combination of the food-poisoning bacteria.

摘要： PURPOSE:To obtain organic non-linear optical thin film element whose non-linear optical effect is large by constituting the material for the element of a specific p-alkyl aminobenzonitrile. CONSTITUTION:Since organic non-linear optical material is constituted of p-alkyl aminobenzonitrile shown by the equation I, it shows a non-linear optical effect without inversion symmetric property in a crystal state. If possible, the organic non-linear optical material is constituted of a thin film including p-alkyl aminobenzonitrle comprising long chains introduced in p-aminobenzonitrile whose molecule non-linear polarization rate is large and whose molecule arrangement orientation is controlled. By this, such a non-linear optical effect by which light corresponding to the second harmonics of incident light is generated can be obtained.
