Abstract:
PURPOSE: A peptide sensor for selective detection of explosive and a detection device are provided to ensure high selectivity to TNT or DNT. CONSTITUTION: A TNT-specific peptide has an amino acid sequence of sequence number 1, 2, 3, or 4. The peptide additionally contains a linker at carboxy terminal. A DNT-specific peptide has an amino acid sequence of sequence number 9, 10, or 11. The DNT-specific peptide additionally contains a linker at carboxy terminal. The linker is Gly-Cys. An explosive sensor contains the TNT or DNT specific peptide. A method for detecting TNT-specific peptide comprises a step of using 3-(2,4,6-trinitrophenoxy)propane-1-amino groups.

본 발명은 다채널 수정 결정 미소 저울에 관한 것으로서, 수정 결정의 공진 특성을 이용하여 미소 질량을 측정할 수 있는 수정 결정 미소 저울에 있어서, 상기 수정 결정으로 이루어진 수정 기판; 상기 수정 기판의 앞면에 배치된 제1 전극과, 상기 수정 기판의 뒷면에 상기 제1 전극과 대향하도록 배치된 제2 전극이 쌍을 이루는 복수 쌍의 전극;을 구비하며, 상기 수정 기판은, 상기 수정 기판의 표면에 오목하게 형성된 구획홈에 의하여 복수 개의 센싱 영역으로 분리되며, 상기 각 쌍의 전극은, 상기 구획홈에 의하여 분리된 복수 개의 센싱 영역에 각각 배치되어 있는 것을 특징으로 한다. 본 발명에 따르면, 수정 기판의 표면에 오목하게 형성된 구획홈에 의하여 각 쌍의 전극이 서로 분리된 상태로 배치됨으로써, 각 전극에서 발생하는 진동이 주변의 다른 전극에 미치는 간섭을 감소시킬 수 있는 효과가 있다.
Abstract:
PURPOSE: A sensor using a metal oxide nanotube and a manufacturing method of the same are provided to facilitate to change the structure of a nanotube and to adjust the wall thickness of the nanotubes by an atomic layer unit by manufacturing the nanotube through an atomic deposition layer. CONSTITUTION: A manufacturing method for a sensor using metal oxide nanotube(110) comprises the following steps: forming an aluminum oxide nanotube mold; forming a metal oxide thin film on the mold surface of aluminum oxide nanotube with an atomic layer deposition; forming the dual-structured nanotube of an aluminum oxide mold and a metal oxide thin film; depositing a first electrode(130) to the first tip end of the dual-structured nanotube of an aluminum oxide mold and a metal oxide thin film; partially exposing the metal oxide thin film by partially removing the aluminum oxide nanotube mold in the second tip end of the dual-structured nanotube of an aluminum oxide mold and a metal oxide thin film; depositing a second electrode(120) to the second tip end to which metal oxide thin film is partially exposed; and forming a metal oxide nanotube which is equipped with the first and second tip ends by removing the remained aluminum oxide nanotube mold.
Abstract:
PURPOSE: A flow sensor and a flowmeter using the same are provided to utilize a RTD(RTD) sensing unit and a temperature sensing unit by variably controlling the same, thereby being flexible in responding to a flow rate, a speed, and a sort of fluid. CONSTITUTION: A flow sensor(100) comprises a rectangular substrate(10), three or more heat generation patterns(20), an electric circuit pattern(30), and an electrode pad(40). The heat generation patterns are parallelly formed in one side end portion of a longitudinal direction of the substrate along a width direction. The electric circuit pattern is formed by being extended from each end of the heat generation patterns to the other side end portion of the substrate. The electrode pad is formed on the substrate to be connected to the other side end portion of the electric circuit pattern which is not connected to the electric circuit patterns. The heat generation pattern arranged in both edge portions among the heat generation patterns is a RTD sensor and the heat radiation pattern in an inner side of the RTD sensor is a heater.
