Abstract: 본 발명은 나노갭의 이격거리를 갖는 전극 쌍을 이용하여 나노입자의 유무, 농도, 입도 분포 및 종류를 검출하는 나노입자 검출센서에 관한 것으로, 상세하게는 나노 갭을 갖도록 이격되어 형성된 한 쌍의 전극을 단위 전극으로 하여, 전기적으로 서로 독립되게 작동하는 다수개의 상기 단위 전극으로 구성된 단위 유닛을 포함하며, 상기 나노 갭에 포착된 나노입자에 의해 전기적 변화된 상기 단위 전극의 수를 기반으로 나노입자를 검출하는 특징이 있다.
본 발명의 나노입자 검출센서는 단일한 측정에 의해 나노입자의 물질 종류, 나노입자의 크기, 입도 분포 및 농도에 대한 검출이 가능한 장점이 있으며, 나노 갭을 갖는 다수의 전극쌍을 통한 통계적 검출에 의해 검출 시간을 단축시키면서 신뢰성 및 재현성이 높으며, 매우 낮은 농도의 나노입자 또한 검출 가능한 장점이 있다.

Abstract: A nano particle detector sensor using a nanogap electrode is provided to increase the reliability and reproducibility but reduce the detection time. A nano particle detector sensor using a nanogap electrode comprises a pair of electrodes(101,102) separated each other to have a nanogap with a unit electrode(110). The nano particle is detected by the nano particle caught by the nanogap. The nano particle detector sensor has a unit consisting of a plurality of unit electrodes electrically operating independently. The nano particle is analyzed from the number of the electrically changed unit electrode by the nano particle caught by the nanogap. The size of the nanogap is controlled in order to analyze the size of the nano particle.
