Biosensor chip for SPR (Surface Plasmon Resonance) detection

The utility model relates to the technical field of biological inspection and detection, and particularly discloses a biological sensing chip for SPR (Surface Plasmon Resonance) detection, which comprises a metal film for bearing a substance to be detected, a light-transmitting medium-metal film interface for SPR detection is established between the metal film and a light-transmitting medium, the metal film is a metal film in an electrode array form, and the light-transmitting medium-metal film interface is a transparent medium-metal film interface. And the electrode array is connected to an alternating current signal source. The biosensor chip solves the technical problem that the result is inaccurate due to overlong biological binding reaction time in traditional SPR detection. 本实用新型涉及生物检验检测技术领域，具体公开了一种用于SPR检测的生物传感芯片，包括，用于承载待测物质的金属膜，该金属膜与透光介质建立有一用于SPR检测的透光介质-金属膜界面，该金属膜为电极阵列形式的金属膜，所述电极阵列连接至一交流信号源。该生物传感芯片解决了传统SPR检测中生物结合反应时间过长，使结果不准确的技术问题。
