    • A light-assisted biochemical sensor based on a light addressable potentiometric sensor is disclosed. The light-assisted biochemical sensor comprises a semiconductor substrate and a sensing layer, which are used to detect the specific ion concentration or the biological substance concentration of a detected solution. Lighting elements fabricated directly on the back surface of the semiconductor substrate directly illuminate the light to the semiconductor substrate, so as to enhance the photoconduction property of the semiconductor substrate. And then, the hysteresis and the sensing sensitivity of the light-assisted biochemical sensor are respectively reduced and improved. In addition, due to its characteristics of integration, the light-assisted biochemical sensor not only reduces the fabrication cost but also has portable properties and real-time detectable properties. As a result, its detection range and the application range are wider.
    • 公开了一种基于光寻址电位传感器的光辅助生化传感器。 光辅助生化传感器包括半导体衬底和感测层,用于检测检测到的溶液的特定离子浓度或生物物质浓度。 直接在半导体衬底的背面上制造的照明元件直接将光照射到半导体衬底上,以提高半导体衬底的光电导性。 然后,分别降低和改善了光辅助生化传感器的滞后和感测灵敏度。 另外,由于其综合特性,光辅助生物传感器不仅降低了制造成本,而且具有便携性和实时可检测性。 因此,其检测范围和应用范围更广。
