摘要： A liquid storage and controlled-release device and a biological detection chip. The liquid storage and controlled-release device comprises a liquid storage capsule with a liquid storage body which is deformable under a pressure, and a sealing layer for sealing the liquid storage body. A support platform is provided right below the liquid storage capsule and tightly connected with the liquid storage capsule, wherein, a directional release chamber is provided at the middle of the support platform, and the directional release chamber is provided with a guiding chamber for collecting the liquid and a sharp edge for inducing break. Compared with the conventional technology, the opening for liquid release is at the end far away from the rotation center, so that the liquid can be released completely by the centrifugal force, ensuring the quantitative release of stored liquid and reducing the influence on the accuracy of the subsequent detection.
