Publication number: 20240118205Abstract: The invention provides a bacterial cellulose-based biosensor, including bacterial cellulose (BC) and a cell presenting a cellulose-binding module CBM2a on the surface. The cell is attached to BC through CBM2a. The cell expresses CBM2a by using pETDuet-tac as a vector. The pETDuet-tac is obtained by replacing two T7 promoters on the vector pETDuet by tac promoters, that is, an upstream first tac promoter and a downstream second tac promoter. The pETDuet-tac includes a gene encoding a fluorescent protein downstream of the first tac promoter and a gene encoding CBM2a presented on the surface downstream of the second tac promoter. By the BC-based biosensor, efficient and specific immobilization of cells on the BC matrix is enabled, the biological activity of cells is maintained, the fluorescence signal output is enhanced, and sufficient pores are provided for the entry and exit of a detected substance, thereby significantly improving the detection sensitivity.Type: ApplicationFiled: December 1, 2023Publication date: April 11, 2024Inventors: Lingfeng LONG, Fubao Sun, Yun Hu, Le Xie

Patent number: 11454366Abstract: The present disclosure provides an automobile lamp lighting system, including a light source, a reflecting mirror, a light-shielding plate, and a lens. The lens includes a reflecting surface and a refracting surface opposite to the reflecting surface. When an external parallel light is incident into the lens, the external parallel light sequentially passes through the refracting surface for a first refraction, is reflected by the reflecting surface, passes through the refracting surface for a second refraction, exits the lens, and is converged to form a focal point. The reflecting mirror includes a near focal point and a far focal point, the light source is arranged at the near focal point, and the far focal point is located near the focal point of the lens. The light-shielding plate includes a light-shielding plate cut-off line located at the focal point of the lens.Type: GrantFiled: April 10, 2018Date of Patent: September 27, 2022Assignee: HASCO VISION TECHNOLOGY CO., LTD.Inventors: Jie Zhang, Shikun Dong, Le Xie, Yang Liu
