    • This invention relates to a surface coating for capture circulating rare cells, comprising a nonfouling composition to prevent the binding of non-specific cells and adsorption of serum components; a bioactive composition for binding the biological substance, such as circulating tumor cells; with or without a linker composition that binds the nonfouling and bioactive compositions. The invention also provide a surface coating for capture and purification of a biological substance, comprising a releasable composition to release the non-specific cells and other serum components; a bioactive composition for binding the biological substance, such as circulating tumor cells; with or without a linker composition that binds the releasable and bioactive compositions. The present invention also discloses a novel microfluidic chip, with specific patterned microstructures to create a flow disturbance and increase the capture rate of the biological substance.
    • 本发明涉及用于捕获循环稀有细胞的表面涂层,其包含防止非特异性细胞结合的非结垢组合物和血清成分的吸附; 用于结合生物物质的生物活性组合物,例如循环肿瘤细胞; 具有或不具有结合非结垢和生物活性组合物的接头组合物。 本发明还提供用于捕获和纯化生物物质的表面包衣,其包含可释放组合物以释放非特异性细胞和其它血清成分; 用于结合生物物质的生物活性组合物,例如循环肿瘤细胞; 具有或不具有结合可释放和生物活性组合物的接头组合物。 本发明还公开了一种具有特定图案化微结构的新型微流体芯片,以产生流动扰动并增加生物物质的捕获率。

    • A voice coil driving auto-focus lens module is disclosed. The voice coil driving auto-focus lens module includes a base, two conductive plates, an insulation spacer, four permanent magnets, a lens holder, an optical lens, a spring set, a coil, and a top cover. The lens holder, the optical lens and the coil form a lens set that moves synchronously while the permanent magnets are fixed on an outer circle of a leaf spring. The spring set includes a coil spring and a leaf spring. By resultant spring force due to extension or compression of the coil spring as well as the leaf spring, together with the electromagnetic force, the lens module moves fast, focuses stably and the tilt of the lens module is reduced.
    • 公开了一种音圈驱动自动对焦透镜模块。 音圈驱动自动对焦透镜模块包括基座,两个导电板,绝缘垫片,四个永磁体,透镜架,光学透镜,弹簧组件,线圈和顶盖。 透镜架,光学透镜和线圈形成同时移动的透镜组,同时将永磁体固定在板簧的外圆上。 弹簧组包括螺旋弹簧和板簧。 由于由于螺旋弹簧以及板簧的延伸或压缩而产生的弹簧力,与电磁力一起,透镜模块快速移动,稳定地聚焦,并且减少了透镜模块的倾斜。
