    • 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和血清组分吸附的防污组合物; 用于结合生物物质的生物活性组合物,如循环肿瘤细胞; 具有或不具有结合非污染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涂层,其包含释放非特异性细胞和其他血清组分的可释放组合物; 用于结合生物物质的生物活性组合物,如循环肿瘤细胞; 具有或不具有结合可释放组合物和生物活性组合物的接头组合物。 本发明还公开了一种新颖的微流控芯片,其具有特定的图案化微结构以产生流动扰动并增加生物物质的捕获速率。
