This article utilizes hollow glass capillaries to achieve siphon valve effects by embedding specifically shaped hollow glass capillaries at the siphon valve location. By leveraging the inherent hydrophilicity of the inner walls of the hollow glass capillaries, local hydrophilicity is achieved without altering the overall surface characteristics of the chip, thus facilitating siphon drainage.Figure 1 … Read more
