    Area of Science:

    • Microfluidics
    • Materials Science
    • Biotechnology

    Background:

    • Portable microfluidic devices require efficient, user-friendly pumping mechanisms.
    • Existing pumps often have limited capacity or material compatibility.

    Purpose of the Study:

    • To develop a power-free, modular pump for portable microfluidic applications.
    • To investigate the influence of pump module geometry on pumping performance.

    Main Methods:

    • A degassed polydimethylsiloxane (PDMS) slab with an integrated mesh-shaped chamber was designed as a pump module.
    • The pump module was attached to microfluidic device outlets to create negative pressure.
    • The effect of pump geometry (surface area, exposure area, volume) on pumping capacity was analyzed.

    Main Results:

    • The modular pump is power-free, easy to use, and compatible with various microfluidic device materials.
    • Pumping performance is significantly influenced by the pump chamber's surface area, PDMS slab exposure area, and volume.
    • Initial air volume and PDMS cross-linking degree also impact pump efficiency.

    Conclusions:

    • The developed modular pump offers a versatile and adaptable solution for portable microfluidics.
    • The study provides insights into optimizing pump module design for desired pumping performance.
    • The pump's utility was demonstrated in both glass-based and PDMS-based microfluidic systems.
