Area of Science:

  • Biomedical Engineering
  • Microfluidics
  • Cell Biology

Background:

  • Cell culture requires precise control over the microenvironment.
  • Traditional methods often need complex equipment and external pressure sources.
  • Developing simpler, self-regulating systems is crucial for broader accessibility.

Purpose of the Study:

  • To develop a disposable passive microfluidic device for cell culturing.
  • To enable controlled media and drug flow without external pressure sources.
  • To demonstrate the device's capability for culturing various cell lines.

Main Methods:

  • Fabrication of a two-layer Polymethylmethacrylate (PMMA) device using micro-milling and solvent-assisted bonding.
  • Utilizing regulated fluidic column heights and well apertures for passive flow control.
  • Characterizing flow rates and diffusion using simulations and experimental methods.
  • Performing cell culturing experiments with melanoma, HeLa, Jurkat, A549, and HEK293T cell lines.

Main Results:

  • Achieved a stable flow rate of 18.6 μl/h with a 7% daily decrease due to fluid height reduction.
  • Successfully cultured melanoma tumor cells for 48 hours.
  • Demonstrated successful cultivation of HeLa, Jurkat, A549, and HEK293T cell lines for 72 hours.

Conclusions:

  • The passive microfluidic device offers a simple, disposable, and effective platform for cell culture.
  • The device allows for controlled temporal changes in media and drug delivery.
  • It provides a viable method for long-term culture of diverse cell lines without external pressure systems.
