BMJ open·2023

We created a plug-and-play microfluidic device simplifying chip-to-world connections. This innovative system uses integrated silicon micropumps for precise fluid control in chemical and biochemical analyses.

Area of Science:

Microfluidics
Biochemical analysis
Lab-on-a-chip technology

Background:

The chip-to-world interface presents a significant challenge in microfluidics.
Existing microfluidic systems often require complex external connections and setups.

Purpose of the Study:

To develop a user-friendly, "plug and play" microfluidic device.
To overcome the limitations of traditional chip-to-world interfaces in microfluidic applications.

Main Methods:

Development of a microfluidic device integrating a fluid driving unit and a polymer chip.
Incorporation of silicon-based micropumps for fluidic control.
Minimal external connections via electric control lines for the driving unit.

Main Results:
