Monolithically 3D-Printed Microfluidics with Embedded µTesla Pump

Area of Science:

• Biomedical Engineering
• Microfluidics
• 3D Printing

Background:

• Microfluidic devices offer transformative potential but often suffer from disconnected components and reliance on time-consuming manual fabrication.
• Existing integration methods can lead to device variations and limit scalability.

Purpose of the Study:

• To develop a framework for integrated microfluidics using 3D printing and novel pumping mechanics.
• To demonstrate wirelessly controlled microfluidic systems with improved performance and reduced shear stress for cell culture.

Main Methods:

• Characterization of 3D printed microfluidics with a minimum feature size of 100 µm.
• Integration of a microtesla (µTesla) pump for non-pulsatile flow.
• Incorporation of a radio frequency (RF) device and brushless motor for wireless remote control.

Main Results:

• Demonstrated the simplicity and performance of 3D printed microfluidic components.
• Achieved non-pulsatile flow with reduced shear stress on beta cells using the integrated µTesla pump.
• Successfully created a self-enclosed, wirelessly controlled microfluidic platform.

Conclusions:

• New physics and 3D printing approaches enable enhanced integration of microfluidic components.
• The developed platform facilitates novel cell-based studies and advances microfluidic research.
• This framework addresses the disconnect in microfluidic device development, paving the way for more sophisticated applications.
