Area of Science:

• Biomaterials Science
• Microfluidics
• Network Synthesis

Background:

• Ordered microgel networks are crucial for applications in tissue engineering, regenerative medicine, drug delivery, optics, and electronics.
• Existing methods for synthesizing these networks can be costly and lack precise control.

Purpose of the Study:

• To demonstrate tailorable and reproducible microgel synthesis and patterning using a microfluidics tubing system.

Main Methods:

• Microfluidic formulation and incubation of gel precursor microdroplets.
• Spatiotemporal control of microgel patterning and integration via a tubing system.
• Network formation through interface crosslinking or lipid bilayer formation.

Main Results:

• Successful synthesis of ordered networks from both heterogeneous (multi-phase) and homogeneous microgels.
• Precise control over microgel sequencing and assembly at the tubing outlet or within enlarging tubing.
• Demonstration of tailorable and reproducible microgel properties.

Conclusions:

• The developed microfluidic synthesizer offers an efficient and cost-effective approach for creating ordered microgel networks.
• This technology holds significant potential for advancing applications in various fields, including tissue engineering and controlled delivery.
