Area of Science:

  • Biomaterials Science
  • Synthetic Biology
  • Microfluidics

Background:

  • Assembling stable, functional prototissues from protocell building blocks presents significant engineering challenges.
  • Existing methods lack precise control over prototissue size, composition, and collective behaviors.

Purpose of the Study:

  • To design and implement a microfluidic platform for the precise fabrication of bespoke prototissues.
  • To demonstrate control over prototissue composition and collective behaviors.

Main Methods:

  • Utilized a microfluidic platform for controlled assembly of two types of protein-polymer protocells.
  • Engineered prototissues with controlled size, composition, and Janus configurations.
  • Modulated collective behaviors by varying protocell number and type.

Main Results:

  • Achieved precise control over prototissue size, composition, and Janus configurations.
  • Demonstrated modulation of thermally induced contraction amplitude.
  • Showcased control over collective endogenous biochemical reactivity.

Conclusions:

  • Microfluidic technologies offer a novel, high-throughput method for fabricating tissue-like materials with programmable properties.
  • Precise assembly of diverse protocell building blocks enables tunable collective behaviors.
  • Bespoke prototissues are foundational for developing advanced artificial tissues in medicine and robotics.
