Summary
We developed a system to control microscopic organisms using light stimuli. This programmable microfluidic device enables interactive control of cell swarms for various applications.
Area of Science:
- Microfluidics
- Biotechnology
- Collective behavior
Background:
- Microscopic agents like Euglena gracilis exhibit phototaxis.
- Controlling swarms of microorganisms in microfluidic devices is challenging.
Purpose of the Study:
- To present a hardware setup and programming language for spatiotemporal control of micro-organism swarms.
- To demonstrate the utility of this system through a biotic game.
Main Methods:
- Utilized spatiotemporal light stimuli to direct Euglena gracilis motion.
- Developed three programming abstractions: stimulus space, swarm space, and system space.
- Created a scripting language for swarm manipulation within a microfluidic chip.
Main Results:
- Successfully demonstrated interactive control of a micro-organism swarm.
- Implemented a multi-level proof-of-concept biotic game.
- Established executable commands for precise swarm manipulation.
Conclusions:
- The developed device and programming concepts offer enhanced capabilities for manipulating natural and synthetic swarms.
- Future applications include on-chip processing, diagnostics, education, and research on collective behaviors.
