 Abstract engineered bacteria have great potential for medical and environmental applications. To realize this potential, it is necessary to develop methods for controlling and scaling up the behavior of engineered bacteria. A new platform technology, microbial swarm bot, has been developed to achieve this goal. This system uses spatial arrangement to control the growth dynamics of engineered bacteria, allowing them to survive only under certain conditions. Additionally, the system can detect changes in its environment and adjust its behavior accordingly. This modular approach allows for the development of integrated and programmable control of hybrid biological material systems for diverse applications.
