This paper develops a distributed feedback control system in microbial consortia to precisely regulate gene expression across different cell populations.

Cheetah is a computational toolkit that integrates real-time microscopy analysis with cellular control algorithms, demonstrating improved segmentation accuracy over thresholding methods in bacterial and mammalian cells.

ChipSeg segments bacterial and mammalian cells in microfluidic devices using thresholding, enabling fluorescence quantification and cell tracking in time-lapse experiments.

The paper demonstrates real-time feedback control of a molecular titration motif in E. coli using microfluidics and validates the approach with in silico simulations.

The paper describes a low-cost, open-source turbidostat for in-vivo control experiments in synthetic biology and reports results from a 3-hour optical density control experiment.
