The progress in development of synthetic gene circuits has been hindered by the limited repertoire of available transcription factors. Recently, it has been greatly expanded using the CRISPR/Cas9 system. However, this system is limited by its imperfect DNA sequence specificity, leading to potential crosstalk with host genome or circuit components.… (More)
We describe a conceptual design of a distributed classifier formed by a population of genetically engineered microbial cells. The central idea is to create a complex classifier from a population of weak or simple classifiers. We create a master population of cells with randomized synthetic biosensor circuits that have a broad range of sensitivities toward… (More)
CRISPR-Cas9 has recently emerged as a promising system for multiplexed genome editing as well as epigenome and transcriptome perturbation. Due to its specificity, ease of use and highly modular programmable nature, it has been widely adopted for a variety of applications such as genome editing, transcriptional inhibition and activation, genetic screening,… (More)
An efficient computational algorithm is developed to design microRNA-based synthetic cell classifiers and to optimize their performance.
