Cell-Free Systems Accelerate Protein Engineering and Biosensor Development
Scientists are increasingly bypassing living cells to synthesize proteins and create biosensors using cell-free transcription and translation systems. By extracting cellular machinery from organisms like E. coli or plants, researchers can accelerate the design-build-test cycle from weeks to hours, enabling the production of toxic compounds and the rapid iteration of sensors for contaminants like lead and copper. While these systems offer high customizability and avoid the risks of releasing genetically modified organisms, they face significant challenges regarding cost, energy depletion, and scalability compared to traditional cell-based methods.
