From Silicon to Cells: Full-Adder Circuits in Biological Computing

Drew Endy founded synthetic biology promoting standardization and engineering principles. Tom Knight developed BioBricks—standardized genetic parts. iGEM (International Genetically Engineered Machine) competition engages thousands of students building synthetic circuits. Companies like Ginkgo Bioworks engineer organisms for industrial applications. Researchers publish circuit designs in registries enabling community reuse.

Chris Voigt and colleagues engineered genetic circuits performing arithmetic operations in bacteria. Synthetic biology teams construct increasingly complex computational circuits in cells. Researchers demonstrate binary addition, subtraction, and other arithmetic operations through gene regulation. Bioengineers envision cells as programmable computers executing custom genetic programs.

Michael Elowitz and Stanislas Leibler created the first synthetic genetic toggle switch and oscillator in 2000. Timothy Gardner constructed genetic logic gates. Chris Voigt engineered complex genetic circuits implementing Boolean logic. Synthetic biologists design programmable cells responding to environmental signals through genetic computation.

Mark Ptashne elucidated transcription factor mechanisms through lambda phage studies. Frances Arnold pioneered directed evolution of regulatory proteins. Synthetic biologists engineer transcription factor circuits implementing complex logic. Systems biologists model regulatory network dynamics predicting circuit behaviors.
