Bacterial Biosensor Circuit Diagram - Synthetic Biology Sensor Design #1906244 (License: Personal Use)

This diagram illustrates a genetically engineered bacterial cell functioning as a multi-analyte biosensor. Inputs include trimethylamine N-oxide (TMAO), cobalt ions, cyclic GMP (cGMP), and brain natriuretic peptide (BNP), each activating specific promoters (torCAD, nha, PDES, constitutive) to express fluorescent proteins (RFP, YFP, CFP) or an enzyme (NPLA). The system integrates signal transduction pathways for real-time detection in diagnostics or environmental monitoring.

Used in synthetic biology educational resources, research publications, or biotech product documentation to explain modular biosensor design; targets researchers, students, and engineers seeking to understand or replicate multi-input genetic circuits.
