Synthetic biology represents an interdisciplinary field that applies engineering principles to biology, designing and constructing new biological parts, devices, and systems or redesigning existing natural biological systems for useful purposes. This sophisticated approach combines molecular biology, genetics, biochemistry, systems biology, and computational modeling with engineering concepts of standardization, modularity, and rational design to program living organisms with novel functions beyond their natural capabilities.
Unlike traditional genetic engineering making limited modifications to existing organisms, synthetic biology seeks to fundamentally redesign biological systems from first principles—creating standardized genetic parts that can be assembled into devices and systems with predictable behaviors. This engineering-driven paradigm enables the construction of living factories, sensors, therapeutic agents, and materials with precisely controlled functions, potentially addressing challenges in medicine, manufacturing, agriculture, energy, and environmental remediation through programmable biological solutions.
