Synthetic biology

Definition

Synthetic biology is an interdisciplinary field that combines biology, engineering, and computer science to design and construct new biological parts, devices, and systems. This approach allows scientists to modify existing organisms or create new ones with specific functions, thereby enabling innovative applications in areas such as medicine, agriculture, and environmental sustainability. By harnessing the principles of engineering, synthetic biology aims to make biological systems more predictable and efficient.
