Synthetic biology is an interdisciplinary field that seeks to design and construct new biological parts, devices, and systems, or to redesign existing biological pathways for useful purposes. Building on molecular biology and genetic engineering, it combines biology with engineering, computer science, and chemistry to apply standardized parts, modular design, and quantitative modeling to living systems.

Key approaches include creating standardized DNA parts and genetic circuits, synthesizing DNA and genomes, editing genes with technologies such as CRISPR, and using cell-free systems and chassis organisms to prototype functions quickly. Computational tools, automation, and high-throughput screening support design-build-test cycles aimed at predictability and scalability.

Applications span medicine (therapies, vaccines, diagnostics), industrial biotechnology (production of fuels, chemicals, and materials), agriculture (engineered crops and pest resistance), and environmental uses (bioremediation and biosensing). Synthetic biology also contributes to research tools, such as programmable biosensors and standardized plasmids.

The field emerged from genetic engineering in the late 20th century and matured in the 2000s with the development of DNA synthesis, standardization efforts, and genome-scale projects. Milestones include synthetic genomes and minimal cells, while ongoing work focuses on safety, reproducibility, and responsible deployment.

Biosafety and biosecurity considerations shape governance: risk assessment, regulatory oversight of DNA synthesis, and ethical discussions about dual-use potential, environmental impact, and access. The community emphasizes responsible innovation, transparent reporting, and international collaboration to balance benefits with safeguards.
