The future of science lies not just in discovering nature's secrets, but in learning to rewrite its code.
Imagine a future where doctors treat cancer by reprogramming your own cells, where factories grow sustainable materials from living microbes, and where endangered species can be engineered to resist fatal diseases. This is not science fiction—it is the promising reality being built today in the labs of synthetic biologists and polymer scientists. These fields, though distinct, are converging to create a new era of biological engineering, and they are now in the scientific spotlight with the launch of two new dedicated ACS Web journals.

Synthetic biology is a multidisciplinary field that applies engineering principles to living systems. It involves designing and constructing new biological parts, devices, and systems, or redesigning existing ones found in nature for useful purposes7 . In essence, it treats biology as a technology, allowing scientists to program organisms much like we program computers.
The goal is to produce predictable and robust systems with novel functionalities that do not already exist in nature7 . This could mean engineering bacteria to produce life-saving drugs, creating living cells that can diagnose and treat disease from within the body, or even designing entirely synthetic genomes4 .
The synthetic biology market is projected to grow from about $10 billion in 2021 to between $37 billion and $100 billion by 20304 . This explosive growth is fueled by groundbreaking achievements in genetic engineering and cellular programming.
While synthetic biology rewrites the instructions, polymer science provides the very material of life. A polymer is a large molecule made up of many smaller, repeating units called monomers, linked together like a chain5 .
Think of it like a box of building blocks. Individually, each block is simple. But when you connect them in long chains, you can create structures with unique properties—some soft and flexible, others hard and strong5 .
The famous double helix is a complex polymer that stores genetic information.
The workhorses of the cell, from muscle tissue to enzymes.
The structural material of plant cell walls is a polymer of glucose.
You can witness the creation of a polymer right in your own kitchen5 .
The science: Milk contains casein protein that polymerizes when acid is added.
Engineered immune cells to target cancer; next-generation vaccines; "living therapeutics"4 .
Development Progress: 85%Modified bacteria to create eco-friendly fertilizers; organisms that consume CO₂ or turn methane into biodegradable plastics4 .
Development Progress: 65%Sustainable fabrics (e.g., spider silk from silkworms); biofuels; commercially available cheese and cell-cultured meats4 .
Development Progress: 75%Engineering nutrients for crops into bacteria and engineering plant resilience.
Development Progress: 70%| Tool or Reagent | Function | Example Use Case |
|---|---|---|
| DNA Synthesis | Chemically producing DNA molecules from scratch7 . | Creating a completely synthetic bacterial genome4 . |

AI-designed programmable synthetic organisms blurred lines between traditional organisms and machines.
"Living therapeutics" reported4
Engineered human or microbial cells treat diseases directly in patients.
The technology can be applied to diagnose and treat diseases, improve industrial processes, and address environmental challenges.
Many of the core tools are becoming low-cost and widely available, which could democratize biotechnology innovation.
Offers new tools to help protect biodiversity, such as making endangered plants more resilient to pests.
The technology could be misused to create new biological weapons, and computational tools are vulnerable to cyber threats.
Releasing synthetic organisms could have unintended and potentially irreversible effects on ecosystems.
Interfering with the "code of life" raises ethical questions, and the public may hesitate to accept certain applications.
The launch of dedicated ACS Web journals for synthetic biology and polymer science is a testament to their maturity and explosive growth. They are no longer niche specialties but central pillars of 21st-century innovation. By providing a dedicated platform for research, these journals will accelerate the dialogue between scientists, help establish standards, and showcase how these fields are working in concert to build a healthier, more sustainable, and technologically advanced future. The journey to engineer life is just beginning, and its progress will be chronicled in the pages of these new publications.
