In a landmark case in early 2025, a team of physicians created a personalized, bespoke CRISPR treatment for an infant with a rare genetic disease, developing and delivering it in just six months2 . This breakthrough signals a new era where biology is becoming a programmable technology.
Imagine a world where doctors can edit your genes to cure inherited diseases, bacteria are engineered to eat plastic pollution, and artificial leaves convert sunlight into clean fuel. This is not science fictionâit is the reality being built today in biological engineering labs around the globe. Biological engineering stands at the intersection of biology, engineering, and computer science, treating biological systems as programmable platforms to solve some of humanity's most pressing challenges5 .

Engineering tissues and sustainable materials from biological components
The CRISPR-Cas9 system has evolved from a powerful gene-editing tool into a refined therapeutic platform1 . What makes today's gene editing revolutionary is the development of sophisticated delivery systems like lipid nanoparticles (LNPs)âtiny fat particles that safely carry editing components to target cells2 . Unlike viral delivery methods that can trigger immune reactions, LNPs enable something previously impossible: redosing patients to increase treatment effectiveness2 .
The applications are expanding from rare diseases to common conditions. In 2025, clinical trials are targeting heart diseaseâa leading cause of death worldwideâwith highly positive early results2 . Synthetic biology, which blends biology and engineering, is also revolutionizing how we produce everything from pharmaceuticals to biofuels by using cells as "factories"1 . This field is projected to grow tenfold, potentially reaching $100 billion by 20301 .

Artificial intelligence is accelerating biological discovery at an unprecedented pace. AI-driven platforms like DeepVariant can quickly and accurately identify genetic variations linked to diseases, enhancing both diagnostics and the development of targeted therapies1 .
Perhaps the most dramatic impact of AI is in drug discovery, where machine learning models can predict the effectiveness and safety of potential compounds through simulations, potentially reducing discovery timelines from years to months. Breakthroughs like DeepMind's AlphaFold are offering new ways to understand protein structures, allowing researchers to design innovative proteins for enzyme production and targeted drug delivery1 .
The field of regenerative medicine is making significant strides, with increased investment in cell therapies and tissue-engineered products1 . 3D bioprinting is evolving to create complex, functional tissues and even organs. Researchers are working on improving printing methods and developing bioinks that closely mimic natural tissues1 .
In 2025, progress in multi-material bioprinting is enabling hybrid tissues that combine synthetic and biological components, bringing us closer to artificial organs that function like the real thing1 . These advancements are particularly important for addressing the shortage of donor organs and developing new treatments for conditions like osteoarthritis, heart disease, and spinal cord injuries1 .
In a groundbreaking study from the Lawrence Berkeley National Laboratory, scientists have created an artificial leaf that mimics photosynthesis to convert carbon dioxide into valuable chemicals7 . This work, part of the Liquid Sunlight Alliance (LiSA) project, represents over twenty years of research culminating in a device that brings us closer to replicating the productivity of a natural leaf.
"Their goal was ambitious: to create a self-contained system that could use sunlight to convert COâ into C2 productsâprecursor chemicals for countless everyday products, from plastic polymers to jet fuel"7 .
The research team followed nature's blueprint while innovating with advanced materials:
The team used lead halide perovskite to imitate a leaf's light-absorbing chlorophyll. This material, commonly used in advanced solar panels, efficiently captures solar energy7 .
Inspired by enzymes that regulate photosynthesis in nature, the researchers designed electrocatalysts made of copper that resemble tiny flowers. While biological alternatives offer higher selectivity, copper provides greater durability and stability7 .
Using instruments at Berkeley Lab's Molecular Foundry, the team integrated the device with metal contacts, creating a complete artificial-leaf architecture about the size of a postage stamp7 .
The device was placed under a solar simulator that mimicked consistently bright sunlight to test its efficiency in converting COâ into valuable C2 molecules7 .
The artificial leaf successfully demonstrated the conversion of COâ into C2 chemicals using only sunlight7 . This breakthrough is significant for several reasons:
First, it provides a proof of concept for sustainable chemical production. Rather than relying on fossil fuels, this approach uses sunlight and carbon dioxideâtwo abundant resourcesâas feedstocks. Second, the use of inorganic materials like copper makes the system more durable and longer-lasting than previous attempts that incorporated biological components7 .
Most importantly, this research opens a pathway to carbon-neutral manufacturing. The C2 chemicals produced are precursor ingredients for many industries, including plastics and aviation fuelsâparticularly valuable for larger vehicles that cannot yet run on batteries7 .

The implications of biological engineering extend far beyond laboratory walls, impacting multiple sectors of society and industry.
Researchers are developing Data-Driven Synthetic Microbes (DDSM)âengineered microorganisms designed through integrating omics, machine learning, and systems biology to tackle challenges like PFAS degradation and greenhouse gas mitigation8 . Microbial communities are being engineered to break down pollutants, including oil spills and plastics, accelerating the transition toward environmentally sustainable practices1 8 .
In medicine, biological engineering is enabling revolutionary approaches. Microrobotics is transforming drug delivery, with research groups developing microrobots capable of delivering drugs directly to targeted areas, such as tumor sites, with remarkable accuracy. These robots are designed to navigate the body's complex systems, offering unprecedented potential for treating conditions like cancer and cardiovascular diseases while minimizing side effects.
Despite rapid progress, biological engineering faces significant challenges. Deliveryâgetting therapeutic components to the right cellsâremains one of the biggest hurdles in CRISPR medicine2 . Environmental and safety concerns about bioengineered organisms potentially disrupting ecosystems require careful management5 . Ethical considerations around gene editing and equitable access to these advanced therapies continue to spark important societal debates1 5 .
Funding pressures also present challenges, with venture capital investment in biotechnology fluctuating based on market forces2 . Additionally, governments are still working to grasp the scale of the bio-opportunity, and strategic investment in foundational research remains crucial5 .
We are entering what many experts call the "biological century," where biotechnology is poised to emerge as a general-purpose technology that could become the foundation of a more resilient manufacturing base5 .
The convergence of biology with engineering and computer science is creating unprecedented opportunities to address global challenges in health, sustainability, and manufacturing.
As Drew Endy of Stanford University notes, biotechnology is already 5% of U.S. GDP and poised for significant growth5 . The future of biological engineering promises not just incremental improvements but fundamental transformations in how we live, heal, and interact with our planet. From personalized CRISPR treatments to artificial leaves that clean our atmosphere, the bio-revolution is just beginningâand its potential is limited only by our imagination and our commitment to responsible innovation.
