Imagine a material so porous that a spoonful hides the surface of a football field – and that surface quietly pulls drinking water from desert air or carbon dioxide from smokestacks. That is the Groundbreaking Invention Nobel Laureate Omar Yaghi is now pushing from lab benches to real life.
This new generation of crystalline “super-sponges” is not just a chemistry curiosity. It is pitched as a toolbox for cities under water stress, industries under climate pressure and households seeking cleaner air. The promise feels almost science‑fiction, yet it already has a Nobel Prize in its corner.
How Omar Yaghi’s radical materials rewrote modern chemistry
In the 1990s, at the University of Michigan and later UCLA, Yaghi began asking a question many colleagues judged unrealistic: could matter be built like Lego, one molecule at a time, with long‑range order instead of random clumps? That question gave birth to reticular chemistry, the discipline behind his Scientific Discovery.

The payoff came in 1999 with MOF‑5, a zinc-based metal-organic framework whose internal surface area stunned the community. A few grams of this powder hosted as much inner surface as a football pitch. That level of porosity turned an abstract idea into a platform Technology and later helped earn Yaghi the 2025 Nobel Prize in Chemistry, shared for “reimagining what solid matter can be”. Background details of his journey, from early UCLA years to global recognition, are recounted in reports such as this UCLA profile on his Nobel win.
The birth of MOFs, COFs and the “molecular Lego” age
Metal-organic frameworks (MOFs) and their all-organic cousins, covalent organic frameworks (COFs), look like crystals under a microscope. Inside, however, they resemble vast 3D scaffolds of cages and tunnels measured at the nanoscale. Each cage can host a molecule of water, carbon dioxide or a targeted chemical.
Yaghi’s insight was to treat these frameworks like programmable architecture. Choose a metal “node”, pick organic linkers as beams, decide pore size, then decorate the internal walls with functional groups that favour one molecule over another. The result is a library of materials that can be tuned almost like software – a concept that underpins his growing reputation as a visionary of matter design.
The mission: turning air into water and pollution into a resource
Behind the headlines about a Global Impact lies a clear objective: translate molecular precision into devices that tackle planetary-scale problems. Yaghi’s company Atoco, founded in 2020, frames its mission simply – “from molecule to society”. That means starting with atomic architecture and ending with solutions a city like Phoenix or a factory in Mumbai can deploy.
Two flagship applications drive most of the current Research effort. The first is harvesting drinking water from dry air, even where humidity falls below 20 percent, such as Nevada’s deserts. The second is capturing carbon dioxide directly from ambient air or from industrial exhaust, then releasing it in a concentrated stream ready for reuse or safe storage. Both processes lean on the same core ability: selective absorption in billions of tiny pores.
From COF‑999 to desert water harvesters: what the devices do
On the climate front, one of the star materials is COF‑999, a covalent organic framework optimised to latch onto CO₂ at very low concentrations. In tests at Berkeley, COF‑999 cycled through more than 100 capture-and-release rounds without losing performance. That durability positions it for industrial carbon-capture modules as well as smaller units fitted to commercial buildings.
For water, the story is even more visceral. Yaghi’s MOFs can pull thousands of litres per day from the air when packed into modular harvesters. These units absorb vapour during cooler night hours. With morning sunlight, the frameworks gently warm and release liquid water, cutting electricity needs. Dedicated coverage such as this report on Nobel-winning water technology shows how closely this Innovation is tied to real-world thirst.
Inside the technology: how a “super-sponge” actually works
To understand the Technology, picture a skyscraper built from chemistry instead of steel. The metal ions are junctions, the organic molecules act as beams, and the gaps become precise nano-rooms. By adjusting geometry, chemists decide which guest molecules fit, how tightly they bind and how much energy is needed to let them go again.
Yaghi often compares his synthesis style to cooking: never more than three steps and only “healthy ingredients”. First comes the choice of backbone. Second, the pore size and internal chemistry. Third, integration into a device where air or flue gas flows through, and target molecules dock inside. The brilliance lies in doing this with scalable, relatively simple reactions rather than lab‑only artistry.
Energy, sustainability and the problem of “waste materials”
Plenty of gadgets claim green credentials while hiding heavy energy or waste footprints. Reticular materials try to address that head-on. Many MOF-based water harvesters unlock their captured water using ambient sunlight instead of compressors. Carbon-capture units can tap low-grade waste heat from industrial processes rather than demand fresh power, boosting Sustainability and economics at once.
End-of-life design is another quiet advantage. Yaghi’s team has developed routes where spent MOFs are disassembled in water, leaving no persistent microparticles drifting in the environment. In a world scaling production to multi-tonne volumes, that proactive “no MOF waste problem” stance may matter as much as performance metrics.
Scientific significance: redefining what materials can do for society
Chemists sometimes talk about “ages” of materials: stone, bronze, iron, silicon. Supporters of reticular chemistry argue that MOFs and COFs could mark another turn of the wheel, especially as they cross from niche labs to global infrastructure. The field has not plateaued; patent filings and publications continue to climb more than three decades after the first frameworks.
Part of the excitement comes from new frontiers beyond water and CO₂. MOF-based catalysts already rival natural enzymes in accelerating reactions yet promise longer lifetimes and easier recovery. Drug manufacturers, for instance, are eyeing these frameworks to streamline pharmaceutical synthesis and reduce solvent waste, connecting abstract crystal design to affordable medicines.
Multivariate frameworks, AI design and the next wave of innovation
Inside Yaghi’s Berkeley lab, one of the most daring directions is “multivariate” materials. Instead of one repeating environment, a single crystal hosts many different nano-zones, each decorated with distinct chemical groups. Gas molecules encounter a sequence of tailored microenvironments, increasing selectivity and efficiency in ways traditional materials cannot match.
Designing such complexity by hand would be slow. That is why the group now uses large language models and other AI agents to propose promising structures. Early trials doubled the rate of new MOF discovery. This hybrid of human intuition and algorithmic search is already noted in several analyses, including features like New Scientist’s deep dive into his work or broader technology roundups on platforms such as this overview of transformative inventions.
From Nobel lecture to global impact: why this matters on Earth
During his Nobel banquet speech, Yaghi framed his work as a celebration of possibility, not just recognition. That perspective matters when communities facing daily water shortages or pollution look at high-end chemistry. For them, the question is simple: does this Innovation translate into cheaper, more reliable access to basic needs?
Real-world pilots suggest a steady move in that direction. Think of a fictional town, Almera, perched on the edge of a desert and reliant on expensive tanker deliveries. A cluster of MOF-based harvesters on school roofs could give the town a new, local source of clean water. At the same time, compact COF‑999 modules mounted on nearby cement plants start trimming emissions without costly retrofits. That kind of dual Transformation – water resilience plus climate action – explains why commentators describe Yaghi’s work as poised to “change the world”.

What exactly is Omar Yaghi’s groundbreaking invention?
His breakthrough lies in creating programmable crystalline materials called metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). These ultra-porous ‘super-sponges’ can be tailored at the molecular level to capture and release specific molecules, such as water from dry air or carbon dioxide from polluted gases, enabling devices that tackle real-world challenges like water scarcity and climate change.
How can MOFs turn desert air into drinking water?
MOF-based devices expose a large internal surface area to the air. At night, the frameworks absorb water vapour even when humidity is very low. When heated by morning sunlight or a small energy input, they release that water as liquid into a collection chamber. Repeating this cycle daily allows thousands of litres of potable water to be produced with modest energy use.
Why did Omar Yaghi receive the Nobel Prize in Chemistry?
Yaghi was honoured in 2025 for founding reticular chemistry and pioneering MOFs and COFs. He demonstrated that solids can be built like molecular Lego, with precisely designed pores and structures. This approach opened vast new possibilities for gas storage, separation, catalysis and environmental applications, shifting how chemists think about designing materials from the atomic scale upward.

Pilot systems exist for water harvesting in arid regions and for capturing carbon dioxide in industrial settings. Some companies are integrating these frameworks into modular units for buildings or factories. Large-scale deployment is still emerging, but the combination of improved performance, durability and falling production costs suggests broader adoption over the coming decade.
What makes these materials environmentally sustainable?
Many MOF and COF devices operate on low-grade heat or sunlight instead of energy-intensive compressors. Their long operational lifetimes reduce replacement waste, and some formulations can be safely disassembled in water at the end of life, avoiding persistent micro-material pollution. This lifecycle approach aligns with broader goals to cut emissions, protect ecosystems and conserve resources.
