Berkeley's MOFs: Water, Carbon & Drug Delivery Platform
16 Jul 2026
A crystalline material with an unusually wide reach
A class of crystalline solids called metal-organic frameworks (MOFs) is drawing attention for its ability to do three very different things: trap greenhouse gases, act as a nanosized drug carrier, and pull water out of desert air. The underlying science, known as reticular chemistry, was pioneered by Berkeley chemist Omar Yaghi, who began combining metals with organic molecules roughly 20 years ago to found the field.
The structural property that makes MOFs useful is their extraordinary surface area — a single gram of MOF material, if unfolded and spread flat, could reportedly cover a football field. That density of surface area is what allows the material to be tuned for wildly different jobs, from capturing molecules of water vapor to trapping CO2 or ferrying chemotherapy drugs to cancer cells.
From concept to (partial) commercialization
Yaghi and his Berkeley team conceived a MOF specifically designed to harvest water from extremely dry air back in 2014. Engineers at MIT designed the harvester apparatus that pairs with the material, and each pound of MOF powder is said to collect about 1.3 liters of water every 12 hours. Yaghi's team is now working with unnamed companies to commercialize this water-harvesting technology, though the report does not specify which partners are involved or when a commercial product might reach market.
Beyond water harvesting, MOFs are being explored for:
- Carbon capture — mining CO2 from flue gases inside coal-fired power plants before it reaches the atmosphere.
- Drug delivery — biodegradable MOFs are being used by medical researchers to carry chemotherapy drugs directly to cancer cells.
- Pesticide delivery — MOFs may allow pesticides to be delivered more safely and effectively in agricultural settings.
Yaghi's contributions to this chemistry have been recognized with the King Faisal International Prize (2015), the Albert Einstein World Award of Science (2017), and the Wolf Prize in Chemistry (2018).
The scale of the design space
There are currently about 20,000 different kinds of MOFs, according to the report — a number that underscores both the versatility of the underlying chemistry and how much of that design space likely remains unexplored for specific commercial applications.
What's still missing
Several important gaps remain unaddressed in the current reporting:
- No information on which companies are partnering with Yaghi's team for commercialization.
- No cost or scalability data for producing MOFs at industrial volumes.
- No details on energy requirements or process efficiency beyond the stated water-harvesting rate.
- No regulatory or safety data on human trials for chemotherapy-carrying or pesticide-delivery MOFs.
- No timeline for when a commercial water-harvesting product might launch.
- No comparison data on how MOF-based carbon capture performs against existing capture technologies.
Risks to watch
The technology remains at a commercialization/partnership stage rather than being a proven, market-ready product. Biodegradable and pesticide-delivery MOF applications may also face regulatory hurdles that aren't addressed in current reporting, and questions about the scalability and manufacturing cost of MOFs for industrial-scale carbon capture or water harvesting remain open.
Why founders should care
For early-stage founders in cleantech, agtech, or biotech, MOFs likely represent several distinct startup verticals rather than a single market opportunity — climate applications (water and carbon), agricultural applications (pesticide delivery), and health applications (targeted drug delivery) each carry different regulatory and go-to-market paths. The fact that Yaghi's team is actively collaborating with companies suggests near-term licensing or partnership opportunities may be available for founders positioned in materials science or cleantech, though the specific companies involved aren't disclosed.
With roughly 20,000 MOF variants already in existence, founders will probably need specialized technical expertise to differentiate a specific formulation or application rather than treating MOFs as a generic material. And given the absence of published cost or scalability data, founders considering a MOF-based business case should plan to independently validate manufacturing feasibility before committing significant capital — the gap between lab-scale promise and industrial-scale economics remains, at this point, unquantified.
