20 Trends in Chemistry

20 Trends in Chemistry Shaping the Future

Chemistry is changing rapidly. New technologies are allowing scientists to design molecules with artificial intelligence, capture carbon dioxide directly from the atmosphere, create new materials atom by atom and automate experiments that once required hours of manual laboratory work.

At the same time, some of the biggest challenges facing society — climate change, clean energy, sustainable manufacturing, disease and plastic waste — are fundamentally chemical problems.

The International Union of Pure and Applied Chemistry (IUPAC) publishes an annual selection of emerging technologies with the potential to create new opportunities in chemistry and address major global challenges. Its 2025 selection included technologies ranging from direct air capture and single-atom catalysis to synthetic cells and AI models for determining molecular structures.

For students considering studying chemistry, these developments show just how broad the subject has become. Here are 20 important trends in chemistry that could help shape science, industry and everyday life in the years ahead.

1. Artificial Intelligence in Chemistry

Artificial intelligence is becoming an increasingly important tool for chemists.

Researchers can use AI and machine learning to analyse enormous datasets, identify patterns and make predictions about molecules and chemical reactions. Current applications include molecule screening, reaction prediction, structure determination and automated experimentation.

This could allow researchers to investigate promising compounds before spending considerable time and resources producing them experimentally.

For future chemists, this also means that chemistry and computer science are becoming increasingly connected.

2. Self-Driving Laboratories

What if a laboratory could decide which experiment to perform next?

Self-driving laboratories combine robotics, automated equipment and artificial intelligence. Algorithms can propose experiments, laboratory equipment can carry them out and the resulting data can inform what should happen next.

The technology has progressed from relatively narrow automation systems towards more sophisticated discovery platforms capable of proposing, executing and interpreting experiments with limited human intervention.

Rather than replacing chemists, these systems could allow researchers to investigate much larger experimental spaces while concentrating their attention on the questions, interpretation and creative thinking behind the research.

3. Green Chemistry

One of chemistry's biggest trends is also one of its broadest: making chemical processes more sustainable.

Green chemistry involves designing products and processes that reduce hazardous substances, waste and environmental impact.

That can mean finding safer solvents, using renewable starting materials, designing reactions that require less energy or creating catalysts that produce fewer unwanted by-products.

Sustainability and circularity continue to feature prominently in IUPAC's emerging-technology work, reflecting chemistry's increasingly important role in developing lower-impact technologies.

4. Direct Air Capture

Reducing future carbon emissions is one challenge. Removing carbon dioxide that is already in the atmosphere is another.

Direct air capture (DAC) uses chemical processes to separate CO₂ from ambient air. The captured carbon can then potentially be stored or used as a raw material.

The chemistry is challenging because carbon dioxide makes up only a relatively small proportion of the atmosphere, meaning capture materials need to operate efficiently and ideally be regenerated without consuming excessive amounts of energy.

IUPAC selected direct air capture as one of its Top Ten Emerging Technologies in Chemistry for 2025.

5. Electrochemical Carbon Capture and Conversion

Another emerging approach does not simply capture carbon dioxide — it seeks to transform it.

Electrochemical carbon capture and conversion uses electricity and chemical reactions to capture CO₂ or convert it into potentially useful products.

If these processes can be powered efficiently using low-carbon electricity, they could contribute to technologies that treat carbon dioxide as a chemical feedstock rather than simply a waste product.

The technology was another of IUPAC's 2025 emerging-technology selections.

6. Better Battery Chemistry

The transition towards renewable energy and electric transport depends heavily on chemistry.

Lithium-ion batteries have transformed portable electronics and electric vehicles, but researchers continue to investigate alternative battery chemistries that could offer advantages in cost, safety, energy density, charging or resource availability.

Solid-state batteries, for example, replace conventional liquid electrolytes with solid materials and have been recognised by IUPAC among important emerging chemical technologies. Sodium-ion batteries have also attracted attention as an alternative chemistry using a more abundant element. (iupac.org)

Energy storage is likely to remain one of the most important areas where chemistry affects everyday technology.

7. Hydrogen and Alternative Fuels

Hydrogen has long been discussed as a potential energy carrier, but producing it sustainably remains an important chemical challenge.

Researchers are investigating better catalysts and electrochemical processes for producing hydrogen using renewable electricity.

Chemists are also exploring solar fuels and other methods of storing renewable energy in chemical bonds.

The challenge is not simply discovering reactions that work. They also need to become efficient, scalable and economically practical.

8. Single-Atom Catalysis

Catalysts allow chemical reactions to happen faster or under more favourable conditions without being consumed in the process.

Single-atom catalysts take this idea to an extraordinary scale by dispersing individual metal atoms across a supporting material.

Using individual atoms can potentially maximise how efficiently expensive catalytic materials are used while creating unusual chemical properties.

IUPAC included single-atom catalysis among its top emerging technologies for 2025.

Developments like this demonstrate how controlling matter at increasingly small scales can transform chemical reactions.

9. Carbon Dots

Carbon dots are tiny carbon-based nanoparticles with interesting optical and electronic properties.

Their ability to fluoresce has created interest in applications including sensing, imaging, energy and materials science.

They are another example of how nanochemistry allows scientists to create properties that would not necessarily be expected from the same material at a larger scale.

Carbon dots appeared in IUPAC's 2025 emerging technologies list.

10. Advanced Chemical Sensors

Detecting extremely small quantities of a substance can be crucial in medicine, environmental monitoring and food safety.

Advances in nanotechnology are helping chemists develop increasingly sensitive chemical and biological sensors.

One emerging example is the nanochain biosensor, included in IUPAC's 2025 selection.

Future sensors could make it possible to identify biomarkers, pollutants or other substances more rapidly and at lower concentrations, potentially changing how diseases and environmental risks are monitored.

11. Synthetic Cells

Can scientists construct systems that reproduce some of the characteristics of living cells?

That is the question behind synthetic cells.

Researchers are attempting to build simplified cell-like systems from biological and chemical components, allowing them to investigate some of the fundamental processes associated with life.

The field sits at the intersection of chemistry, biology, biotechnology and materials science and was selected by IUPAC as an emerging technology in 2025.

Studying synthetic cells could deepen our understanding of biology while eventually contributing to new medical or biotechnological applications.

12. Chemical Biology and Targeted Medicines

The boundary between chemistry and biology is becoming increasingly blurred.

Chemical biologists design molecules that interact with biological systems, helping researchers investigate how cells work and develop new approaches to treating disease.

One example is targeted protein degradation, where molecules are designed to encourage cells to remove particular proteins. IUPAC previously highlighted the approach among its emerging technologies.

Instead of simply blocking the activity of a disease-associated protein, future treatments may increasingly manipulate the cellular machinery responsible for controlling it.

13. New Approaches to Drug Discovery

Developing a medicine can involve investigating enormous numbers of possible molecules.

Chemistry is increasingly combining automation, computational modelling, AI and advanced screening to narrow that search.

Machine-learning systems can help identify promising molecular candidates, while automated laboratories can test hypotheses more rapidly. Nature notes that AI is already being used in chemical research for molecule screening and reaction prediction.

The long-term opportunity is not simply faster drug discovery, but potentially a more systematic way of deciding which chemical possibilities deserve experimental attention.

14. Materials Informatics

Finding a new material traditionally requires a great deal of experimentation.

Materials informatics combines chemistry, materials science, large datasets and machine learning to make that search more targeted.

Machine learning is already being used to accelerate materials discovery, optimise synthesis and processing, and investigate relationships between a material's structure and its properties. Applications span areas including energy, catalysis, semiconductors and nanomaterials.

Future chemists may therefore spend as much time analysing data and computational models as they do working at a laboratory bench.

15. Smart and Responsive Polymers

We usually think of plastics and polymers as relatively passive materials.

But chemists are developing materials capable of changing their properties in response to their surroundings.

Thermogelling polymers, for example, can change their physical behaviour depending on temperature and were included among IUPAC's 2025 emerging technologies.

Responsive polymers could have applications in areas including medicine, drug delivery, tissue engineering and advanced manufacturing.

16. Chemical Recycling of Plastics

Plastic waste is one of the clearest examples of a problem chemistry helped create — and one chemistry may help solve.

Traditional mechanical recycling has limitations because plastics can degrade and mixed materials can be difficult to process.

Chemical approaches can instead attempt to break polymers back into smaller molecules or their original monomers, which may then be used to manufacture new materials.

IUPAC has previously highlighted both plastics-to-monomers technologies and depolymerisation among important emerging developments.

The wider goal is a more circular materials economy in which fewer valuable molecules are discarded after a single use.

17. Biological Recycling

Chemistry and biotechnology are also converging in the search for better ways to deal with plastic waste.

Certain enzymes and microorganisms can break down polymers, creating the possibility of biological recycling.

IUPAC highlighted biological recycling of PET among its 2023 emerging technologies.

The challenge is turning promising laboratory processes into systems capable of dealing with enormous quantities of real-world plastic efficiently and economically.

18. Additive Manufacturing and Advanced 3D Printing

3D printing is no longer only about producing simple plastic prototypes.

Additive manufacturing is expanding into sophisticated polymers, metals, composites and other functional materials, requiring chemists to understand and design substances specifically for different manufacturing processes.

IUPAC selected additive manufacturing as one of its emerging chemical technologies for 2025.

Chemistry is particularly important because the properties of the final object depend not only on its shape, but on how its constituent materials react, cure, bond and behave during printing.

19. Xolography

Some emerging technologies sound as though they belong in science fiction.

Xolography is an advanced approach to volumetric 3D printing in which light is used to solidify material into three-dimensional structures.

Unlike conventional layer-by-layer printing, volumetric approaches could potentially create complex objects within a volume of material.

IUPAC included xolography in its 2025 Top Ten, demonstrating the increasingly close relationship between photochemistry, materials science and advanced manufacturing.

20. Digital Chemistry and Better Chemical Data

Modern chemistry generates enormous quantities of data, but information is only useful if scientists and computers can understand and reuse it.

That is creating greater interest in digital standards, interoperable chemical data and FAIR data principles — making scientific information findable, accessible, interoperable and reusable.

IUPAC is working to translate chemical standards into the digital environment as open science and FAIR data become increasingly important.

Better chemical data could also make many of the other trends on this list more powerful. AI models, automated laboratories and materials-discovery systems all depend on high-quality information.

What Are the Biggest Trends in Chemistry Today?

Three themes connect many of these developments: artificial intelligence, sustainability and interdisciplinarity.

Chemistry is becoming increasingly computational. AI and machine learning can help researchers predict molecular behaviour, analyse experimental results and search chemical space more efficiently.

It is also becoming increasingly focused on sustainability. Carbon capture, battery technology, green chemistry and chemical recycling all demonstrate how chemists are working on technologies required for a lower-carbon and more circular economy.

Finally, the boundaries between scientific subjects are becoming less distinct. A researcher developing synthetic cells might combine chemistry with biology. Someone designing a new battery could work across chemistry, physics, engineering and materials science. A chemist using machine learning may also need programming and data-analysis skills.

IUPAC itself uses a broad definition of chemistry for its emerging-technology initiative, encompassing areas such as materials science, nanotechnology and biochemistry.

How Is AI Changing Chemistry?

AI is one of the most significant technological changes affecting chemical research.

The number of theoretically possible molecules is vastly larger than researchers could ever synthesise individually. Machine learning can help scientists navigate that enormous chemical space by identifying patterns and predicting which candidates might have useful properties.

AI is already being applied to structure determination, reaction prediction, molecular screening and automated experimentation.

Combined with robotics, it also creates the possibility of laboratories that can conduct cycles of prediction, experimentation and analysis increasingly autonomously.

For students, this means programming, statistics and data science could become increasingly valuable alongside traditional laboratory skills.

Why Is Green Chemistry Becoming More Important?

Almost everything we manufacture has a chemical footprint.

The materials used, energy consumed, solvents required, waste produced and fate of a product at the end of its life all affect its environmental impact.

Green chemistry asks whether these factors can be considered when a chemical process or material is designed, rather than attempting to deal with environmental problems afterwards.

That could mean using renewable feedstocks, reducing waste, replacing hazardous chemicals, designing recyclable materials or creating reactions that work at lower temperatures.

As industries attempt to reduce emissions and resource use, chemists will play an important role in determining whether more sustainable alternatives are technically possible.

What Does the Future of Chemistry Look Like?

The laboratory of the future may look quite different from the traditional image of a chemist surrounded by flasks and test tubes.

There will still be experiments. But alongside them could be robots performing repetitive procedures, AI models suggesting molecules, automated instruments collecting data and computational systems predicting the next experiment.

Chemists themselves may increasingly work across disciplines.

The same researcher might need to understand molecular interactions, analyse a dataset, work with engineers and consider the environmental consequences of taking a process from the laboratory to industrial scale.

That makes chemistry an increasingly broad field for students interested in solving practical problems.

Why Study Chemistry?

Chemistry sits between some of the biggest questions in modern science.

How can we store renewable electricity?

Can we remove carbon dioxide from the atmosphere?

How can medicines target diseases more precisely?

Can plastics become genuinely circular?

Could we design entirely new materials rather than relying on those found in nature?

And how might artificial intelligence change the way scientific discoveries are made?

Studying chemistry develops an understanding of matter at the molecular level, but it also introduces students to problem-solving, experimentation, mathematical reasoning and scientific analysis.

At Atlas Summer Courses, students interested in chemistry can explore the subject beyond the constraints of their usual school curriculum, investigate challenging ideas and consider where developments in modern chemical science could lead next.

Chemistry Is Becoming More Important, Not Less

Chemistry is sometimes imagined as an established science in which the fundamental discoveries have already been made.

The trends shaping the subject suggest the opposite.

Scientists are designing new catalysts atom by atom, building simplified synthetic cells, using algorithms to navigate enormous chemical spaces and developing new ways to capture carbon, recycle materials and store energy.

Some of these technologies may eventually become commonplace. Others may encounter scientific, economic or practical limitations.

That uncertainty is precisely what makes emerging chemistry interesting.

The next generation of chemists will not simply learn what molecules can do. They will help decide what we ask molecules to do next.
