Who Wins the 2026 Chemistry Nobel? Three Picks, and the One Made on a Bench

Next Wednesday morning in Stockholm, the Royal Swedish Academy of Sciences will name the 2026 Nobel laureates in chemistry. Nobody outside the committee knows who it will be, and the nominations stay sealed for fifty years. What exists in the meantime is a well-known guessing game, and its most closely watched entry was published on 17 September, when the analytics company Clarivate released its annual Citation Laureates: researchers whose papers are cited so heavily that Clarivate calls their work “of Nobel class.”

This year’s chemistry list has three entries. One is about how electrons travel through proteins. One is a set of gene-editing tools. And one is a technique that starts with a slide of gold and a bottle of solvent. That last one, self-assembled monolayers, is the reason this article exists: it is the only pick on the list that most readers could set up on a lab bench with reagents from an ordinary chemical catalog, and the grade of those reagents is the part a buyer can actually act on.

This is an explainer, not a prediction. We have no view on who the committee will choose, every name and quotation below comes from Clarivate, Chemistry World or the Nobel Foundation, and every paper cited is listed at the end.

When the 2026 chemistry Nobel is announced

The Nobel Foundation’s 2026 schedule runs from 5 to 12 October. Chemistry is the third announcement of the week:

The chemistry prize is announced by the Royal Swedish Academy of Sciences from its session hall in Stockholm and streamed live on the Nobel Prize’s own channels. “At the earliest” is the Foundation’s wording: the announcement starts when the Academy’s meeting ends, which can run late.

Clarivate’s three chemistry picks

Clarivate named 22 Citation Laureates across chemistry, physics, medicine and economics on 17 September 2026. The chemistry entries, with the citation wording Clarivate published, are:

Clarivate’s own description of the list is measured. “For more than two decades, Citation Laureates has been among the world’s most closely watched data-led indicators of exceptional research influence,” said Bar Veinstein, President, Academia & Government at Clarivate. The method counts how often a researcher’s papers are cited by other researchers. It measures influence, which the committee also weighs, but it does not see the nominations, so it is a citation signal, not a forecast. Clarivate’s track record is real, 89 later laureates since 2002, but many of those wins came years after the name first appeared.

What a self-assembled monolayer is

A self-assembled monolayer is a film exactly one molecule thick that builds itself. You take a molecule with a “head” that bonds to a particular surface and a long “tail” that does not, dissolve it, and put a clean surface in the solution. The heads attach, the tails crowd together and stand up, and within hours the surface is covered by an ordered, closely packed carpet whose top face is whatever chemistry you put on the end of the tail. Change the end group and the same gold slide becomes water-repellent, water-loving, sticky to proteins, or resistant to them.

Two head-group families did most of the work, and they map onto the two halves of Clarivate’s citation:

• Silanes on oxides. In 1980 Jacob Sagiv published “Organized monolayers by adsorption. 1. Formation and structure of oleophobic mixed monolayers on solid surfaces” in the Journal of the American Chemical Society. Long-chain trichlorosilanes such as octadecyltrichlorosilane react with the hydroxyl groups on glass and oxidized silicon and lock into a cross-linked film. Silane films are still how many glass and silicon parts are made water-repellent today.
• Sulfur on gold. In 1983 Ralph Nuzzo and David Allara, then at Bell Laboratories, published “Adsorption of bifunctional organic disulfides on gold surfaces” in the same journal. Sulfur bonds strongly to gold, gold does not oxidize in air, and the result became the most studied model surface in the field: alkanethiols on gold.

The reason the work is cited so heavily is that it is everywhere. SAMs are the surface chemistry under many biosensors, the anti-stick layer on nanoimprint lithography stamps, the coatings that protect micro-electromechanical parts, and the “ink” in microcontact printing. The 2005 Chemical Reviews survey by Love, Estroff, Kriebel, Nuzzo and Whitesides, titled “Self-Assembled Monolayers of Thiolates on Metals as a Form of Nanotechnology,” runs to 68 pages and is itself heavily cited.

How a SAM is made: the bench version

The standard thiol-on-gold recipe, as the 2005 Love review describes it, immerses a freshly prepared or cleaned substrate in a dilute (about 1–10 mM) ethanolic solution of the thiol for about 12–18 hours at room temperature. The surface is mostly covered within minutes; the long soak lets the film order itself. Many other solvents work, and silane films on oxide are usually made from a dry hydrocarbon solvent instead, because water in the solvent makes trichlorosilanes polymerize in the bottle rather than on the surface.

Every step around that soak involves a commodity chemical:

What this means on a specification

If you are buying for surface work, monolayers or otherwise, these are the lines on a certificate of analysis that matter. ACS reagent grade means the lot meets the American Chemical Society’s published specification for that reagent; technical grade means it meets a commercial specification that may not list these impurities at all.

Whether any of these is right for a given monolayer protocol is the protocol’s call, not ours. Read the method’s reagent section, compare it to the certificate of analysis, and if the method names a grade, buy that grade. We will tell you honestly if what we carry does not match it.

The other two picks, briefly

Long-range electron transfer in proteins. Many of life’s energy reactions, from respiration to photosynthesis, depend on electrons moving between metal centers buried inside proteins, sometimes more than a nanometre apart. Harry Gray and Jay Winkler at Caltech measured how fast that happens by attaching ruthenium complexes to the surfaces of proteins such as azurin and cytochrome c, firing a laser pulse to start the transfer, and timing it. Their results showed how electrons tunnel through the protein structure itself, and that the path through the protein matters, not just the distance. Their 2003 review, “Electron tunneling through proteins,” summarizes the program.

Base and prime editing. CRISPR-Cas9 cuts both strands of DNA, and the cell’s repair of that cut is messy. In 2016 David Liu’s group at Harvard published a way to change a single DNA letter without a double-strand cut, fusing a disabled Cas9 to an enzyme that converts one base into another. The paper, “Programmable editing of a target base in genomic DNA without double-stranded DNA cleavage,” appeared in Nature. Prime editing, from the same lab in 2019, extended the idea to small insertions and deletions.

Neither of those two has a catalog angle, and we are not going to invent one. They are on this page because they are on Clarivate’s list.

Common questions

When is the 2026 Nobel Prize in Chemistry announced?

On Wednesday 7 October 2026, at 11:45 CEST at the earliest, by the Royal Swedish Academy of Sciences in Stockholm. That is 4:45 a.m. US Central and 5:45 a.m. Eastern. The announcement is streamed live on the Nobel Prize’s official channels, and it can start later than scheduled if the Academy’s meeting runs long.

Who are the 2026 Clarivate Citation Laureates in chemistry?

Six researchers in three groups: David Allara, Ralph Nuzzo and Jacob Sagiv for self-assembled monolayers; Harry Gray and Jay Winkler of Caltech for long-range electron transfer in proteins; and David Liu of Harvard and the Broad Institute for base editing and prime editing. Clarivate published the list on 17 September 2026.

How accurate are Clarivate’s Nobel predictions?

Clarivate says 89 of its Citation Laureates since 2002 have later won a Nobel Prize, but often years after first being named. The list measures how heavily a researcher’s work is cited, not the committee’s deliberations, so it is a citation signal, not a forecast for any particular year.

What is a self-assembled monolayer?

A film one molecule thick that forms on its own when a clean surface is placed in a dilute solution of molecules whose head group bonds to that surface. Thiols on gold and silanes on glass or silicon oxide are the two classic systems. The exposed end of each molecule sets the surface’s properties, such as whether it repels water.

What solvent is used to make a self-assembled monolayer?

For thiols on gold, usually ethanol, at about 1–10 mM thiol for 12–18 hours according to the 2005 Love review, though many solvents work. For silanes on oxide surfaces, a dry hydrocarbon such as toluene is common, because water makes trichlorosilanes polymerize in solution instead of on the surface. Follow your protocol’s stated solvent and grade.

What is piranha solution used for?

Stripping organic contamination from glass, silicon and oxide surfaces before coating or bonding. It is a mixture of concentrated sulfuric acid and 30% hydrogen peroxide, it is hot and strongly oxidizing, and it reacts violently with organic material, so it is used only under a written laboratory procedure with proper ventilation and protective equipment.
