For more than two decades, graphene has been one of the most celebrated materials in science. Researchers have touted its remarkable properties. It is stronger than steel, thinner than paper, highly conductive, and capable of enabling breakthroughs across electronics, sensing, energy storage, and advanced manufacturing. Yet despite years of excitement and billions of dollars invested globally, graphene has largely failed to deliver on its commercial promise.
According to Christopher DiMarco, the problem was never graphene itself.
“The challenge has always been manufacturing,” he says.
That realization became the foundation for Sindri Materials, a Delaware-based advanced materials company focused on producing ultra-high-quality graphene at scale. DiMarco has spent more than a decade focused on a deceptively simple question: What does it take to manufacture graphene consistently enough that industries can actually depend on it?
The answer, he believes, requires rethinking the entire production process.
From Research Question to Company Mission
DiMarco’s path to entrepreneurship began during his Ph.D. research at Columbia University. Originally, his work focused on studying the mechanical properties of synthesized graphene. But as he dug deeper into the material, he encountered a more fundamental problem.
Researchers did not fully understand how graphene synthesis itself worked.
“After a lot of experiments trying to understand synthesis, I realized we didn’t understand much about synthesis,” DiMarco recalls.
That realization launched years of research into controlling graphene growth and understanding the variables that determine quality. The work eventually culminated in a landmark Nature publication that drew on more than a decade of experimentation and multiple generations of researchers.
Yet even after completing his academic work, DiMarco felt there was still more to uncover.
Years after finishing his Ph.D., he continued developing ideas about how graphene manufacturing could be improved. Those ideas ultimately became the foundation for Sindri Materials.
Rather than viewing graphene as a commodity material, DiMarco saw an opportunity to build a company around quality itself.
An End-to-End Approach
One of the defining characteristics of Sindri is its commitment to controlling every stage of production.
Many companies focus on a single piece of the manufacturing puzzle. Sindri instead designs its manufacturing systems, develops the production recipes that determine graphene quality, and creates fabrication methods that preserve that quality throughout the process.
For DiMarco, those pieces cannot be separated.
“We take an end-to-end control approach,” he explains.
That philosophy stems from a belief that graphene’s performance is directly tied to how it is manufactured and handled. Small imperfections introduced anywhere in the process can undermine the material’s advantages.
That emphasis on precision may sound obsessive, but DiMarco believes it is necessary if graphene is ever going to achieve its long-promised potential. To fully unlock the material’s capabilities, he argues, manufacturers may need to rethink existing production methods rather than simply adapting legacy semiconductor processes.
“You might be able to leverage ten percent of graphene’s performance,” he says. “But you’re not going to reach that eighty to ninety percent performance that can really have a big impact.”
Finding the Right Beachhead Market
Like many deep-tech founders, DiMarco faced a common challenge early in Sindri’s development. The company had a promising technology platform, but identifying the right initial market was just as important as building the technology itself.
Many graphene startups have focused on batteries or semiconductors, but Sindri chose a different path. The company’s first commercial market is structural biology, specifically cryogenic electron microscopy, or cryo-EM.
Cryo-EM has become one of the most important tools in modern biological research, allowing scientists to visualize proteins and molecular structures at near-atomic resolution. The technique has transformed drug discovery and earned its inventors the Nobel Prize in Chemistry.
For years, researchers have known that incorporating graphene into cryo-EM sample preparation can significantly improve imaging quality. The challenge has been obtaining graphene that meets the demanding standards required for consistent performance.
That is where Sindri saw an opportunity.
Structural biology offered a rare combination of technical validation, manageable manufacturing scale, and immediate market demand.
“Structural biology ended up being this diamond in the rough,” DiMarco says.
The market allows Sindri to commercialize its technology, generate revenue, and establish credibility while building the same manufacturing foundation required for future applications in electronics and sensing.
Just as importantly, cryo-EM grids are consumable products. Laboratories continually purchase new grids, creating recurring demand that can support growth without requiring massive manufacturing infrastructure from day one.
Moving Beyond the Graphene Bubble
Graphene’s history has not been without challenges.
DiMarco acknowledges that the industry experienced a wave of hype during the mid-2010s. Many companies promised revolutionary products, but inconsistent quality standards and limited verification left customers uncertain about what they were actually buying.
As a result, some potential customers became skeptical of graphene altogether.
Today, DiMarco believes the industry has matured considerably. Better standards, improved manufacturing methods, and more rigorous validation are helping separate real technological advances from marketing claims.
Still, he recognizes that credibility must be earned through data.
At Sindri, customer conversations begin with measurable results.
“We’re data first,” he says. “Data and reproducibility in that data.”
That philosophy has proven especially effective within the cryo-EM community, where researchers can immediately see the difference between high-quality graphene and inferior alternatives.
For scientists whose experiments depend on imaging delicate biological structures, reliability is not a luxury. It is a necessity.
Building the Future of Advanced Materials
While structural biology represents Sindri’s first market, DiMarco sees a much larger opportunity ahead. If graphene manufacturing can be mastered, he believes the technology could transform fields ranging from sensors and electronics to photonics and biosensing.
Among the most promising near-term opportunities are advanced sensing technologies and next-generation electronics, areas where graphene’s unique properties can provide immediate advantages. Longer term, DiMarco envisions even broader possibilities.
For DiMarco, these possibilities are what makes the challenge worthwhile. Graphene’s potential has never been the question. The question is whether someone can build the manufacturing foundation needed to realize it.
Sindri Materials is betting that the answer is yes.
