Staple-like particles reveal new path to strong materials

Staple-like particles reveal new path to strong materials alse6588 Tue, 04/14/2026 - 11:18

A tightly packed ball of office staples can be surprisingly strong.Try to pull it apart and the tangled metal resists like a solid object.

But with the right movement or vibration, that same bundle can quickly fall back into loose pieces.

A team of engineers and materials scientists in the Paul M. Rady Department of Mechanical Engineering at �鶹��Ƶ are exploring how this uncanny combination of strength and flexibility could inspire a new class of materials built on interlocking particles. By mimicking the way staples lock together and release, the researchers believe these emerging materials can one day form structures that are strong, adaptable and even recyclable.

“We’ve been playing around with the idea of building blocks and geometry for many years, but we started looking at interlocking, entangled particles only recently,” said Professor Francois Barthelat, the leader of the Laboratory for Advanced Materials & Bioinspiration. “We are excited about the combination of properties we can get out of these systems and we believe this technology has the potential to go in many directions.”

Unraveling the research

A bird nest made out of interwoven sticks and fibers.

The work, recently published in the Journal of Applied Physics, focuses on what the researchers call “entanglement”—when multiple particles become intertwined with one another, creating a link.

It’s not a new concept. In fact, nature is filled with examples of objects or materials that tangle and interlock with each other to create strong structures. Think about that giant bird nest on the tree in your neighborhood made out of interwoven sticks and fibers, or the interplay of hard minerals and soft proteins in your bones.

But how can scientists recreate that kind of natural entanglement in manufactured materials? The researchers in Barthelat’s lab say the answer revolves around one key concept: particle shape.

“Let’s take sand as an example. Sand is smooth and convex-shaped, meaning it cannot interlock from grain to grain,” PhD student Youhan Sohn said. “However, we found that if we change the shape of a grain of sand, we can drastically affect its behavior and mechanical properties, including the particle’s ability to link with other particles.”

Once the group came to this realization, they began running Monte Carlo simulations, a type of computational analysis, to predict exactly how the particles interlock with each other. Their goal was to find the optimal geometry that delivered the maximum entanglement.

After finding the optimal shape, the team performed pickup tests to see how the entangled particles actually behaved.

The tests showed that a “two-legged” particle—similar in shape to a staple—had the greatest potential for entanglement. But the researchers also discovered several unexpected advantages that made the design even more intriguing.

The first was its rare blend of tensile strength and toughness, a combination the researchers say conventional materials rarely achieve simultaneously.

“Our entangled granular material using the staple-like particle demonstrates both high strength and toughness at the same time,” said PhD student Saeed Pezeshki.

Next, was its unique ability to rapidly assemble—and just as quickly come apart.

By applying different vibrational patterns to the material, the team was able to change its level of entanglement on demand. A light vibration, for example, could be used to interlock and strengthen the particles, while a larger vibration could cause them to completely unravel.

“It’s a strange material because it’s obviously not a liquid. However, it’s also not quite solid. This opens new and intriguing engineering possibilities,” Barthelat said. “Handling a bundle of these entangled particles feels very remote and exotic.”

Reassembling the impact

One of those possibilities comes in the realm of sustainability. The group believes that one day, large buildings and structures like bridges can be designed using entangled materials, allowing them to be disassembled when no longer needed or even fully recycled.

Or maybe entangled materials can make their way into the world’s next great robotic systems, sort of like the ones you’ve seen in some of your favorite sci-fi movies.

“I was talking with other students who believe this technology can be used in swarm robotics— where small robots can entangle, do a task and then disentangle when they are done,” said Pezeshki.

“Yes, kind of like that liquid metal T-1000 in Terminator 2 who can change shape to slide under a door and then transform back to a human’s size on the other side,” added Barthelat. “It’s expensive and scaling up is a challenge, but it’s something that’s on everybody’s mind.”

For now, the group is focused on building out the next phase of their research. They are currently testing a new particle shape with added protruding “legs”—similar to those spiky plant burrs that stick relentlessly to your shoes when you step on them—which they believe can generate even stronger entanglement properties.

But no matter what project they are working on, the team says the most important thing about their work is maintaining the passion and excitement.

“We’re not quite sure where this is going to go, but we’re going to continue the fun,” Barthelat said. “Most people don’t think about making strong materials in this way out of something like staples, because they think it’s counterintuitive. Until they try breaking a bundle of staples in half and see that it’s impossible.

“We love to take a difficult project like this and dig in.”

Roughly 6.8 million people donate blood in the United States alone, helping save millions of lives, according to the American Red Cross. But just like groceries sitting on store shelves, red blood cells age over time. That's why Associate Professor Xiaoyun Ding and medical collaborators at CU Anschutz have created a new chip device to help give blood centers and hospitals a reliable way to monitor the quality of red blood cells after they sit for weeks in storage.
