Imagine robots so small they could navigate the human bloodstream, delivering life-saving drugs with pinpoint accuracy. This isn’t science fiction—it’s the cutting-edge world of modular microrobots. These tiny machines, built from interchangeable units, can adapt their size, shape, and function to tackle a variety of tasks. From targeted drug delivery to autonomous micromanufacturing, the possibilities are endless. But creating hundreds of identical robots, each no larger than a red blood cell, comes with its own set of challenges.
“At this scale, robots are not big enough to hold a microcontroller to tell them what to do,” explains Taryn Imamura, a Ph.D. candidate in Carnegie mellon University’s Department of Mechanical Engineering. “Active colloids—the robots—have what we call embodied intelligence. Their behavior, including how fast they move, is resolute by their size and shape. But as they get smaller, it becomes increasingly difficult to ensure uniformity in their structure.”
in a groundbreaking study published in Advanced Materials technologies, Imamura and her team have developed a method to control the size and structure of these active colloids while producing over 100 times more units than previous techniques. By using physical templates made from materials like polycarbonate and polystyrene, they’ve achieved precise control over the robots’ body plans and module arrangements. This innovation not only streamlines production but also opens the door to studying how these microrobots behave in large groups.
“By leveraging the material properties of the templates, we’ve addressed key manufacturing challenges,” Imamura says. “Now, we can produce these structures in bulk and explore their dynamics and functionality at the population level. This technology could help us answer many questions about how colloidal microrobots operate and interact.”
Supported by undergraduate researcher Nicholas Chung and co-advised by Rebecca Taylor and Sarah Bergbreiter, Imamura’s work has paved the way for more complex microstructures. These include microrobots designed for targeted drug delivery and micro rotors for applications like microfluidic mixing. The use of high-surface-energy materials ensures that the robots’ geometry remains consistent, even as their numbers grow.
This breakthrough isn’t just a step forward for robotics—it’s a leap toward a future where microscopic machines could revolutionize medicine, manufacturing, and beyond. As researchers continue to refine these technologies, the potential applications are as vast as the challenges are small.
In a groundbreaking growth, researchers have engineered microscopic robots using DNA nanostructures, creating a new class of flexible and responsive microrobots. These tiny machines, known as active colloids, are designed to adapt to their surroundings and perform precise tasks, such as delivering drugs to targeted areas within the body.
The team’s innovative approach involves linking the colloids with compliant DNA structures, which not only enhance their agility but also allow them to respond to external signals. by leveraging biopolymers like DNA, the researchers have integrated advanced sensors into the robots, effectively transforming them into mobile micro-laboratories.
“We’ve demonstrated that the DNA in our microrobots enables them to execute specific actions—like controlled disassembly—when exposed to various stimuli,” explained one of the lead researchers. “Imagine a microswimmer transporting medication to a precise location in the body. Upon arrival,it receives a signal to disassemble,ensuring the drug remains exactly where it’s needed.”
This breakthrough not only advances the field of microrobotics but also makes the technology more accessible to a broader range of scientists. “By creating uniform populations of active colloids that are flexibly linked, we’ve substantially lowered the barrier to entry for this type of research,” said Imamura, a key contributor to the project.”Encouraging collaboration among researchers from diverse backgrounds will undoubtedly accelerate progress in this complex field.”
The potential applications of these microrobots are vast, ranging from targeted drug delivery to environmental monitoring. As the technology evolves, it could revolutionize how we approach medical treatments and scientific exploration on a microscopic scale.
This research represents a significant step forward in the integration of nanotechnology and robotics,paving the way for future innovations that could transform industries and improve lives.
