Scientists Build Micromotors Smaller Than Human Hair, Revolutionizing Medicine with Laser-Powered Gears
On September 18, 2025, researchers at the University of Gothenburg made a groundbreaking discovery in the field of micro-engineering by building micromotors smaller than a human hair. These tiny light-powered gears have the potential to revolutionize medicine by enabling the creation of machines that can interact with cells in unprecedented ways.
According to Science Daily, the researchers used laser light instead of traditional mechanics to power the micro-gears, which can spin, shift direction, and even propel small machines. The breakthroughs could soon lead to revolutionary medical tools working at the scale of cells. Each gear is approximately 0.016 mm in diameter, making them incredibly tiny.
The team's innovation involves using optical metamaterials that react to laser light, allowing the gears to move without traditional mechanical components. This technology has far-reaching implications for medicine, enabling the development of tiny machines that can interact with cells and potentially transform treatment options for various diseases.
"We are excited about the possibilities this breakthrough offers," said Dr. Gan Wang, lead researcher on the project. "Our goal is to create machines that can operate at the cellular level, which could revolutionize medical treatments."
The researchers' achievement builds upon previous work in micro-engineering and nanotechnology. According to Science Daily, the team's use of laser-powered gears paves the way for creating tiny machines that can interact with cells in unprecedented ways.
"This innovation has the potential to transform medicine by enabling the creation of tiny machines that can operate at the cellular level," said Dr. Wang. "We believe this technology could lead to breakthroughs in various medical fields, including cancer treatment and regenerative medicine."
The University of Gothenburg's research team is currently exploring the full potential of their discovery and working on scaling up the technology for practical applications. While it may take time for these innovations to reach the market, researchers are optimistic about the impact this technology could have on human health.
As Dr. Wang noted, "We are just beginning to scratch the surface of what's possible with laser-powered micromotors. The future looks bright for medical advancements driven by this innovative technology."
The development of laser-powered micromotors smaller than a human hair is a significant breakthrough in micro-engineering and nanotechnology. As researchers continue to explore the potential of this innovation, it is clear that its impact on medicine will be profound.
In related news, the University of Gothenburg has announced plans to establish a new research center focused on developing practical applications for laser-powered micromotors. The center will bring together experts from various fields to advance the technology and explore its potential in medical treatments.
As this story continues to unfold, one thing is certain: the discovery of laser-powered micromotors smaller than human hair marks a significant milestone in the pursuit of innovative medical solutions.
