Scientists Build Tiny Micromotors Smaller Than Human Hair Using Laser-Powered Gears
In a groundbreaking breakthrough, researchers at the University of Gothenburg have successfully built micromotors smaller than a human hair using laser-powered gears. These tiny machines can spin, change direction, and even propel small devices, opening up new possibilities for medical applications.
According to Science Daily, the researchers used laser light instead of traditional mechanics to power the micro-gears, which are made from silica and measure about 0.016 mm in diameter. This innovative approach allows for the creation of tiny machines that can interact with cells at an unprecedented level. "These breakthroughs could soon lead to revolutionary medical tools working at the scale of cells," said Gan Wang, a researcher involved in the project.
The development of these micromotors is significant because it enables the creation of tiny machines that can perform specific tasks within the human body. According to Science Daily, this innovation has the potential to transform medicine by enabling the creation of devices that can interact with cells in new and innovative ways. "This could potentially lead to breakthroughs in areas such as cancer treatment, where tiny machines could be used to deliver targeted therapies," said Dr. Wang.
The researchers built three different types of micro-gears, each with unique properties. The third gear from the right has an optical metamaterial that reacts to laser light and makes the gear move. All gears are made directly on a chip, allowing for precise control over their size and function.
While the potential applications of these micromotors are vast, there are still several challenges to overcome before they can be used in medical settings. According to Dr. Wang, further research is needed to develop more complex machines that can perform specific tasks within the human body. "We need to develop new materials and techniques that will allow us to build more sophisticated devices," he said.
The researchers at the University of Gothenburg are already working on developing more advanced micromotors using laser-powered gears. They plan to continue their research in this area, with a focus on creating machines that can interact with cells in new and innovative ways.
In conclusion, the development of tiny micromotors smaller than human hair using laser-powered gears is a significant breakthrough that has the potential to transform medicine. As researchers continue to work on developing more advanced devices, we may see the emergence of revolutionary medical tools that can operate at the cellular level.
