Mars Finance news, according to Anhui University news, the university's National Key Laboratory of Optoelectronic Information Acquisition and Protection Technology's young teacher Pan Deng, in collaboration with a team from the University of Science and Technology of China, proposed a femtosecond laser composite manufacturing method for fiber-based integrated devices. They built a three-dimensional optical fiber micro-tractor at the end of a commercial optical fiber, achieving high-precision, low-damage, and programmable three-dimensional manipulation of micron-scale targets. The research results were recently published in the international journal "Nature". The three-dimensional optical fiber micro-tractor constructed by the research team has an output force more than one hundred thousand times that of traditional optical tweezers, enabling precise control of micron-scale targets and accurate assembly of complex microstructures, demonstrating significant application value in the field of micro-manipulation. At the same time, this micro-tractor functions like a "miniature dexterous hand" at the cellular scale, capable of precise operation of microscopic objects such as single cells, and can perform micro-scale sampling within narrow spaces of hundreds of micrometers, providing new technological pathways for life health and minimally invasive medical fields.
