About

Heng Xie is a pioneering researcher in the field of biomicromanipulation, with a focus on developing noninvasive, high-precision techniques for handling living cells. His key research areas include optical tweezers, microtool-assisted cell transport, and 3D-printed microdevices for biological applications. Xie’s most cited work, "Automated Indirect Transportation of Biological Cells with Optical Tweezers and a 3D Printed Microtool" (2019, 18 citations), addresses a critical limitation of conventional optical tweezers: the risk of photodamage from direct laser exposure. By integrating a custom 3D-printed microtool with automated optical trapping, he enabled indirect cell manipulation—allowing cells to be moved without direct laser contact, preserving their viability and physiological integrity. This innovation bridges the gap between precision and safety, offering a scalable solution for tasks like single-cell analysis and tissue engineering. Xie’s contributions are particularly notable for their interdisciplinary approach, combining robotics, optics, and additive manufacturing to solve real-world biological challenges. His work has been recognized for its potential to advance lab-on-a-chip technologies and automated cell surgery, making him a rising leader in the intersection of microengineering and biomedicine.
