About

Chien Chetn Cheah is a pioneering researcher in the field of micro-robotics and optical manipulation, with a primary focus on the precise handling of biological cells. His most notable contribution is the development of a novel micro-manipulation technique that uses optical tweezers to "cage" and transport individual cells without direct contact. By forming a protective cage of optically trapped micro-particles around a target cell and then employing robotic stage control, Cheah’s method enables gentle, non-invasive relocation of cells—a critical advancement for single-cell analysis and tissue engineering. Though his seminal 2020 paper has garnered 2 citations to date, its conceptual impact is significant, laying groundwork for safer cell handling in biomedical applications. Cheah’s work bridges robotics and biophysics, offering a scalable solution for automated cell sorting and assembly. His approach stands out for its elegance in combining optical trapping with robotic precision, potentially reducing cell damage during manipulation. As a researcher, Cheah continues to explore the intersection of micro-robotics and cellular biology, aiming to refine techniques that could revolutionize lab-on-a-chip devices and regenerative medicine.
