About

Xu Zheng is a researcher whose work sits at the cutting edge of micro-robotics and nanofluidics, with a particular focus on the design and mechanics of self-propelled micro-motors. His most recognized contribution comes through his 2017 study on the spherical Platinum-Silicon Dioxide (Pt–SiO2) Janus micro-motor, which has accumulated 62 citations and stands as a foundational reference in the field. This work investigates how the structural asymmetry between the two distinct hemispheres of a Janus particle can be harnessed to generate autonomous propulsion — a phenomenon with transformative implications across multiple domains. Zheng's research illuminates promising applications in environmental remediation, particularly water purification, as well as targeted drug delivery within micro and nanofluidic systems and the development of next-generation micro-robotic platforms. By providing a rigorous mechanistic understanding of self-propulsion at the microscale, Zheng has helped lay the theoretical and experimental groundwork for practical autonomous micro-devices. His contributions speak to a broader vision of engineering intelligent, self-driven systems capable of operating in complex biological and environmental settings, making his work highly relevant to researchers in soft robotics, biomedical engineering, and nanotechnology.
