Optical Sorting: Revolutionizing Cell Sorting in Biomedicine

Yuanyuan Liu’s Light Workbench Accelerates Antibody Discovery

In the evolving landscape of biomedical research, efficient cell sorting is a pivotal step for advancements in antibody drug development. Optical Sorting, developed by Yuanyuan Liu and team, replaces traditional manual methods with optoelectronic dielectrophoresis—a technology that precisely manipulates individual cells using light and electrical fields. This innovation streamlines the sorting process, reducing both time and risk of sample damage, and is poised to transform laboratory workflows worldwide.

At the heart of this system lies the Light Workbench, an AI-powered nanobiochip platform capable of rapidly separating, analyzing, culturing, and exporting tens of thousands of single cells in parallel. Unlike conventional hybridoma technology, which is often hampered by lengthy cycles and limited analytical capabilities, the Light Workbench completes positive plasma cell screening within a single day. This leap in efficiency is crucial for accelerating antibody discovery and reducing development costs.

The design integrates advanced technologies such as optical-induced dielectrophoresis, microfluidics, micro-nano fabrication, and automated imaging. Cells are loaded into a microfluidic chip, where they are manipulated and sorted based on their unique properties. Real-time imaging and AI-driven analysis ensure precise identification and classification, while automation enables seamless collection and processing of sorted cells for further research.

Measuring 60cm by 80cm by 170cm, the Optical Sorting system is engineered for laboratory environments, offering a compact yet powerful solution for high-throughput cell analysis. Its development, spanning from December 2020 to August 2023 in Beijing, was driven by rigorous research and experimentation, resulting in new insights and methodologies that promise to shape the future of biomedical science.

Recognized with the prestigious Golden A' Design Award in 2025, Optical Sorting stands as a testament to innovation at the intersection of science, technology, and design. By enabling faster, more reliable cell sorting, this system empowers researchers to push the boundaries of antibody discovery and therapeutic development, marking a significant milestone in scientific instrumentation.

As the demand for efficient biomedical tools continues to grow, Optical Sorting’s unique combination of precision, speed, and automation sets a new standard for research laboratories, inspiring further advancements in the field of life sciences.
