Yoon-Kyoung Cho's Biography

Yoon-Kyoung Cho, Professor, Biomedical Engineering, Ulsan National Institute of Science & Technology; Group leader, IBS; FRSC, Fellow of Royal Society of Chemistry

Yoon-Kyoung Cho is a full professor of Biomedical Engineering at UNIST and a group leader in the Center for Soft and Living Matter at the Institute for Basic Science (IBS), Republic of Korea. She is a member of the National Academy of Engineering of Korea (NAEK) and a Fellow of Royal Society of Chemistry (FRSC). She serves as a director at the Chemical and Biological Microsystems Society (CBMS) and an associate editor for Lab on a chip. She received her Ph.D. in Materials Science and Engineering from the University of Illinois at Urbana-Champaign (UIUC) in 1999, having obtained her M.S. and B.S. in Chemical Engineering from POSTECH in 1994 and 1992, respectively. She worked as a senior researcher (1999–2008) at Samsung Advanced Institute of Technology (SAIT), where she helped create biomedical in vitro diagnostic instruments. Her research spans a broad spectrum from fundamental scientific exploration to translational efforts, focusing primarily on microfluidics and nanomedicine. Her current research topics include a lab-on-a-disc for the detection of rare cells and biomarkers, quantitative analysis of single cells, and system analysis of cellular communication. She published over 135 journal papers and over 205 issued patents, many of which helped Samsung Electronics and two start-ups (Clinomics and LabSpinner) build commercial products. Discover more at

The lab-on-a-disc systems to isolate and detect liquid biopsy markers such as circulating tumor cells (CTCs) and cell-free DNA(cfDNA) or Extracellular vesicles (EVs) are developed and tested with clinical samples such as whole blood or urine from cancer patients. First, we will introduce the fluid-assisted separation technology (FAST), which enables ultrafast, uniform, clog-free, and highly efficient isolation of CTCs from whole blood with pressure drop much less than in conventional filtration. In addition, we demonstrate a fully automated cfDNA enrichment device integrating the plasma separation, sample lysis, DNA binding and elution on a single device. We used the lab-on-a-disc to isolate cfDNA from patients with non-small cell lung cancer and successfully detected epidermal growth factor receptor gene mutations (L858R, T790M) during targeted drug therapy. Next, we will present a rapid, label-free, and highly sensitive method for EVs isolation and quantification using a lab-on-a-disc integrated with nanofilters (Exodisc). Urinary EVs from prostate cancer patients could be automatically enriched within 30 min using a tabletop-sized centrifugal microfluidic system followed by molecular analysis or on-chip ELISA. As a proof of concept study, we analyzed androgen receptor splice variant 7 (AR-V7) which is associated with castration-resistant prostate cancer (CRPC) and resistance to anti-androgen therapy in the RNA isolated from the urine-derived extracellular vesicles (EVs) without the need for blood withdrawal. Further, the device also facilitates temporal monitoring of tumor progression within live mouse xenograft models over a period of 13 weeks whilst using minimal volume of weekly collected blood samples. Taken together, Exodisc is a powerful tool to provide a rapid, sensitive, and point-of-care-type method for extracting intact EVs from urine or small volumes of blood samples for disease diagnosis and monitoring. We believe that this revolutionary method can contribute to accelerate the acceptance of liquid biopsy-based cancer diagnostics as a standard practice in clinical settings.
