- Master's Student Kim Min-seon Publishes Paper in <Sensors and Actuators B: Chemical>

狠狠撸 (President Bae Sang-hoon) announced that Kim Min-seon, a master's student in the Department of Industry 4.0 Convergence Bionics Engineering, has published a paper in the top-tier international journal *Sensors and Actuators B: Chemical* (IF 8.0) in the field of instrumentation.

Kim Min-seon, a master鈥檚 student, published a paper titled 鈥楴onelectric syringe pump capable of programmable sequential reagent injection for automated microfluidic device operation鈥� (supervised by Professor Shin Jung-ho) in International academic journal in February. The paper discusses the development of a syringe pump for microfluidic applications.

This international journal ranks in the top 0.7% of the Journal Citation Reports (JCR) and is the leading journal (ranked 1st) among 76 papers in the field of instruments & instrumentation. In this paper, Kim Min-seon, a master's student, developed a nonelectric syringe pump capable of sequentially injecting multiple solutions into a microfluidic device and presented the research results utilizing this innovation.

Microfluidic devices, which are used for the analysis and testing of various fluids, typically require large, heavy, and electrically powered syringe pumps to operate. A syringe pump is a device that supplies fluids at a constant volume and speed, and in most cases where multiple solutions are analyzed, a separate syringe pump for each solution is required to inject them sequentially.

The newly developed syringe pump, named "SMART pump" (Sequence Modifiable, Automated, and Runtime-Tunable pump), utilizes a modular sector gear design, where a part of the gear is selectively covered by teeth to precisely control the pumping timing, allowing multiple solutions to be sequentially injected with a single nonelectric pump.

Kim Min-seon, a master's student, and Professor Shin Jung-ho's research team also demonstrated the use of this syringe pump in a microfluidic-based immunoassay, successfully detecting low concentrations (100 CFU/mL) of Escherichia coli.

Professor Shin Jung-ho stated, "The results of this research are expected to be widely applicable in fields that require precise fluid control, such as Lab-on-a-chip-based smart healthcare technology, point-of-care diagnostics, and Organ-on-a-chip technologies."

Meanwhile, Professor Shin Jung-ho's research team conducted this study with the support of the Mid-career Researcher Support Program (RS-2023-00208049) from the National Research Foundation of Korea. Master's student Kim Min-seon is conducting her research with the support of the BK21 program (New Senior Customized Smart Healthcare Project, led by Professor Lee Byeong-il). <Pukyong Today>
