Pukyong National University (President Bae Sanghoon) announced on the 11th that Kim Minseon, a master's student in the Department of Convergence Bionics Engineering for the Fourth Industrial Revolution, has published a paper in a top-tier international journal in the Instruments & Instrumentation field.
Kim Minseon published the paper titled "Nonelectric syringe pump capable of programmable sequential reagent injection for automated microfluidic device operation" (supervised by Professor Shin Jungho) in this international journal in February. The paper details research on the development of a syringe pump for microfluidics.
This international journal ranks in the top 0.7% of the Journal Citation Reports (JCR) and is the number one journal among 76 publications in the Instruments & Instrumentation field. In the paper, Kim Minseon developed a nonelectric syringe pump capable of sequentially injecting multiple solutions into microfluidic devices and presented research results utilizing this technology.
Typically, operating microfluidic devices used for the analysis and inspection of various fluids requires large, heavy, and electrically powered syringe pumps. A syringe pump is a device that supplies fluids at a constant volume and speed, and most analyses involving multiple solutions require as many syringe pumps as there are solutions for sequential injection.
The newly developed syringe pump, named "SMART pump (Sequence Modifiable, Automated, and Runtime-Tunable pump)," applies a modular sector gear mechanism. It is designed to selectively cover parts of the gear with teeth, enabling precise control of pumping timing, and thus allows a single nonelectric pump to sequentially inject multiple solutions.
The research team of Kim Minseon and Professor Shin Jungho also presented results detecting trace amounts (100 CFU/mL) of Escherichia coli using a microfluidic-based immunoassay with this syringe pump.
Professor Shin Jungho stated, "These research results are expected to have broad applications in fields requiring precise fluid control, such as smart healthcare technology and point-of-care diagnostics based on lab-on-a-chip, as well as organ-on-a-chip technology."
The research team led by Professor Shin Jungho conducted this study with support from the National Research Foundation of Korea's mid-career researcher program, and Kim Minseon is currently conducting research with support from the BK21 program (New Senior Customized Smart Healthcare Project Group, led by Professor Lee Byungil).
