Professor Yong-Sang Kim's research lab specializes in the development of miniaturized, integrated microsystems for biomedical and environmental sensing applications. The lab focuses on microfluidic devices, lab-on-a-chip systems, and advanced electronic sensors, particularly for point-of-care diagnostics and real-time detection of biomolecules and volatile organic compounds. Key research directions include microfabrication techniques such as nanoimprinting and inkjet printing, functional nanomaterials for sensing (e.g., graphene oxide, TiO₂, Pd/TiO₂), and the integration of electronic and fluidic components for portable, low-cost analytical platforms. The lab also explores novel driving schemes for micro-LED displays and the optimization of thin-film transistors for next-generation flexible and transparent electronics.

A fully integrated microchip for performing cell lysis, polymerase chain reaction (PCR) and quantitative analysis of DNA amplicons in a single step is described herein. The chip was built on glass substrate using an indium-tin-oxide (ITO) microheater and PDMS engraved microchannels, which integrated an electrochemical cell lysis zone, a continuous flow PCR module and capillary electrophoresis amperometric detection (CE-AD) system. The total length of the microchannel was 4625 mm for performing 2
Most of the reported field effect transistors (FETs) fall short of a general method to uniquely specify and detect a target analyte. For this reason, we propose a pentacene-based FET with a graphene oxide support system (GOSS), composed of functionalized graphene oxide (GO) ink. The GOSS with a specific moiety group to capture the biomaterial of interest was inkjet printed on the pentacene FET. It provided modular receptor sites on the surface of pentacene, without alteration of the device. To e
Toluene gas was successfully measured at room temperature using a device microfabricated by a nanoimprinting method. A highly uniform nanoporous thin film was produced with a dense array of titania (TiO(2)) pores with a diameter of 70 ≈ 80 nm using this method. This thin film had a Pd/TiO(2) nanoporous/SiO(2)/Si MIS layered structure with Pd-TiO(2) as the catalytic sensing layer. The nanoimprinting method was useful in expanding the TiO(2) surface area by about 30%, as confirmed using AFM and SE
