The research team of Professor Jihoon Lee (Dept. of Electronic Engineering), in collaboration with Rutuja Mandavkar (the first author), a doctoral researcher, successfully developed  an ultra-sensitive hydrogen peroxide (H2O2) detection sensor using a 3D porous Au/CuO/Pt hybrid framework. In this research, the team proposed a 3D porous Au/CuO/Pt hybrid sensor platform to overcome the shortcomings of non-enzymatic hydrogen peroxide detection sensors and succeeded in developing the Au/CuO/Pt hybrid sensor and a 3-electrode on-chip biosensor kit. 

The research team included Rutuja Mandavkar (doctoral researcher, first author), Shusen Lin (integrated master's and Ph.D. program), Md Ahasan Habib (doctoral researcher), Shalmali Burse (doctoral researcher), Mehedi Hasan Joni (integrated master's and Ph.D. program), Sundar Kunwar (doctoral researcher), Jae-Hun Jeong (research professor, corresponding author), Jihoon Lee (professor, corresponding author), Adel Najar (United Arab Emirates University), and S. Assa Aravindh (University of Oulu, Finland, corresponding author) in an international collaborative research effort. Rutuja Mandavkar, the first author, entered the electronic engineering Ph.D. program at the university in 2020 and has since published numerous papers as a first-author or co-author. She is about to graduate.  The researcher, Rutuja is happy that her research on hydrogen oxide detection sensors has been published in an excellent journal, and she expresses her aspiration to continue her research at a prestigious research institute after graduation.

This research was supported by the Brain Korea 21 Plus (BK-21) program, a key research project, and Kwangwoon University and the research findings were published in the online edition of scientific journal Sensors and Actuators B: Chemical (JCR category INSTRUMENTS & INSTRUMENTATION, ranked 1st, IF: 8.4) in the August 2023 under the title "Ultra-sensitive H2O2 sensing with 3-D porous Au/CuO/Pt hybrid framework."
