Hanbat National University announced on December 30 that a paper titled "Plasmonic Filter Paper for Microplastic Detection: SERS Enhancement, Size Dependence, and Quantitative Limitations," with Minjung Kim, a fourth-year student in the Department of Materials Science and Engineering, as the lead author, was recently published in "RSC Advances," an international journal issued by the Royal Society of Chemistry in the United Kingdom.

Kim conducted research by utilizing filter paper coated with gold nanostructures as a surface-enhanced Raman spectroscopy (SERS) sensor, confirming that the effectiveness of SERS can vary significantly depending on the size of the microplastics.
Furthermore, she clearly identified that even if the technique demonstrates effectiveness when the size of microplastics is reduced to the nanometer scale, there are limitations in the quantitative analysis process.
This study was initiated based on the observation that while surface-enhanced Raman spectroscopy is gaining attention as a promising technology for measuring microplastics, there has not been sufficient discussion about the limitations that may arise when this technique is applied to microplastic measurement.
Professor Wee Jeongseop, Kim's academic advisor in the Department of Materials Science and Engineering, stated, "This research is significant as it provides important insights into the detection and analysis of microplastics."
