Localized near-field distribution induced by plasmonic nanopost array was applied for super-resolved Raman microscopy. Results show almost 4-fold improvement in the lateral precision over conventional diffraction-limited Raman microscopy images.
The paper titled “Surface plasmon localization-based super-resolved Raman microscopy” will be published in Nano Letters, one of the top journals in nanoscience and nanotechnology (Q1 with IF 12.344).
This study was led by Drs. Hongki Lee and Kyungnam Kang  (co-first authors) of the BPEL (Supervising Professor: Donghyun Kim). Professors Kar-Ann Toh and Seung Ah Lee also participated in collaboration with K. Fujita at Osaka University of Japan.
