EC-SERS detection of thiabendazole in apple juice using activated screen-printed electrodes
Moldovan, Rebeca; Milenko, Karolina Barbara; Vereshchagina, Elizaveta; Iacob, Bogdan-Cezar; Schneider, Kenneth; Farcău, Cosmin; Bodoki, Ede (Peer reviewed; Journal article, 2022)Thiabendazole (TBZ), a benzimidazole fungicide used for post-harvest treatment, may be a trace contaminant of food matrices. In this work, we report the first EC-SERS (electrochemical-surface enhanced Raman spectroscopy) ... -
Micro-lensed negative-curvature fibre probe for raman spectroscopy
Milenko, Karolina Barbara; Yerolatsitis, Stephanos; Aksnes, Astrid; Hjelme, Dag Roar; Stone, James M. (Peer reviewed; Journal article, 2021)We developed a novel miniature micro-lensed fibre probe for Raman spectroscopy. The fibre probe consists of a single negative-curvature fibre (NCF) and a spliced, cleaved, micro-lensed fibre cap. Using a single NCF, we ... -
Toward microfluidic SERS and EC-SERS applications via tunable gold films over nanospheres
Falamas, Alexandra; Cuibus, Denisa; Tosa, Nicoleta; Brezestean, Ioana; Muntean, Cristina M.; Milenko, Karolina Barbara; Vereshchagina, Elizaveta; Moldovan, Rebeca; Bodoki, Ede; Farcau, Cosmin (Peer reviewed; Journal article, 2023)Many promising applications of surface-enhanced Raman scattering (SERS), such as microfluidic SERS and electrochemical (EC)-SERS, require immersion of plasmonic nanostructured films in aqueous media. Correlational ... -
UV-Nanoimprint and Deep Reactive Ion Etching of High Efficiency Silicon Metalenses: High Throughput at Low Cost with Excellent Resolution and Repeatability
Dirdal, Christopher Andrew; Milenko, Karolina Barbara; Summanwar, Anand; Dullo, Firehun Tsige; Thrane, Paul Conrad Vaagen; Rasoga, Oana; Avram, Andrei M.; Dinescu, Adrian; Baracu, Angela M. (Peer reviewed; Journal article, 2023)As metasurfaces begin to find industrial applications there is a need to develop scalable and cost-effective fabrication techniques which offer sub-100 nm resolution while providing high throughput and large area patterning. ... -
UV-Nanoimprint Lithography for Predefined SERS Nanopatterns Which Are Reproducible at Low Cost and High Throughput
Milenko, Karolina Barbara; Dullo, Firehun Tsige; Thrane, Paul Conrad Vaagen; Skokic, Zeljko; Dirdal, Christopher Andrew (Peer reviewed; Journal article, 2023)A controlled and reliable nanostructured metallic substrate is a prerequisite for developing effective surface-enhanced Raman scattering (SERS) spectroscopy techniques. In this study, we present a novel SERS platform ...
