    • Application of Polymethylpentene, an Oxygen Permeable Thermoplastic, for Long-Term on-a-Chip Cell Culture and Organ-on-a-Chip Devices 

      Sønstevold, Linda; Czerkies, Maciej; Escobedo-Cousin, Enrique; Blonski, Slawomir; Vereshchagina, Elizaveta (Peer reviewed; Journal article, 2023)
      The applicability of a gas-permeable, thermoplastic material polymethylpentene (PMP) was investigated, experimentally and analytically, for organ-on-a-chip (OoC) and long-term on-a-chip cell cultivation applications. Using ...

    • 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) ...

    • Metal Films for MEMS Pressure Sensors: Comparison of Al, Ti, Al-Ti Alloy and Al/Ti Film Stacks 

      Vereshchagina, Elizaveta; Poppe, Erik Utne; Schjølberg-Henriksen, Kari; Wöhrmann, Markus; Moe, Sigurd T. (Chapter, 2018)
      Thermo-mechanical stability of metal structures is one of the key factors affecting accuracy of micro-electromechanical (MEMS) piezoresistive pressure sensors. In this work, we present the measurement results of stress and ...

    • Microfluidic devices for photo-and spectroelectrochemical applications 

      Bogdanowicz, Robert; Jönsson-Niedziółka, Martin; Vereshchagina, Elizaveta; Dettlaff, Anna; Boonkaew, Suchanat; Pierpaoli, Mattia; Wittendorp, Paul; Jain, Shruti; Tyholdt, Frode; Thomas, Jacob; Wojcik, Pawel (Peer reviewed; Journal article, 2022)
      The review presents recent developments in electrochemical devices for photo- and spectroelectrochemical investigations, with the emphasis on miniaturization (i.e., nanointerdigitated complementary metal-oxide-semiconductor ...

    • Simultaneous improvement of surface finish and bonding of centrifugal microfluidic devices in cyclo-olefin polymers 

      Vereshchagina, Elizaveta; Andreassen, Erik; Batalden, Jørn; Plassen, Martin; Mielnik, Michal Marek (Chapter, 2018)
      Two key issues in the manufacturing of microfluidic devices are to obtain low surface roughness, i.e. in the range of nanometers (to facilitate optical detection and controlled flow through microfluidic networks), and to ...

    • 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 ...
