A tunable, microfluidic filter for clog‑free concentration and separation of complex algal cells
Mossige, Endre Joachim; Edvardsen, Bente; Jensen, Atle; Mielnik, Michal Marek (Journal article; Peer reviewed, 2019)An inherent problem with microfluidic filters is the tendency to clog, especially when applied to cells due to their geometrical complexity, deformability, and tendency to adhere to surfaces. In this work, we handle live ... -
Biocompatible bonding of a rigid off-stoichiometry thiol-ene-epoxy polymer microfluidic cartridge to a biofunctionalized silicon biosensor
Sønstevold, Linda; Yadav, Mukesh; Arnfinnsdottir, Nina Bjørk; Herbjørnrød, Aina Kristin; Jensen, Geir Uri; Aksnes, Astrid; Mielnik, Michal Marek (Peer reviewed; Journal article, 2022)Attachment of biorecognition molecules prior to microfluidic packaging is advantageous for many silicon biosensor-based lab-on-a-chip (LOC) devices. This necessitates biocompatible bonding of the microfluidic cartridge, ... -
Curved passive mixing structures: a robust design to obtain efficient mixing and mass transfer in microfluidic channels
Øvreeide, Ingrid Haga; Zoellner, Andreas; Mielnik, Michal Marek; Stokke, Bjørn Torger (Peer reviewed; Journal article, 2021)Analyte mixing and delivery to a functionalized sensor surface are important to realize several advantages associated with biosensors integrated with microfluidic channels. Here, we present a comparison between a herringbone ... -
High aspect ratio deep RIE for novel 3D radiation sensors in high energy physics applications
Kok, Angela; Hansen, Thor-Erik; Hansen, Trond Andreas; Jensen, Geir Uri; Lietaer, Nicolas; Mielnik, Michal Marek; Storås, Preben (Journal article; Peer reviewed, 2009)3D detectors with electrodes penetrating through the entire silicon substrate have many advantages over conventional planar silicon technology, for example, high radiation tolerance. High aspect ratio through-wafer holes ... -

Furuberg, Liv; Mielnik, Michal Marek; Johansen, Ib-Rune; Borch, Morten; Stenstad, Per Martin (Lecture, 2009) -
Next lot of 3-D detectors at SINTEF
Hansen, Thor-Erik; Kok, Angela; Hansen, Trond Andreas; Lietaer, Nicolas; Mielnik, Michal Marek; storås, Preben; Jensen, Geir Uri (Lecture, 2009) -
Separation and Concentration without Clogging Using a High-Throughput Tunable Filter
Mossige, Endre Joachim; Jensen, Atle; Mielnik, Michal Marek (Journal article; Peer reviewed, 2018)We present a detailed experimental study of a hydrodynamic filtration microchip and show how chip performance can be tuned and clogging avoided by adjusting the flow rates. We demonstrate concentration and separation of ... -
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 ... -
Technologies enabling 3D stacking of MEMS
Taklo, Maaike Margrete Visser; Mielnik, Michal Marek; Schjølberg-Henriksen, Kari; Storås, Preben; Tofteberg, Hannah Rosquist; Lietaer, Nicolas; Johannessen, Rolf (Chapter, 2010) -
Teflon-carbon black as new material for the hydrophobic patterning of polymer labs-on-a-chip
Mielnik, Michal Marek (Chapter, 2009)We provide a new method for the selective surface patterning of microfluidic chips with hydrophobic fluoropolymers which is demonstrated by the fabrication of hydrophobic valves. It enables efficient optical quality control ...
