Vertically Aligned Patterned Peptide Nano Wires for Cellular Studies

Taskin M.B., Technical University of Denmark, DK

Over the years, scientific studies have shown that one crucial point when designing biological platforms is the strict environmental conditions required for cell and tissue culturing, such as pH, temperature, medium content and other parameters [...]

CarouCELL – a novel compact submerged perfusion bioreactor for drug screening and tissue engineering

Foss M., Le D.Q.S., Aarhus University, DK

Development of traditional methods of cell growth and manipulation on 2-dimensional (2D) surfaces, have been shown to be far from optimal for new challenges of tissue engineering and drug screening. This has lead to the [...]

All polymer, injection molded nanoslits, fabricated through two-level UV-LIGA processes

Østergaard P.F., Mateucci M., Marie R., Kristensen A., Taboryski R., Technical University of Denmark, DK

Micro- and nanofluidic systems fabricated in silicon and glass substrates are expensive and have long production cycles. To minimize the time used by researchers to fabricate their systems, rather than using them, medium to high [...]

A Pressure Controlled Pinched Flow Fractionation Device for Continuous Particle Separation

Trosborg J., Christiansen T.L., Technical University of Denmark, DK

A demonstration of a pinched flow fractionation device that enables pressure controlled tuning of the separation range of particles. This makes the device ready for easy and cheap mass-production, maintaining great flexibility, and rendering the [...]

All-In-Polymer Injection Molded Device for Single Cell Capture Using Multilevel Silicon Master Fabrication

Tanzi S., Larsen S.T., Matteucci M., Taboryski R., Technical University of Denmark, DTU Nanotech, DK

This work demonstrates a novel all-in-polymer device for single cell capture applicable for biological recordings. The chip is injection molded and comprises a “cornered” (non planar) aperture. Zanetti et al. have reported that mammalian cells [...]

Conductive Polymer Microelectrodes for on-chip measurement of transmitter release from living cells

Tylsgaard Larsen S., Matteucci M., Taboryski R., Technical University of Denmark, DK

In this work we present an all-polymer chip for measuring exocytotic release from neuronal cells using electrochemical sensing at a conductive polymer microelectrode. This chip combines several novel aspects, such as the use of conductive [...]

Reversible and irreversible temperature-induced changes in exchange-biased planar Hall effect bridge (PHEB) magnetic field sensors

Rizzi G., Lundtoft N.C., Østerberg F.W., Hansen M.F., Technical University of Denmark, DK

We generally investigate the use of exchange-biased planar Hall effect bridge (PHEB) magnetic field sensors for biodetection, where the sensors detect the binding and unbinding of magnetic beads to the sensor surface by biomolecular interactions. [...]

Injection molded superhydrophobic surfaces

Søgaard E., Smistrup K., Taboryski R., Technical University of Denmark, DK

The Lotus effect is used as inspiration for the fabrication of injection molded (IM) hierarchical polymer surfaces with self-cleaning properties. IM is a widespread method for the fabrication of plastic items. Surface functionalization is traditionally [...]

Evaluation of stability for monolayer injection molding tools coating

Cech J., Taboryski R., DTU, DK

We tested and characterized molecular coating of Aluminium and Nickel prototype molds and mold inserts for polymer replication via injection molding (IM). X-Ray photoelectron spectroscopy (XPS) data, sessile drop contact angles with multiple fluids, surface [...]

Titanium Tungsten Coatings for Bioelectrochemical Applications

Wierzbicki R., Amato L., Lopacinska J., Heiskanen A., Emneus J., Boggild P., Molhave K., DTU Nanotech, DK

Our research interest is the combination of carbon nanotube electrochemistry with nanostructured substrates capable of cell scaffolding. Therefore, an adhesion / electric connection coating with good biocompatibility, PECVD compatibility and electrochemical stability needs to be [...]
