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 hysteresis for the following metals deposited in the same sputtering equipmen...

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 achieve robust bonding. Here we report that a chemical polishing step, used for...

I det nystartete prosjektet EXIT (EXosomes Isolation Tool) skal SINTEF, som en del av en flerfaglig gruppe, utvikle et miniatyrisert analyseverktøy for å undersøke eksosomer i prøver fra pasienter med Alzheimers sykdom. Eksosomer «bærer» ulike molekyler som protein...

A new rapid prototyping method is reported. It is based on injection molding with inexpensive mold inserts, 3D-printed in durable polymer-based materials. The method allows for manufacturing of microfluidics in common thermoplastics materials at a lower cost and with shorter lead-times compared to i...

Allergies to antibiotics are the commonest form of medication allergies and, in the worst cases, can result in anaphylaxis and death. SINTEF is participating in the development of a new allergy test that will make it easier to provide patients with safe and correct treatments....

Mange får bredspektret antibiotika fordi de tror de er allergiske mot penicillin. Norske forskere utvikler nå en allergitest som avslører hvem som er allergiske, og graden av allergi. Det vil gi bedre behandling mot infeksjoner- og motvirke resistens....

Paper microfluidics play an increasing role in biomedical research. This interest is attributed to the technological simplicity, the considerably lower costs compared to other fabrication approaches, as well as good compatibility with many bioanalytical procedures. A paper-based analytical device ca...

Cells communicate by means of "messengers" known as extracellular vesicles, i.e. small (30‐1000 nm) cell derived vesicles released from almost all eukaryotic cells into their extracellular environment and containing a variety of proteins and RNAs [1]. It has been foreseen that the next gen...
