  • Noise spectroscopy of gas sensors
  • 2008
  • Ingår i: IEEE Sensors Journal. - 1530-437X .- 1558-1748. ; 8:5-6, s. 786-790
  • Tidskriftsartikel (refereegranskat)abstract
    • We study current-voltages and low-frequency noise characteristics of the metal-porous silicon-silicon single crystal-metal structure with 50% and 73% porosity of porous silicon. The study is performed in dry air and in a mix of dry air with carbon monoxide of different concentrations. The Hooge noise parameter alpha(H) and the parameter gamma in the frequency dependence of the noise voltage spectral density S-U (f) were determined from experimental data. High sensitivity of spectral dependence of noise to gas concentration allows offering powerful method for determination of gas concentration in the air or environment.

  • Photonic sensing of food allergy : integration and miniaturization
  • 2012
  • Ingår i: Smart Systems Integration.
  • Konferensbidrag (refereegranskat)abstract
    • Food allergies can provoke severe clinical reactions. Within the FP7 project POSITIVE a Lab-on-a-Chip platform for label-free quantitative allergen testing is under development. The system integrates fluidic handling, optical interrogation and a porous Silicon based bio sensor cartridge. Optical and fluidic concepts have been derived and partially tested with positive results on lab bench level. Further effort has to be spent on higher system integration and miniaturization of the components as well as signal processing and data evaluation. Model tests based on the immobilization of allergens and molecular recognition by specific antibodies have been established proofing the pre-treated porous Silicon membranes bio assay suitability.
