    Sammanfattning : The combination of laminar flows in microfabricated channels and acoustic forces induced in ultrasonic standing wave fields offers new possibilities for advanced particle and cell manipulation in lab-on-a-chip applications as well as in relatively high throughput applications. Acoustic particle manipulation systems can be used e.g. LÄS MER

  4. 3. Development of Protein Microarray Chip Technology: An Outlook towards Proteomics and Diagnostics

    Författare :Anton Ressine; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; Teknik; Technological sciences; Naturvetenskap; Natural science; Diagnostik; Diagnostics; Medicin människa och djur ; Medicine human and vertebrates ; Biomedicinska vetenskaper; Biomedical sciences; water repellency; superhydrophobicity; proteolitic digestion; MALDI-TOF MS; bioassay; porous silicon; biomarker; diagnostics; protein microarrays; proteomics;

    Sammanfattning : One attractive method for monitoring biomolecular interactions in a highly parallel fashion is the use of microarrays. Microarrays can be applied for screening proteins which makes it an attractive tool in clinical diagnostics, drug discovery studies and basic protein research; even though many methodological challenges and ones relating to the quality control of microarrays still need to be solved.
