    Sammanfattning : Today there is growing interest in research on microfluidicsystems, e.g., for chemical analysis systems and microdosagesystems. One of the basic components in microfluidic systems ismicropumps. LÄS MER

  2. 7. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    Författare :Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. LÄS MER

  3. 8. A Fully Integrated Microneedle-based Transdermal Drug Delivery System

    Författare :Niclas Roxhed; Göran Stemme; Mark G. Allen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microneedle; Transdermal; Intradermal; Drug delivery; DRIE; MEMS; Microsystem; Medical technology; Medicinsk teknik;

    Sammanfattning : Patch-based transdermal drug delivery offers a convenient way to administer drugs without the drawbacks of standard hypodermic injections relating to issues such as patient acceptability and injection safety. However, conventional transdermal drug delivery is limited to therapeutics where the drug can diffuse across the skin barrier. LÄS MER
