  1. 1. Novel Microfluidic Devices Based on a Thermally Responsive PDMS Composite

    Författare :Björn Samel; Göran Stemme; Jörg Kutter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; microsystem technology; micro total analysis system; lab-on-a-chip; microfluidics; composite actuator; expandable microspheres; PDMS; poly dimethylsiloxane; disposable; wafer bonding; adhesive bonding; PDMS bonding; adhesive PDMS bonding; selective PDMS bonding; microcontact printing; Electrical engineering; Elektroteknik;

    Sammanfattning : The field of micro total analysis systems (μTAS) aims at developments toward miniaturized and fully integrated lab-on-a-chip systems for applications, such as drug screening, drug delivery, cellular assays, protein analysis, genomic analysis and handheld point-of-care diagnostics. Such systems offer to dramatically reduce liquid sample and reagent quantities, increase sensitivity as well as speed of analysis and facilitate portable systems via the integration of components such as pumps, valves, mixers, separation units, reactors and detectors.

  3. 2. Carbon Nanotubes for Electronic Packaging: Growth, Novel Devices and 3D Networks

    Författare :Yifeng Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-scale modeling; electrospinning; microfin; PDMS; chemical vapor deposition CVD ; Carbon nanotube CNT ; double-walled CNT DWNT ; CNT covalent bonding; CNT transfer; thermal management; packaging;

    Sammanfattning : Carbon nanotubes (CNTs) have shown great potential of application in electronics because of their attractive physical properties, such as high surface-to-volume ratio, high electron mobility, high Young’s modulus, high thermal conductivity, low thermal expansion coefficient, etc. However, many obstacles are yet to be removed to use CNTs as building blocks in electronic systems.

  4. 3. Device Bonding and Antibody Binding: Developments for On-Chip Differentiation of Induced Pluripotent Stem Cells into Hepatocytes

    Författare :Philip Dalsbecker; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microfluidics; liver-on-a-chip; organ-on-chip; PDMS; oxygen plasma; immunofluorescence; fluorescence microscopy; hepatocytes; iPSC; induced pluripotent stem cells; differentiation; on-chip differentiation; definitive endoderm;

    Sammanfattning : Abstract This thesis describes the bonding optimization of a liver-on-a-chip microfluidic device for evaluation of cultured induced pluripotent stem cell (iPSC)-derived definitive endoderm (DE) cells during their targeted differentiation into mature hepatocytes. Furthermore, it describes the optimization of a number of antibody assays for use during said differentiation, for the purpose of studying the cellular phenotype. LÄS MER

  5. 4. Barnacle Bioadhesive Bonding Formation, Strength and Control

    Författare :Mattias Berglin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barnacle adhesive plaque; poly dimethylsiloxane ; fouling release coatings; bioadhesion; marine biofouling;

    Sammanfattning : The current technology for keeping ship hulls free of marine biofouling requires the use of toxic compounds such as copper, organic biocides and tributyl tin (TBT). The compounds that are released have been shown to have negative effects on non-target organisms, and a worldwide ban of TBT is currently being introduced. LÄS MER

    Sammanfattning : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. LÄS MER
