    Sammanfattning : Dispersed non-spherical particles are the fundamental constituent of many complex fluids. Such fluids are studied both for their industrial and scientific importance, and for their peculiar functional properties (mechanical, optical, thermal, fluidic). LÄS MER

  5. 4. Microcontact Printing for Protein Microarray Applications

    Författare :Ye Zhou; Per Claesson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis introduces the microcontact printing (μCP) method to pattern and tailor the desired substrates for protein microarray applications. The ink molecules used to create the patterns, hydrophobic barriers, are tetraalkyl ammonium salt, polycationic polymers and oligo(ethylene glycol)-terminated self-assembled monolayers. LÄS MER
