    Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial plastic materials that mimic antibodies or enzymes. Like natural antibodies or enzymes, molecularly imprinted polymers can selectively bind target molecules or can promote catalytic reactions. LÄS MER

  5. 29. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

    Författare :Tobias Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. LÄS MER

  7. 30. Towards flexible organic electronics : photoelectron spectroscopy of surfaces and interfaces

    Författare :Stina Jönsson; Ian D. Parker; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Intensive studies of conjugated molecules and polymers are carried out all over the world with the intent of obtaining cheap and efficient organic electronic devices. The most mature application at the moment is the light-emitting diode, but also photovoltaic cells and different types of transistors shows promising results. LÄS MER
