  1. 1. A Standard Mobile Phone as a Chemical Sensor

    Författare :Zafar Iqbal; Mats Eriksson; Stefan Klintström; Tomas Strömberg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis describes work to investigate the potential of using an ordinary mobile phone to perform chemical sensing by colorimetric analysis of reflected light. The wide availability and familiarity of mobile phones make them excellent devices for aiding consumers in making on site tests in their everyday lives. LÄS MER

  3. 2. Optical Sensing With an Ordinary Mobile Phone

    Författare :Zafar Iqbal; Ingemar Lundström; Robert Björklund; Mats Eriksson; Magnus Willander; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : A major portion of the world’s population (≈ 80% of the total) lives in developing countries where lab instruments such as spectrophotometers are not widely available as their purchasing as well as maintenance is normally unaffordable. On the other hand, there are now around five billion mobile phone subscriptions worldwide and the current generation of standard mobile phones has several capabilities to perform user-defined analysis.

  5. 4. 2nd and 3rd generation electrodes for biosensors and biofuel cells

    Författare :MNadeem Zafar; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER

  7. 5. Synthesis of metal oxide nanostructures, their characterization and chemical sensing applications

    Författare :Zafar Hussain Ibupoto; Magnus Willander; Bansi Malhotra; Linköpings universitet; []
    Nyckelord :Hydrothermal method; seed layer; ZnO nanorods; ZnO nanotubes; immunosensor; iron ferrite; glucose sensor; well aligned ZnO nanorods; CuO nanoleaves; CuO nanosheets; CuO bundle of nanowires;

    Sammanfattning : The existence of nanomaterials is a revolutionizing step towards the fabrication of nanodevices and it enhances the enthusiasm of the researchers for the development of new devices with improved performance relative to that of bulk material based devices. Among the nanomaterials, the metal oxide nanostructures have drawn the attention of scientific community in the development of different biochemical and biomedical nanodevices in the recent time.
