  2. 1. Autonomous Lab-on-a-chip: solutions and fast prototyping tools

    Author : German Comina Bellido; Daniel Filippini; Edwin Jager; Anke Suska; Niels B. Larsen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Lab-on-a-chip; bio-chemical sensing; sensor fabrication; biosensing cell phone; 3D printed fluidics; 3D printed optics.;

    Abstract : In this thesis, solutions for the development of autonomous Lab-on-a-chip (LOC), and 3D printing for fast prototyping of LOC devices are investigated. Lab-on-a-chip devices integrate analytical systems and conditioning processes in a compact package. READ MORE

  4. 2. A Standard Mobile Phone as a Chemical Sensor

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

    Abstract : 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. READ MORE

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gold nanoparticle; polypeptide; helix-loop-helix; four-helix bundle; self-assembly; folding; Chemistry; Kemi;

    Abstract : Self-assembly has emerged as a promising technique for fabrication of novel hybrid materials and nanostructures. The work presented in this thesis has been focused on developing nanoscale materials based on synthetic de novo designed polypeptides. READ MORE

  6. 4. Optical Sensing With an Ordinary Mobile Phone

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

    Abstract : 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.

  7. 5. Centrifugal microfluidics-based point of care diagnostics at resource limited settings

    Author : Ahmad Saleem Akhtar; Aman Russom; Ines Fernandes Pinto; Nicole Pamme; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microfluidics; centrifugal microfluidics; point-of-care; low-cost; diagnostics; agarose beads; immunoassays; colorimetry; fluorescence; cytokines; nucleic acid amplification; isothermal amplification; COVID-19; portable; smartphone; resource limited settings.; Biotechnology; Bioteknologi;

    Abstract : Advancements in medical diagnostics have allowed us to understand the underlying mechanism and treat the root cause for many diseases which had been causing morbidity and mortality up until this point in human history. Furthermore, many of the standard diagnostic procedures have now been transformed to provide answers at or near the point-of-care. READ MORE
