1. 11. Design of a rapid point-of-care immunoassay : Based on a single-step non-competitive immunoassay with magnetic permeability detection

   Författare :Filiz Ibraimi; Tillämpad biokemi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superparamagnetic nanoparticles; magnetic permeability; two-site immunoassay; point-of-care; diagnostic test; biomarkers;

   Sammanfattning : This thesis describes the development of a one-step, specific, cost-effective and rapid in vitro point-of-care immunoassay test based on a unique magnetic immunoassay principle. The principle in question is based on a non-competitive heterogeneous immunoassay in a one-step analysis, relying on magnetic permeability detection. LÄS MER

3. 12. Differential Magnetic Biosensor using HTS SQUID Gradiometer

   Författare :Sobhan Sepehri; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; magnetic bioassay; diagnostics; RCA; microfluidics; magnetic nanoparticle; point-of-care; rolling circle amplification; differential ac susceptibility; biosensor;

   Sammanfattning : A fundamental tool for containing an epidemic outbreak and mitigating its effects is early diagnostics. Currently, most of the diagnostic tests are performed by trained staff in centralized labs, which are expensive and time-consuming to establish and operate. Lack of access to such facilities could have devastating effects. LÄS MER

4. 13. Microactuators for Powerful Pumps

   Författare :Roger Bodén; Klas Hjort; Jan-Åke Schweitz; Johan Nilsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; µTAS; chromatography; high pressure; lab-on-a-chip; microactuator; microdispenser; micropump; on-chip; paraffin; PCM; point-of-care; Engineering physics; Teknisk fysik;

   Sammanfattning : When paraffin wax melts it exhibits a large, relatively incompressible volume expansion. This can be used in microactuators for strong and large displacements, a rare combination among actuators. Furthermore, paraffin is inexpensive, inert and environmentally friendly, as well as easily processed and actuated. LÄS MER

5. 14. Digital Electrical DNA Sensing

   Författare :Maoxiang Guo; Wouter van der Wijngaart; Fredrik Westerlund; KTH; []
   Nyckelord :DNA detection; thiol-ene-epoxy; rolling circle amplification; digital measurement; DNA stretching; microwell-array; gold nanowires; electrical measurement; specificity; limit of detection; liquid storage; disease diagnosis; lab-on-a-chip; point-of-care.;

   Sammanfattning : Molecule detection is a workhorse in life sciences and medicine, for example in cancer diagnosis and virus and bacterial detection. DNA analysis can provide vital information about the state of a host organism and its medical and health condition. LÄS MER
