  1. 21. Virus-cell membrane interactions - Binding studies of Herpes Simplex Virus using surface-sensitive techniques

    Författare :Nadia Peerboom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TIRF microscopy; single particle tracking; binding kinetics; glycosaminoglycans; herpes simplex virus;

    Sammanfattning : Viruses are parasites capable of infecting all forms of life. They lack the ability to replicate by themselves and therefore hijack the replication machinery of cells to produce new viral copies, called virions. LÄS MER

  3. 22. Optical devices and methods for distributed lab-on-a-chip analyses

    Författare :Pakorn Preechaburana; Daniel Filippini; Ingemar Lundström; Readislav Potyrailo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Lab-on-a-chip (LOC) technologies entail the miniaturization of analytical systems, and the reduction of required sample and reagent volumes. LOC devices offer compact alternatives to classical instrumentation while delivering comparable performance and disposable formats. LÄS MER

  4. 23. Pitfalls in β-cell ion imaging with fluorescent indicators and their use for real-time detection of somatostatin secretion

    Författare :Mingyu Yang; Anders Tengholm; Enming Zhang; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; β-cells; cytoplasmic Ca²⁺; cytoplasmic pH; fluorescent indicators; pancreatic islets; R-GECO1; somatostatin; type 2 diabetes; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Fluorescent ion indicators have become indispensable tools in cell physiology. Dye indicators can easily be loaded into most types of cells, while genetically encoded indicators are advantageous in allowing specific cellular or subcellular targeting. LÄS MER

  5. 24. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces

    Författare :Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Layer-by-layer; multilayer; adsorption; biopolymers; Chitosan; Heparin; Mucin; Albumin; Lysozyme; β-casein; SDS; QCM-D; Ellipsometri; DPI; TIRF; FRET; SFA; layer structure; solvent content; vertical diffusion; exponential growth; solid-liquid interface; deposition conditions; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. LÄS MER
