  1. 1. Comparison and optimization of extracellular vesicle (EV) capturing on functional thin films for their molecular profiling

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Prattakorn Metem; [2023]
    Nyckelord :extracellular vesicle; plasmonic nanohole array; atomic force microscopy; fluorescence analysis; extracellulära vesiklar; nanohålsuppsättning; atomkraftsmikroskopi; fluorescensanalys;

    Sammanfattning : Extracellular vesicles (EVs) are lipid bilayer encapsulated nanoparticles which have emerged as an excellent source of biomarkers for multiple diseases, including cancer. However, they are highly heterogeneous in their molecular compositions which remains a major challenge hindering the utilization of their biomarker potential. LÄS MER

  3. 2. Diffusion and Camera-Noise Modelling for Analysis of Single-Particle Tracking Movies

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Erik Clarkson; [2022]
    Nyckelord :reaction-diffusion; camera-noise modelling; single-particle tracking; Gillespie simulations; Physics and Astronomy;

    Sammanfattning : Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. LÄS MER

  4. 3. Molecular Mechanisms of Endophilin B1-Bax Macromolecular Complexes in Membrane Permeabilization and Cell Death

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Tobias Kollberg Hedström; [2022]
    Nyckelord :;

    Sammanfattning : A crucial step during apoptosis is the accumulation of the pro-apoptotic protein Bax on the mitochondria where it triggers permeabilization of the outer membrane. This causes the release of cytochrome c into the cytosol and is considered a point of no return in programmed cell death. LÄS MER

  5. 4. Strain-induced nonlinear Hall effect in graphene systems

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Pedram Pakmehr; [2022]
    Nyckelord :;

    Sammanfattning : This thesis aims to study the nonlinear electrical transport response of monolayer and bilayer graphene systems under the influence of different lattice deformations (strain). Broken inversion and rotation symmetries can generate a second-order transverse current response called the nonlinear Hall effect in the presence of time-reversal symmetry. LÄS MER

  7. 5. Development of a novel method for studying permeability of PEG-ylated liposomes

    Master-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Jicheng Li; [2021]
    Nyckelord :;

    Sammanfattning : PEG-ylated liposomes are attractive in terms of utilizing them as long-circulating drug carriers. With the incorporation of PEG-components in the liposomal membranes, their permeability towards small-molecule solutes may be affected for various reasons. LÄS MER
