  1. 16. GENOME2QUNOME : Interfacing Molecules with Nanomaterials

    Författare :Pritam Kumar Panda; Rajeev Ahuja; Yogendra Kumar Mishra; Helder Almeida Santos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electronic transport; Contact electrification; Nanomaterials; Zinc Oxide; Tetrapods; 2D-materials; Density functional theory; Non-equilibrium Green s function; Molecular docking; Molecular dynamics simulation; Materialvetenskap; Materials Science; Theoretical Physics; Teoretisk fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : The advent of technological furtherance in the biomedical sector and the renaissance of interdisciplinary science enable us to comprehend human lifestyle, and diseases at molecular and nanoscale levels. Lacking a shared theoretical foundation and terminological lexicon between various scientific domains might impede efforts to incorporate biological principles into nanoscience. LÄS MER

  3. 17. Supported Lipid Membranes and Their Use for the Characterization of Biological Nanoparticles

    Författare :Silver Jõemetsa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; supported lipid bilayer; lipophilic dyes; size determination; diffusion; microfluidics;

    Sammanfattning : Biological nanoparticles (BNPs) are nano-sized lipid vesicles of biological origin, which are involved in multiple biological processes. BNP characterization techniques are critical for improving the understanding of how these particles contribute to cellular communication, viral infections and drug-delivery applications. LÄS MER

  4. 18. Biological Laboratory X-Ray Microscopy

    Författare :Mikael Kördel; Hans Hertz; Ulrich Vogt; Jonas A. Sellberg; Rajmund Mokso; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray microscopy; laboratory x-ray microscopy; water window; biological; cell imaging; virus; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik; Optik och fotonik; Optics and Photonics;

    Sammanfattning : Soft x-ray microscopy in the water window (? ≈ 2.3 − 4.3 nm) is a powerful technique for high-resolution biological imaging. The strong natural contrast between carbon-based structures and water allows visualization of hydrated and unstained samples, while providing enough transmission through up to ∼ 10 μm of organic matter.

  5. 19. Theoretical Studies of G-Protein-Coupled Receptors

    Författare :Xianqiang Sun; Yaoquan Tu; Lennart Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological Physics; Biologisk fysik;

    Sammanfattning : The family of G-protein-coupled receptors (GPCRs) contains the largest number of drug targets in the human body, with more than a quarter of the clinically used drugs targeting them. Because of the important roles GPCRs play in the human body, the mechanisms of activation of GPCRs or ligands binding to GPCRs have captivated much research interest since the discovery of GPCRs.

  7. 20. Biophysical Studies of Apolipoprotein A-IM and a Partitioning study

    Författare :Malin Suurkuusk; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apolipoprotein A-IMilano; Apolipoprotein A-I; Lipoprotein; Lipid; Microcalorimetry; DCS; Denaturation; Guanidine Hydrochloride; Physics; Fysik; Chemistry; Kemi;

    Sammanfattning : The major part of this thesis deals with the similarities and differences in some biophysical properties of apolipoprotein A-I (apo A-I) and the molecular variant apolipoprotein A-IMilano (apo A-IM), and the influence on lipid binding. A model compound partitioning study has also been performed. LÄS MER
