  1. 1. Transient state UV spectroscopy of Tyrosine and Tyrosine-containing protein

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Hongjian Chen; [2023]
    Nyckelord :Tyrosine; Calmodulin; Autofluorescence; Transient-state monitoring; Electronic state transitions; Tyrosin; Calmodulin; Autofluorescens; Transient-tillståndsövervakning; Elektroniska tillståndsövergångar;

    Sammanfattning : The aromatic amino acids tryptophan, tyrosine, and phenylalanine have been extensively used for different label-free protein studies. These investigations extract information on protein conformations and interactions from the emitted fluorescence's intensity, wavelength, and/or polarization. LÄS MER

  3. 2. Towards the Development of the Dual Modal Contrast Agent for Computed Tomography and Ultrasound

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Hongjian Chen; [2016]
    Nyckelord :Computed tomography; Ultrasound; Hybrid contrast agents; Polyvinyl alcohol;

    Sammanfattning : Nowadays hybrid imaging modalities are new trends in medical imaging. To improve the diagnostic outcome of hybrid imaging, multimodal contrast agents need to be developed. For example, hybrid contrast agents for computer tomography and ultrasound (CACTUS) are one of those desirable hybrid contrast agents for the modern medical imaging. LÄS MER
