    Sammanfattning : A new rising star in the carbon nanomaterial family is carbon dots. Carbon dots have received great attention due to their excellent luminescence and low toxicity. In this project, a new carbon dot derived from birch leaves is studied and characterized. LÄS MER

  3. 2. 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
