  1. 1. Synthesis and characterization of amine-functionalized microgel particles and their subsequent assembly into colloidal molecule-like clusters by droplet-based microfluidics

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Emil Gustafsson; [2015]
    Nyckelord :Physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : The ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subsequent assembly into clusters using droplet-based microfluidics, with the goal of forming responsive colloidal molecules with well-defined valency.

  3. 2. Characterization of enzyme sensitive responsive hydrogel/lipid system for triggered release

    Master-uppsats, Institutionen för farmaci

    Författare :Pétur Jónsson; [2013]
    Nyckelord :enzyme sensitive responsive hydrogel lipid system for triggered release; liposomes; mesoporous silica; ellipsometry; coating;

    Sammanfattning : This master thesis aimed to create and characterize multilayer coatings upon mesoporous silica particles (MSP). The properties of the coating aimed for, was to have a triggerable controlled release, where a targeted enzyme within the intestine, alpha-amylase, is supposed to degrade the coating. LÄS MER

  4. 3. Separation of Deformable Hydrogel Particles in the Deterministic Lateral Displacement Devices

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Masoomeh Ghasemi; [2012]
    Nyckelord :microfluidics; cell separation; deformability; hydrogel particles; Physics and Astronomy;

    Sammanfattning : Klassificerning av biologiska och icke-biologiska partiklar är av avgörande betydelse inom många forskningsområden och inom industrin, inbegripet biologi, medicin och så kalladtissue engineering. Gemensamma parametrar i inmärknings-fri separationutgörs vanligen av storleken, formen och de mekaniska egenskaperna hos partiklarna. LÄS MER
