    Sammanfattning : Abstract There has been great interest in microgels as drug carriers within the pharmaceutical industry. This includes the use of amphiphilic drugs for treating conditions such as depression, allergies, and cancer. LÄS MER

  3. 2. 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.

  4. 3. Binding & Release of Biomolecules from Hyaluronic Acid Macrogels with Cetylpyridinium Chloride as a Model Surfactant

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för farmaci

    Författare :Sara Sandell; [2011]
    Nyckelord :hyaluronic acid; cetylpyridinium chloride; binding; release; biomolecules; macrogel;

    Sammanfattning : The purpose of this master thesis project was to investigate the penetration ofbiomolecules into hyaluronic acid (HA) macrogels. The investigations were performedboth in the presence and in the absence of the non-biodegradable surfactantcetylpyridinium chloride (CPC), which earlier has proved to form a micelle-rich shellat the gel surface.
