  2. 6. Topical formulations, design and drug delivery : "A dive into water"

    Author : Abdullah Ali; Marie Lodén; Anan Yagmur; Anders Hall; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; water; topical formulations; Pickering emulsion; skin cream; drug delivery; tactile friction; sensory panel; nasal; buccal; mucosa; skin; triglycerides; ethanol; drug transport; cosmetic appeal;

    Abstract : Water is a vital component regulating the properties of topical formulations and their interaction with biological barriers, such as skin and mucosa. Changing the watercontent within the frame of the pharmaceutical triangle will have a huge impact on which type of formulation, such as a cream, ointment, gel, or lotion, is formed, as well as the physical properties of the formulation.

  4. 7. Fabrication of Functional Molecularly Imprinted Materials using Nanoparticle Building Blocks

    Author : Changgang Xu; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymers; magnetic susceptibility; click chemistry; PFPA; Pickering emulsion; chemical conjugation;

    Abstract : Molecularly imprinted polymers (MIPs) have attracted great interest in many applications including bioseparation, chemical sensing, catalysis, drug delivery, etc. Recently, molecularly imprinted nanoparticles have become accessible due to a number of synthetic methods that have been developed.

  5. 8. Perfluorocarbon microdroplets stabilized by cellulose nanofibers : Toward ultrasound-mediated diagnostics and therapy

    Author : Ksenia Loskutova; Dmitry Grishenkov; Anna Justina Svagan; Gaio Paradossi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; acoustic droplet vaporization; phase-change contrast agent; Pickering emulsion; cellulose nanofiber; Ultraljud; akustisk droppförångning; kontrastmedel med fasförändring; Pickeringemulsion; cellulosananofiber; Teknik och hälsa; Technology and Health;

    Abstract : Ultrasound contrast agents consist of gas-filled micrometer-sized bubbles that are injectedinto the blood stream. Ultrasound contrast agents are an invaluable tool for ultrasound imaging of the cardiac muscle and highly vascularized structures such as kidneys and the liver. READ MORE

  6. 9. Functionalization and characterization of aqueous silica sols and their application in Pickering emulsions

    Author : Sanna Björkegren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pickering emulsions; functionalized colloidal silica; surface activity; NMR spectroscopy;

    Abstract : The main objective of this thesis is to create an understanding of how surface functionalized colloidal silica can be utilized in emulsions stabilized solely by particles, so called Pickering emulsions. To achieve this, water-based silica sols have been functionalized with hydrophilic and hydrophobic groups. READ MORE

  7. 10. Cellulose Dissolution and Amphiphilicity : Insights on the Emulsion Formation and Stabilization

    Author : Carolina Costa; Magnus Norgren; Håkan Edlund; Orlando Rojas; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An amphiphilic polymer is expected to adsorb at the oil-water interface and be capable of stabilizing emulsions. Cellulose derivatives, cellulose nanoparticles and regenerated cellulose particles show an intrinsic amphiphilic character by self-assembling at oil-water interfaces and stabilizing emulsions without the aid of surfactants or any other co-stabilizers.
