  1. 1. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Karnsinee Viriyayudhakorn; [2023]
    Keywords : human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

    Abstract : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. READ MORE

  3. 2. The influence of molecular structure of phospholipids on the transition from micelles to bilayers in bile salt surfactant/phospholipid mixtures

    University essay from Uppsala universitet/Institutionen för läkemedelskemi

    Author : Zeyneb Alkademi; [2020]
    Keywords : phospholipids; micelles; bilayers; bile salt; surfactant;

    Abstract : Phospholipid molecules self-assemble to form bilayers that are poorly soluble in an aqueous solvent. Phospholipids may, however, be readily dissolved by mixing with a bile salt or amphiphilic drug surfactant that forms mixed surfactant/phospholipid micelles. READ MORE

  4. 3. Coumarin-based molecular probes : exploring the spectroscopic properties of complex mixtures and applications in colloid chemistry

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Shangqing Zhao; [2018]
    Keywords : warfarin; phenprocoumon; fluorescence spectroscopy; ultraviolet absorption spectroscopy; sodium dodecyl sulfate; surfactant; micelles; critical micelle concentration.;

    Abstract : Warfarin is a well-known anticoagulant drug that is used to prevent cardiovascular disease and blood coagulation such as thrombosis. In this study, the main aim was to investigate the photo physical characteristics of warfarin in the different molecular environments provided by sodium dodecyl sulfate (SDS) micelles by using ultraviolet absorption and fluorescence emission spectroscopic techniques.

  5. 4. Efficiency of liposomal and micellar emulsifiers during homogenization

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ellen Sunneskär; [2012]
    Keywords : Nanokemi; Chemistry;

    Abstract : The coalescence of emulsion droplets during the homogenization process is governed by the emulsifier adsorption rate. This is in turn affected by the size and shape of the adsorbing molecule which can be dependant of the aggregation states. READ MORE

  6. 5. Self-assembly in mixtures of an anionic and a cationic surfactant: A comparison between static light scattering and cryotransmission electron microscopy

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Sara Skoglund; [2011]
    Keywords : surfactants; mixed micelles; vesicles; static light scattering; cryo-transmission electron microscopy;

    Abstract : Surfactants self-assemble into aggregates above a certain concentration. In this work mixtures of the cationic surfactant cetyltrimetylammonium bromide (CTAB) and the anionic surfactant sodium octyl sulfate (SOS) were investigated systematically. READ MORE
