1. Exploring alternative surfactants to replace PEG within lipid nanoparticles
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master); Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)Abstract : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. READ MORE

2. Green Coacervates for Pharma and Food
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : Anionic biosurfactant-cationic biopolymer systems were investigated to identify and characterize a coacervation window. The characterization of the systems was performed with dynamic light scattering, small angle x-ray scattering and in-situ ellipsometry. READ MORE

3. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. READ MORE

4. The influence of salt in the formation of carboxylic functionalized mesoporous silica
University essay from Lunds universitet/Kemiska institutionenAbstract : Popular summary This master thesis was focused on the influence of salt, such as NaCl and CaCl2, in the formation of carboxylic functionalized mesoporous silica materials. Mesoporous silica materials are one type of porous materials with a pore size between 2 and 5 nm (1݊݉ = 0.000000001 ݉ ). READ MORE

5. Investigation of the micelle-to-vesicle transition in mixtures of an anionic and a cationic surfactant: the effect of adding salt
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : Catanoinic systems spontaneously form micelles and vesicles, which are self-assembled spherical structures made up by surfactants. In the core of the micelle a drug, or other organic substance, can be kept to stabilize it when placed in an aqueous environment. READ MORE
