4. 3. Analysis of surface coverage in regards to surface functionalization : A microscopic approach

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Daniel Leppälä; [2017]
   Nyckelord :Neutrophils; sensor; cell clinic; fluorescent microscopy; image analysis;

   Sammanfattning : The understanding of how white blood cells react when coming into contact with various surfaces is of major importance for a wide range of biomaterials and biosensor applications. In this study it is investigated if it is possible to determine how neutrophils react to a certain type of sensor chip called cell clinic being developed. LÄS MER

7. 5. Suitability of Spray Dried Powder containing Lipids for Inhalation Formulation based on Fine Particle Fraction and Particle Size Distribution

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Hung Nguyen; [2016]
   Nyckelord :Fine Particle Fraction: Particle Size Distribution; Drying; Inhalation; DPI; Dry Powder Inhaler; Powder; Inhaler; Spray drying; Lipids; Inhalation Formulation; Lysozyme; Pharmaceutical Technology; läkemedelsteknologi; Technology and Engineering;

   Sammanfattning : The aim of this master thesis is to provide an indication of the suitability, or otherwise usage, of spray-drying for production of powder aimed for inhalation formulation and comparing the characteristics of the product, with and without lipids. Lipids have a proven effect of delaying release of active drug substances in the cardiovascular system and pulmonary systemic delivery has a number of advantages, chiefly among them being bypassing the first pass metabolism.
