2. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing
Abstract : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.

4. Liposomes for mucosal vaccine delivery: physicochemical characterization and biological application
Abstract : Liposomes are attractive vaccine carriers due to their potential to act as adjuvants, and to the fact that their composition and characteristics are virtually endlessly customizable. However, the precise physicochemical profile of an ideal carrier liposome for mucosal vaccines is still widely unknown, and how different properties affect key steps in the acquisition of protective immunity remains to be elucidated.

5. Multiparametric Optical Characterization of Biological Nanoparticles using Evanescent Field Sensing
Abstract : In light of the increasingly realized dependence of many biological functions on nanoscopic supramolecular assemblies, also including novel biotechnological applications, there is a need for advanced analysis methods capable of accurately quantifying different characteristics of these elusive entities. The prime aim of this thesis is the development and utilization of surface-based bioanalytical sensing methods for quantitative characterization of biological nanoparticles. READ MORE
