Resum:
The self-assembly of molecules into nano- or microstructures is an area of intense interest, with lipids being particularly attractive in the formation several structures including liposomes. There are numerous methods reported for the preparation of liposomes, however, time-consuming preparative steps resulting in heterogeneous liposome populations of incontrollable size, the use of organic solvents and the need of further size-reducing steps are the drawbacks limiting wide-spread use of liposomes. Therefore; the main concern of this PhD thesis is optimization of a one-step, organic solvent-free, ultra rapid method for the preparation of liposomes. So called “Curvature tuned preparation method” was later implemented in several lipid formulations which resulted in liposomes and other lipid superstructures. Those structures were further used in several applications, such as nanoreactors and templates for tailored synthesis of gold nanoparticles, enzyme encapsulating liposomes as signal enhancers in immunosensor development, and finally as carriers for controlled release of drugs
