Chiral plasmonic nanostructures with tunable handedness-dependent absorption in the visible and infrared offer chiro-optical control at the nanoscale. Moreover, coupling them with emitting layers could lead to chiral Nano sources, important for nanophotonic circuits. Here, we propose plasmonic elliptical nanohole arrays (ENHA) for circularly dependent near-infrared and visible emission. We first investigate broadband chiral behavior in an Au-ENHA embedded in glass by exciting it with plane waves. We then study the coupling of ENHA with a thin emitting layer embedded in glass; we focus on the...

Electroporation is a membrane phenomenon which involves fundamental behavior of cell and artificial bilayer membranes. Electroporation is usually described as a formation of transient pores in the cell membrane in the presence of a strong electric field, which enables transport of molecules and ions across the cell membrane and increasingly attracts consideration for applications in biology, biotechnology and medicine. Understanding the basic mechanisms underlying electroporation is therefore important and provides the motivation of this thesis.Several experimental studies of electroporation...
