Cytotoxic Effects of Combination of Oxidosqualene Cyclase Inhibitors with Atorvastatin in Human Cancer Cells

Ten oxidosqualene c-yclase inhibitors with high efficacy as cholesterol-lowering agents and of different chemical structure classes were evaluated as potential anticancer agents against human cancer cells from various tissue origins and nontumoral human-br ...

Retardation-induced plasmonic blinking in coupled nanoparticles

Olivier Martin, Holger Fischer

We study how retardation leads to interference effects in radiatively coupled plasmonic nanoparticles. We show that inclined illumination through a glass substrate on two plasmonic particles results in either an enhanced field or an attenuated field locali ...

Mode-Selective Surface-Enhanced Raman Spectroscopy Using Nanofabricated Plasmonic Dipole Antennas

Olivier Martin, Holger Fischer, Thomas Schmid

Mode-selective surface-enhanced Raman spectroscopy (SERS) is demonstrated using plasmonic dipole antennas fabricated with electron beam lithography. An similar to 10x change of the relative enhancement between two different Raman modes is observed when the ...

Enhancement and subwavelength confinement of light in plasmonic nanostructures

Holger Fischer

This work includes the fabrication of plasmonic nanostructures as well as the investigation of their optical properties in the near-field and in the farfield. As expressed in the title of this thesis the focus lies in the subwavelength confinement and enha ...

Engineering the optical response of plasmonic nanoantennas

Olivier Martin, Holger Fischer

The optical properties of plasmonic dipole and bowtie nanoantennas are investigated in detail using the Green's tensor technique. The influence of the geometrical parameters (antenna length, gap dimension and bow angle) on the antenna field enhancement and ...

Polarization sensitivity of optical resonant dipole antennas

Olivier Martin, Holger Fischer

The polarization sensitivity of optical resonant dipole antennas is investigated numerically using the Green's tensor technique. The electric field-intensity in the feed-gap of the antenna is calculated as function of the polarization of the incident field ...

Tunable plasmonic nanostructures

Olivier Martin, Holger Fischer

We discuss different composite plasmonic nanostructures, which optical properties can be tuned by displacing some of their parts at the nanoscale. The actuation of these structures with MEMs will define new optical functionalities. ...
