- Abstract
In this contribution a nanodevice based on Localized Surface Plasmon Resonance (LSPR) phenomenon for biological characterization operating in the Visible and Near Infrared frequency Regime is proposed. The device consists of coupled biconical nanoparticles deposited on a silica substrate. By using a very small inter-particle distance it is possible to obtain a strong near electric field enhancement at the resonant wavelength suitable for ultra-sensitive biosensing applications. Full-wave simulations confirm the possibility to use the device as an optical sensor to detect in a ultra-sensitive way different cholesterol concentrations of the lipid membrane.
