etallic nanowires, due to their plasmonic character
combinedwiththeabilitytoefficientlytransportexcitations,
are highly suitable for controlling the optical properties of
other nanostructures, such as polymers, nanocrystals or
biomolecules. Importantly, while diameters of such nanowires,
in the range of 100 nm, are small enough to exhibit plasmonic
effects in the broad spectral range, their lengths exceeding tens
of micrometers make them visible using standard microscopy.
In addition, by functionalizing their surface, it is possible to tailor
their biochemical function, for instance as sensors. In the talk,
we will discuss selected experiments carried out using silver
nanowires as building blocks of hybrid nanostructures. The
first result was obtained by attaching photosynthetic pigment-
protein complexes to the nanowires, where we demonstrate
strong enhancement of fluorescence of these complexes due
to plasmonic interactions. Additional effects associated with
controlled geometry of this assembly will be discussed. Next,
we describe the application of silver nanowires for enhancing
absorption of organic polymers and macromolecular systems
used in organic electronics. In this case, optical spectroscopy
allows elucidating the processes responsible for the observed
effects and enables for further optimization of actual devices.
The final part of the presentation will focus on applying silver
nanowires as a sensing platform for various species. Particular
emphasis will be placed on methods of spatial positioning of
such nanowires in a controlled manner on the surface, as this
seems to be the key for any possible application.
