Seminarium Fizyki Ciała Stałego

The presentation will focus on advocating for uniqueness of silver nanowires, metallic structures with diameters of 100 nm and lengths up to a millimeter [1]. While the diameter of the nanowires is small enough to facilitate localized surface plasmon resonance, their length is sufficiently large to exploit propagation of energy over considerable distances. In combination with advanced nanostructural manipulation, these properties open virtually unlimited playground for interdisciplinary research, which spans over fluorescence enhancement [2-4], remote and high efficiency sensing [5-7], long-range energy propagation [8-10], controlled photocatalysis, heat propagation, etc.As all of the experiments involve some form of fluorescence microscopy and spectroscopy, surface functionalization, microdroplet deposition, and alike, essentials of the technical aspects will be discussed to the necessary detail.Experimental demonstrations will include:1. Plasmonic enhancement of protein fluorescence2. Real-time single protein detection3. Remote activation of luminescence4. Interfacing nanowires with quantum dots5.
