7,7′-Disubstituted 2,2′-methylenedioxy-1,1′-binaphthyls are highly efficient chirality inducers in nematic liquid crystals. The absolute configuration of these compounds is, however, hard to determine as they only crystallize as racemic mixture

Optical properties and SERS efficiency of tunable gold/silver nanoshells

Autor: Magdalena Gellner, Sebastian Schlücker, Bernd Küstner

Publikováno v: Vibrational Spectroscopy. 50:43-47

Tunable hollow Au/Ag nanospheres with an outer particle diameter of 55 nm and extinction maxima in the range of 600–700 nm were synthesized. An increasing amount of gold in the preparation of the colloids leads to a red shift of the plasmon band. A

SERS Labels for Red Laser Excitation: Silica-Encapsulated SAMs on Tunable Gold/Silver Nanoshells

Autor: Magdalena Gellner, Friedrich Schöppler, Philipp Ströbel, Carsten Schmuck, Sebastian Schlücker, Alexander Marx, Bernd Küstner, Max Schütz, Patrick Adam

Publikováno v: Angewandte Chemie International Edition. 48:1950-1953

In a glass house: Silica-encapsulated self-assembled monolayers (SAMs) on tunable gold/silver nanoshells were used as labels for surface-enhanced Raman scattering (SERS). This concept combines the spectroscopic advantages arising from maximum surface

Publikováno v: Small (Weinheim an der Bergstrasse, Germany). 6(6)

Surface-enhanced Raman scattering (SERS) combines the benefits of vibrational Raman scattering with highest sensitivity, using nanostructures that can support localized plasmon resonances. [1‐4] The main application of SERS is the label-free detect
