Journal ArticleDOI
Biomolecular Recognition Based on Single Gold Nanoparticle Light Scattering
Gunnar Raschke,Stefan Kowarik,Thomas Franzl,Carsten Sönnichsen,Thomas A. Klar,Jochen Feldmann,Alfons Nichtl,K. Kürzinger +7 more
TL;DR: A method for biomolecular recognition is reported using light scattering of a single gold nanoparticle functionalized with biotin, resulting in a spectral shift of the particle plasmon resonance.
Journal ArticleDOI
Gold nanoshells improve single nanoparticle molecular sensors
Gunnar Raschke,S. Brogl,Andrei S. Susha,A. L. Rogach,Thomas A. Klar,Jochen Feldmann,B. Fieres,Nikolay Petkov,Thomas Bein,Alfons Nichtl,K. Kürzinger +10 more
TL;DR: In this article, the authors focus on the narrow homogeneous line width of only 180 meV and show that the particle plasmon resonance responds more sensitively to changes in the environment, the biological spectral window is accessible and the scattering spectra show sharper resonances.
Journal ArticleDOI
Gold nanostoves for microsecond DNA melting analysis.
Joachim Stehr,Calin Hrelescu,Ralph A. Sperling,Gunnar Raschke,Michael Wunderlich,Alfons Nichtl,Dieter Heindl,K. Kürzinger,Wolfgang J. Parak,Thomas A. Klar,Jochen Feldmann +10 more
TL;DR: It is shown that double-stranded DNA melts on a microsecond time scale that leads to a disintegration of the gold nanoparticle aggregates on a millisecond time scale, indicating a perfectly matching and a point-mutated DNA sequence can be clearly distinguished in less than one millisecond even in a 1:1 mixture of both targets.
Journal ArticleDOI
Linewidth-limited energy transfer in single conjugated polymer molecules.
J. G. Müller,Uli Lemmer,Gunnar Raschke,Marco Anni,Ullrich Scherf,John M. Lupton,Jochen Feldmann +6 more
TL;DR: Using low temperature single molecule spectroscopy on rigid-rod conjugated polymers the authors are able to identify homogeneously broadened, strongly polarized emission from individual chromophore units on a single chain.
Journal ArticleDOI
Moving nanoparticles with Raman scattering.
M. Ringler,Thomas A. Klar,A. Schwemer,Andrei S. Susha,Joachim Stehr,Gunnar Raschke,Stefan Funk,Borowski M,Alfons Nichtl,K. Kürzinger,Phillips Rt,Jochen Feldmann +11 more
TL;DR: It is found that low-intensity laser light in resonance with the nanoparticle-dimer plasmon provokes a change of the inter-nanoparticle distance on the order of 0.5 nm whenever SERS from the proteins connecting the nanoparticles can be observed.
