Abstract:

The detection of specific DNA sequences is of increasing interest due to the sequencing of the human genome. This can be achieved by the use of covalently labelled oligonucleotide probes detected by sensitive analytical techniques. Surface Enhanced Resonance Raman Scattering (SERRS) spectroscopy is one such technique that provides molecularly specific information about probes at very low concentrations. The enhancement results from adsorption of a chromophore within the probe to a roughened metal surface. Specific SERRS probes were synthesised using benzotriazole as the metal complexing agent

Abstract:

Die Raman-Spektroskopie ist eine der nützlichsten optischen Methoden zur Untersuchung der Phononen organischer und anorganischer Materialien. Mit der fortschreitenden Miniaturisierung von elektronischen Bauelementen und der damit einhergehenden Verkleinerung der Strukturen von der Mikrometer- zur Nanometerskala nehmen das Streuvolumen und somit auch das Raman-Signal drastisch ab. Daher werden neue Herangehensweisen benötigt um sie mit optischer Spektroskopie zu untersuchen. Ein häufig genutzter Ansatz um die Signalintensität zu erhöhen ist die Verwendung von Resonanz-Raman-Streuung, das heißt

Abstract:

To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. One possible route to achieve this is through biosensing based on plasmonic nanostructures, which during the last decade have demonstrated impressive diagnostic capabilities. These nanoplasmonic surfaces have the ability to significantly enhance fluorescence- and Raman signal

Abstract:

Surface- and tip-enhanced resonant Raman scattering (resonant SERS and TERS) by optical phonons in a monolayer of CdSe quantum dots (QDs) is demonstrated. The SERS enhancement was achieved by employing plasmonically active substrates consisting of gold arrays with varying nanocluster diameters prepared by electron-beam lithography. The magnitude of the SERS enhancement depends on the localized surface plasmon resonance (LSPR) energy, which is determined by the structural parameters. The LSPR positions as a function of nanocluster diameter were experimentally determined from spectroscopic micro

Raman spectroscopy is a powerful tool in the field of biomedicine for disease diagnosis owing to its potential to provide the molecular fingerprint of biological samples. However due to the inherent weak nature of the Raman process, there is a constant quest for enhancing the sensitivity of this technique for enhanced diagnostic efficiency. This thesis focuses on achieving this goal by integrating advanced methods with Raman spectroscopy.

The fabrication routine is ready for wafer-scale production involving only low-energy ion beam irradiation and metal deposition.

However, the availability of rapid, robust high-throughput screening methods has often limited the impact of directed evolution in discovering enzymes with enhanced catalyst performance. Raman spectroscopy is an established analytical technique, providing molecular specific information, permitting analysis in aqueous solutions and as such is an attractive, alternative screening method for biological systems.

Raman spectroscopy is a promising technique because it contains abundant vibrational chemical information.

In the first part of my dissertation, I investigate two coherent Raman processes, coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS). In CARS project, I
