Unusual Raman spectra of para-nitroaniline by sequential Fermi resonances

In this communication, we report the unusual Raman spectra of para-nitroaniline (PNA) by sequential Fermi resonances. The combinational mode 1292 cm-1 in the experimental Raman spectrum indirectly gains...

Insight into vibration mode-resolved plasmon enhanced Raman optical activity

Vibration mode-resolved plasmon enhanced Raman optical activities (PE-ROA) are investigated experimentally and theoretically. It is found that the profile of PE-ROA is significantly different from that...

Raman-Spectroscopy Based Cell Identification on a Microhole Array Chip

Circulating tumor cells (CTCs) from blood of cancer patients are valuable prognostic markers and enable monitoring responses to therapy. The extremely low number of CTCs makes their isolation and characterization...

ATR-FTIR and Raman spectroscopy of primary and permanent teeth

BACKGROUND: Valuable structural and chemical properties can be obtained for dentin and enamel by vibrational spectroscopy. A better understanding of structural and chemical changes in deciduous dentition...

Phenalenone-type phytoalexins mediate resistance of banana plants (Musa spp.) to the burrowing nematode Radopholus similis

The global yield of bananas—one of the most important food crops—is severely hampered by parasites, such as nematodes, which cause yield losses up to 75%. Plant–nematode interactions of two banana...

Goldbeschichtungen für BRAGG-Gitter-Fasersensoren

Der Einsatzbereich optischer Glasfasern wird durch eine Metallbeschichtung in vielfältiger Weise erweitert. Gegenwärtig ist beispielsweise der thermische Einsatzbereich üblicher Polymer-beschichteter...

Raman spectroscopic identification of single bacterial cells under antibiotic influence

The identification of pathogenic bacteria is a frequently required task. Current identification procedures are usually either time-consuming due to necessary cultivation steps or expensive and demanding...

Nanoflower-based SERS active particles for chemosensing

Isolation und Anreicherung von Krankheitserregern mit Hilfe eines oberflächenmodifizierten Aluminium-Chips für Raman-spektroskopische Anwendungen

Wir haben einen Raman-kompatiblen Chip zur Isolation von Mikroorganismen aus komplexen Medien entwickelt. Die Isolation der Bakterien wird unter Verwendung von Antikörpern als Fängermoleküle erreicht....

Comparison of Electric Field Induced Second Harmonic (EFISH) in reflection and transmission from an oxidized silicon membrane
