  1. Raman spectroscopy in experimental oral carcinogenesis: investigation of abnormal changes in control tissues

    Raman spectra acquired from controls – exposed to varying degree of forceps handling (vehicle control, vehicle contralateral, and carcinogen contralateral) – were evaluated against histopathology/immunohistochemistry-based models. Findings suggest that RS can identify micro-changes, including squamous cell carcinoma, probably owing to repeated irritation. Chronic irritation is a known etiological agent for oral cancers. Thus, the present study further demonstrated the efficacy of Raman spectroscopy as a potential tool for screening, in both high-risk and non-tobacco habitués groups, vis-à-vis conventional screening, which is shown to be more effective in high-risk population.

    In the archaeological Khmer complex (Cambodia), an unusual black patina covering both the exterior and interior walls of the Neang Khmau temple has been observed during a recent archaeological survey.

    Optical observations of the cross sections have evidenced irregularities in the thickness of the patina. Raman and FTIR spectra have revealed that the black layers are mainly composed of manganese minerals (hollandite, romanechite and manganite). This peculiar alteration pattern is interpreted as because of the tropical climatic conditions of Cambodia.

  3. Micro-Raman spectroscopic investigations of extremely scarce Pb–As sulfosalt minerals: baumhauerite, dufrénoysite, gratonite, sartorite, and seligmannite

    Baumhauerite (Pb3As4S9), dufrénoysite (Pb2As2S5), gratonite (Pb9As4S15), sartorite (PbAs2S4), and seligmannite (PbCuAsS3) were investigated by Raman spectroscopy. Raman spectra of the investigated minerals arise from the stretching (between 390 and 340 cm−1) and bending (335 and 220 cm−1) modes of the isolated and interconnected AsS3 pyramidal groups. The As–S shorter bond lengths readily elucidate the blue shift from seligmannite to gratonite, sartorite, dufrénoysite, and baumhauerite and the increase in full width at half maximum in similar modes.

  4. Phase-specific Raman analysis of n-alkane melting by moving-window two-dimensional correlation spectroscopy

    Moving-window two-dimensional correlation spectroscopic (MW-2DCOS) analysis of n-C21H44 determines the phase transition temperatures with a higher resolving power and resolves two narrow overlapping peaks embedded in the Raman CH2 twisting band in the orthorhombic phase.

  5. Towards quantitative multi-color nanodiagnostics: spectral multiplexing with six silica-encapsulated SERS labels

    Max Schütz and Sebastian Schlücker

    Version of Record online: 14 JUN 2016 | DOI: 10.1002/jrs.4913

    Thumbnail image of graphical abstract

    Quantitative multiplexing experiments using mixtures of up to six spectrally distinct surface-enhanced Raman scattering (SERS) nanoparticle labels are demonstrated. The SERS labels comprise gold nanoparticles, Raman reporter molecules chemisorbed onto the metal surface, and a silica shell providing chemical and mechanical stability as well as spectral reproducibility. Spectral unmixing is performed with a simple least-square algorithm because the overall SERS signal of the mixtures can be represented as a linear combination of the known spectral signatures from the individual silica-protected labels.
