      The uniform deposition of a thin, protective alumina film by atomic layer deposition onto a SERS-active silver substrate improves the temporal stability of the substrate increasing the usable shelf life. In addition, the coating enables SERS measurements at higher temperatures compared to bare silver films, which is useful in a variety of applications. As a demonstration, the coated silver was used to measure the dehydration of calcium nitrate tetrahydrate at high temperature.

    2. Surface-enhanced Raman micro-spectroscopy of DNA/RNA bases adsorbed on pyroxene rocks as a test of in situ search for life traces on Mars (pages 12–15)

      Maurizio Muniz-Miranda, Cristina Gellini, Pier Remigio Salvi and Marco Pagliai

      This paper proposes an application of SERS spectroscopy to the remote inquiry of life traces on Mars. Adenine, guanine and a microRNA chain have been analyzed as test ligands for identifying traces of nucleic acids in Martian rocks and sediments. The SERS activation is ensured by deposition of silver colloidal nanoparticles onto pyroxene/nucleobase substrates.

    3. Micro Raman spectroscopy for monitoring alterations between human skin keratinocytes HaCaT and their tumorigenic derivatives A5RT3—toward a Raman characterization of a skin carcinoma model (pages 16–26)

      P. Donfack, M. Rehders, K. Brix, P. Boukamp and A. Materny

      Article first published online: 9 SEP 2009 | DOI: 10.1002/jrs.2400

      Raman scattering reveals intrinsic differences between non-tumorigenic HaCaT and tumorigenic A5RT3 cells. Differences interestingly scale linearly with the passage number of HaCaT, suggesting a correlation of tumorigenesis with their primarily genetic instabilities. HaCaT cells show greater lipid content and proteins mainly in ordered a-helical secondary structures, while A5RT3 have partly degraded and disordered proteins evidenced by the decreased signal intensity of the amide I, amide III and collagen α-helical marker bands, and exhibit changes in the phenylalanine ring-mode, indicating notable intracellular chemical environment modification partly due to modified lipid profiles.

    4. Micro-Raman spectroscopy and VP-SEM/EDS applied to the identification of mineral particles and fibres in histological sections (pages 27–32)

      Caterina Rinaudo, Mario Allegrina, Elisa Fornero, Maya Musa, Alessandro Croce and Donata Bellis

      Article first published online: 17 AUG 2009 | DOI: 10.1002/jrs.2403

      Micro-Raman spectroscopy and VP-SEM/EDS are employed to characterise inorganic particles/fibres directly in histological sections used for the cytological diagnosis. The results demonstrate that micro-Raman spectroscopy is a powerful technique to recognise the mineral phases of the fibres/particles incorporated in the biological system. By coupling the two techniques, it is possible to study the structural-chemical modifications that take place in the inorganic phases in contact with the cellular system.

    5. Characterisation of FXTAS related isolated intranuclear protein inclusions using laser tweezers Raman spectroscopy (pages 33–39)

      Tobias J. Moritz, James A. Brunberg, Denise M. Krol, Sebastian Wachsmann-Hogiu, Stephen M. Lane and James W. Chan

      Article first published online: 1 SEP 2009 | DOI: 10.1002/jrs.2436

      The vibrational modes of optically trapped, Fragile X-associated tremor/ataxia syndrome (FXTAS) related, isolated intra-nuclear protein inclusions are reported and analysed to determine protein composition and structure. The Raman spectroscopic results are correlated with previous mass spectrometry (MS) studies. Several potential spectroscopic markers for FXTAS are identified.

    6. Incorporation of Ag nanoparticles into membrane mimetic systems composed by phospholipid layer-by-layer (LbL) films to achieve surface-enhanced Raman scattering as a tool in drug interaction studies (pages 40–48)

      Pedro Henrique Benites Aoki, Priscila Alessio, Jose Antonio De Saja and Carlos José Leopoldo Constantino

      Article first published online: 21 AUG 2009 | DOI: 10.1002/jrs.2415

      Combining both the anionic phospholipid DPPG and negative Ag nanoparticles (AgNP), it was possible to form multilayered layer-by-layer (LbL) films. This approach allowed us applying SERRS to investigate a phenothiazine pharmaceutical compound within LbL films, which work as a biological membrane mimetic system.

    7. Growth profile of stimulated Raman anti-Stokes scattering influenced by fluorescence seeding in liquid-core optical fiber (pages 49–52)

      Zhi-Wei Men, Wen-Hui Fang, Zuo-Wei Li, Xiu-Ping Sun, Shu-Qin Gao and Guo-Hui Lu

      Article first published online: 19 AUG 2009 | DOI: 10.1002/jrs.2416

      It was demonstrated that the growth profile of stimulated Raman Stokes and anti-Stokes scattering of CS2 was influenced by the fluorescence seeding all-trans-β-carotene and rhodamine-B in liquid-core optical fibers. The intensity of the first-order Stokes signal was far away from the saturation intensity when the first-order anti-Stokes signal was built up, which was different from the neat CS2 because of the fluorescence enhancement effect. Simultaneously, the growth profile of the first-order Stokes and anti-Stokes signals was theoretically calculated with and without the fluorescence seeding by the coupled wave differential equations.

    8. Molecular structure, vibrational spectroscopic, first-order hyperpolarizability and HOMO, LUMO studies of 3-hydroxy-2-naphthoic acid hydrazide (pages 53–62)

      Lichen colonization in lava and wood substrata: Sixteen lichen specimens were analysed by Raman spectroscopy. Five protective pigments, whewellite and whedellite as well as chlorophyll and carotene were identified. The presence or absence of a particular pigment or oxalate is related with different protective strategies.

      Raman spectroscopy, complemented with infrared spectroscopy of compounds, equivalent to reevesite of the formula (Ni,Co)6Fe2(OH)16 (CO3)·4H2O with the ratio of Ni/Co ranging from 0 to 1, and the spectra related to the molecular structure of the synthesised mineral have been obtained. Variation in the position of the carbonate anion stretching vibrations occurs and is dependent on the Ni/Co ratio.

    13. Raman tensor elements for multiferroic BiFeO3 with rhombohedral R3c symmetry (pages 84–87)

      A quantitative assessment of the Raman spectrum emitted from a coarse-grained polycrystal of multiferroic BiFeO3 has been carried out by means of a polarized Raman microprobe. The dependence of the intensity of Raman phonon modes has been first theoretically modeled as a function of crystal rotation. Then, the Raman tensor elements have been experimentally determined from the analysis of the Ag and Eg vibrational modes.

    14. Low-temperature synthesis and Raman scattering of Mn-doped ZnO nanopowders (pages 88–92)

      Boqian Yang, Ashok Kumar, Noel Upia, Peter Feng and R. S. Katiyar

      Article first published online: 15 SEP 2009 | DOI: 10.1002/jrs.2397

      Nanocrystalline Mn-doped zinc oxides Zn1−xMnxO (x = 0–0.10) were synthesized by the sol–gel technique at low temperature. Temperature-dependent Raman spectra of ZnO nanopowder were carried out from 25 to 800 °C to check the presence of high luminescence at room-temperature Raman spectrum of ZnO powder. The suppression of luminescence at elevated temperature indicates that the surface-to-volume ratio of nanoparticles decreases with increase in temperature, which in turns increases the particle size above the critical limit.

      Experimental and theoretical studies on molecular structures of 2-bromonicotinic acid and 6-bromonicotinic acid are presented. The FT-IR (4000–400 cm−1 region) and FT-Raman (3500–50 cm−1 region) spectra have been recorded and the detailed vibrational assignments are reported for the first time. The most stable monomer conformers of the compounds were determined and according to these results the dimer conformations were analyzed with DFT/B3LYP using 6-311++G(d,p) level of theory. Reliable vibrational assignments were made on the basis of total energy distribution (TED), calculated with a scaled quantum mechanical (SQM) method.

      The basis set selection for the decomposition chemistry of Cd(CH3)2 was examined. Analyses demonstrated that the SDD/STO-3G/3-21G combination for Cd/C/H atoms best reproduces experimentally reported Cd-C vibrational stretchings of Cd(CH3)2 and •CdCH3. The selected basis set was used to examine other possible reactions, and Raman experiments successfully detected one of the suggested intermediates (CdCH3)2.
