Proof of principle in the current work involves activating an organic monolayer by attaching silver nanoparticles. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23932&type=Feature&page=1 The rapid identification of mixtures of crystal meth by Raman spectroscopy without the need for a separation technique is discussed as an alternative to GC/MS. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23894&type=Feature&page=1 Polydimethylsiloxane can be used to produce wrinkles on a glass surface to pattern lines of gold which are twice as effective as conventional SERS substrates, according to German and Spanish researchers. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23805&type=Feature&page=1 Iznik tiles dated from the 16th century, copies of tiles and pottery of Theodore Deck from the 19th century, and also tiles without any information on their origin were analyzed with both laboratory and portable Raman instruments. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23777&type=Feature&page=1 Italian researchers have used salver of techniques, including microscopic Raman and Fourier transform infrared (FTIR) spectroscopies, X-ray diffraction and scanning electron microscopy-energy dispersive X-ray to study powdered pigments found in bowls from the Pompeii archaeological site as well as wall-painting fragments from the Vesuvian region. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23629&type=Feature&page=1 Well-resolved Raman spectra of organic acids were successfully obtained under field conditions using a portable Raman instrument under low-temperature atmospheric conditions at an altitude of 2000 m. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23595&type=Feature&page=1 Surface-enhanced Raman scattering (SERS) can be used in a new microarray approach to microbial detection that is label-free, according to researchers writing in the April issue of the journal Analytical Chemistry. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23493&type=Feature&page=1 The color changes of poultry, pork, and smoked salmon following high-pressure processing were studied using the CIE L*, a*, b* system and resonance Raman spectroscopy. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23423&type=Feature&page=1 In situ Raman spectroscopy has been used to probe the chemical composition of the cuticle of a bivalve mollusc to help explain how mussels keep such a strong grip on rocky shorelines. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23147&type=Feature&page=1 Raman spectroscopy can identify samples of an unknown substance at a crime scene as human saliva during forensic analysis, according to a US study, the technique would preserve DNA evidence. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=23173&type=Feature&page=1 Surface-enhanced Raman spectroscopy (SERS) was used for the identification of natural organic dyes belonging to indigoid and anthraquinone classes in archeological samples. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22953&type=Feature&page=1 Fluorescence line-narrowing and resonance Raman properties of various chlorophyll molecules have been measured in organic solvents. The work sheds new light on one of life's most important biochemical processes - photosynthesis - and might one day allow scientists to take another step closer to emulating the reactions to trap solar energy. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22962&type=Feature&page=1 The Raman spectra of 16 lichen specimens from eight genera growing on basaltic lava and wood substrates on new lava fields on the Kilauea volcano, Kona, Hawaii, have been analysed in terms of the pigments and biomolecules produced in this extreme environment. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22810&type=Feature&page=1 The effect of near infrared wavelengths, 785 nm, using both benchtop and portable instrumentation and benchtop 1064 nm on the Raman spectra of seized drugs-of-abuse were compared. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22753&type=Feature&page=1 Bacterial cell walls are a key target for antibiotics but they can change structure during reproduction. Now, Raman spectroscopy and atomic force microscopy have been used to home in on these changes in a bacterium and so provide important clues about the biochemical changes that occur at the cellular level. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22639&type=Feature&page=1 Raman spectral signatures have been obtained for a series of organic minerals using a compact portable Raman instrument, allowing organic minerals to be used as biomarkers for future exobiological missions such as the ESA mission to Mars. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22618&type=Feature&page=1 Nutritionally useful carotenoids and phenolic compounds increase as olives grow but then decrease as they ripen. Now, researchers have demonstrated that monitoring two Raman bands can help growers keep an eye on these changes and so optimise their product for olive oil production. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=6&id=22505&type=Feature&page=1 <p>The board of directors of Thermo Fisher Scientific Inc. has appointed Marc N.
