Results show that overt infection and biofilm formation might be better avoided using the funnel technique to avoid contamination. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26657&type=Feature&page=1 Ultraviolet absorption at 254 nm and the intensities of fluorescence peaks corresponding to humic, fulvic and protein-like material were evaluated to assess dissolved organic carbon (DOC) removal during coagulation-flocculation. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26596&type=Feature&page=1 A water-quality system based on multiple sensors, UV-Vis spectroscopy, and turbidity measurements can be used to monitor waste water from restaurants and other sites. Writing in the journal Water Research, the developing team offers a case study as proof of principle. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26476&type=Feature&page=1 Two related triphenylamine-based dipolar and octupolar fluorophores were used to prepare aqueous suspensions of fluorescent organic nanoparticles exhibiting extremely high one- and two-photon brightness, superior to those obtained for quantum dots. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26434&type=Feature&page=1 Galaxies recycle immense volumes of hydrogen gas and heavy elements. In so doing they help to build successive generations of stars in processes that stretch out across billions of years, according to data obtained using the ultraviolet-sensitive Cosmic Origins Spectrograph. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26348&type=Feature&page=1 The first in vivo measurements of oxygen saturation in the walls of human bladders with normal function have been reported as proof of principle for using this marker to explore bladder dysfunction. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26320&type=Feature&page=1 Ultraviolet spectroscopy, as well as NMR and mass spectrometry, have been used by an Austrian team to reveal the existence of a previously unknown chlorophyll decomposition product in the autumn leaves of Norway maples. The novel structure suggests an entirely different degradation route not seen in other deciduous trees is present. The work suggests that the route is more akin to the formation of bile pigment from broken down haemoglobin. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26243&type=Feature&page=1 A process has been described for the fabrication of photoluminescent nanopillars by replication from nanoporous anodic alumina via template wetting using polymer from different chemical families. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26204&type=Feature&page=1 A whole raft of techniques, including UV-Vis spectroscopy has been used to characterise systematically biological composites containing silver-nanocrystals produced by the fungus Cylindrocladium floridanum in a novel, environmentally benign biological process. The biocomposite can rapidly degrade the widespread toxic pollutant nitrophenol. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26071&type=Feature&page=1 Problems with crosstalk in dual-color fluorescence correlation spectroscopy studies of protein interactions in living cells have been overcome with an approach based on fluorescence lifetime correlation spectroscopy. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=26057&type=Feature&page=1 A collaboration between teams in Germany and the US has shown that one of the building blocks of the nucleic acids DNA and RNA, adenine, has a previously unrecognised variable range of ionization energies along its reaction pathways. The finding could improve our understanding of experimental data regarding how adenine survives exposure to ultraviolet light, showing that the processes might be more complicated than previously thought. However, it also has potentially far-reaching implications for spectroscopic measurements of other heterocyclic compounds. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25998&type=Feature&page=1 Image analysis methods are presented for the detection and classification of single molecules and single-molecule interactions detected using padlock probes or proximity ligation. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25949&type=Feature&page=1 Researchers who have been working for nearly a decade to piece together the process by which an enzyme repairs UV-damaged DNA have finally witnessed the entire process in full detail in the laboratory and it seems just one electron underpins the whole process pointing to a potential treatment for sunburn. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25849&type=Feature&page=1 Synchronous fluorescence spectroscopy was evaluated as a new tool for real-time bioprocess monitoring of animal cell cultures using bioreactor cultures of three monoclonal antibody-producing CHO cell lines. The technique provides data on various fluorescent compounds in a single spectrum, showing improved peak resolution and recording speed. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25785&type=Feature&page=1 Discriminating between original documents produced using an inkjet printer is now much easier and could be used in forensic analysis to spot forgeries and counterfeit documents through the coupling of micellar electrophoretic capillary chromatography (MECC) and UV-Vis spectroscopic data. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25716&type=Feature&page=1 The diagnostic potential of optical spectroscopy in peri-implant inflammation in vivo was evaluated by assessing multiple inflammatory parameters (tissue oxygenation, total tissue hemoglobin, deoxyhemoglobin, oxygenated hemoglobin and tissue edema) simultaneously. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25580&type=Feature&page=1 UV-Vis spectroscopy and various other techniques have been used to analyse the yellow pigments found in Mayan wall paintings. The compouns present are the indigoids, including isatin and dehydroindigo. The spectra together with SEM/EDX, TEM and voltammetry of microparticles show that this ancient people had the recipe for making indigo itself and converting it to Maya Blue and Maya Yellow in a stepwise reaction sequence. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25458&type=Feature&page=1 Fluorescence spectroscopy has been used to identify the range and maxima of excitation and emission spectra of colliodal cadmium sulfide quantum dots capped with dioctyl sulfosuccinate, deposited upon substrates of gold, mica and gallium arsenide. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25360&type=Feature&page=1 Atmospheric and climate models may have overlooked the fact that exactly how clouds appear to reduce the amount of sunlight available for warming the surface of the earth depends on the wavelength being measured across the spectrum from infrared to ultraviolet. The finding could now help researchers improve climate models by factoring in the effects of cloud cover more precisely. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=7&id=25276&type=Feature&page=1 An effective classification algorithm was derived for optical spectroscopy as an adjunct to colposcopy and preliminary estimates of its accuracy were obtained for the detection of cervical intraepithelial neoplasia or worse.
