Publication date: Available online 18 September 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Amane Shiohara , Yusong Wang , Luis M. Liz-Marzán Surface enhanced Raman scattering (SERS) spectroscopy is a powerful technique that provides molecular information through greatly enhanced Raman scattering from minute amounts of substance near nanostructured metallic surfaces. SERS is thus a promising technique for ultrasensitive sensing applications. Plasmonic nanostructures including metal nanoparticles and lithographically prepared nanostructures are ideal substrates to prod...

Recent Advances in Photosynthetic Energy Conversion
Publication date: Available online 21 September 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Narendran Sekar , Ramaraja P. Ramasamy Photosynthesis is one of the first natural processes evolved by cyanobacteria, algae and green plants to trap light and CO2 in the form of reduced carbon compounds while simultaneously oxidizing water to oxygen. The photosynthetic energy conversion forms the basis for all the existing life today. The photosynthetic energy is being harnessed in many ways using modern technologies for the production of fuels using photosynthetic organisms, gen...

Surface enhanced Raman spectroscopy (SERS): Potential applications for disease detection and treatment
Publication date: Available online 21 September 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Sarah McAughtrie , Karen Faulds , Duncan Graham The implementation of Raman and surface enhanced Raman spectroscopy (SERS) for the detection of disease has increased in recent years. The reasons for their increased implementation have often been attributed to their well-known advantages, including the production of narrow spectral bands, which are characteristic of the molecular components present, their non-destructive method of analysis and the sensitivity and specificity whic...

Potential applications of porphyrins in photodynamic inactivation beyond the medical scope
Publication date: Available online 21 September 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Eliana Alves , Maria A.F. Faustino , Maria G.P.M.S. Neves , Ângela Cunha , Helena Nadais , Adelaide Almeida Although the discovery of light-activated antimicrobial agents was reported in the 1900s, only more recently research work has been developed towards the use of photodynamic process as an alternative to more conventional methods of inactivation of micro(organisms). The photoprocess causes cell death through irreversible oxidative damage by reactive oxygen species produ...

Thermodynamic vs. Kinetic Control of Excited-State Proton Transfer Reactions
Publication date: Available online 2 October 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Vladimir I. Tomin , Alexander P. Demchenko , Pi-Tai Chou The “Excited-State Intramolecular Proton Transfer” (ESIPT) reactions in a number of organic fluorophores are among the fastest basic chemical reactions known so far and their rates can be observed even on femtosecond time scale. Accordingly, the reactant, as monitored by its emission, should be negligibly small. In sharp contrast to this conventional wisdom, however, the coexistence of the reactant and the product of this...

The Simplest Plasmonic Molecules: Metal Nanoparticle Dimers and Trimers
Publication date: Available online 18 October 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Nir Zohar , Lev Chuntonov , Gilad Haran This review discusses research on the plasmonic properties of small clusters of metal nanoparticles, with two and three particles. These are the simplest examples of ‘plasmonic molecules’. Coupling between two particles leads to new surface plasmon resonances and to the creation of a hot spot of a strong electric field in the gap between the particles. Such a hot spot can be used to enhance Raman scattering or fluorescence, making plasmo...

Recent progress and frontiers in the electromagnetic mechanism of surface-enhanced Raman scattering
Publication date: Available online 18 October 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Yuko S. Yamamoto , Yukihiro Ozaki , Tamitake Itoh The electromagnetic (EM) enhancement of the optical responses of molecules close to plasmonic metal nanostructures has been applied for ultra-sensitive detection in vibrational spectroscopy. Recently, the research fields of EM enhancement entered a new regime wherein the enhancement effects are connected to photochemical and photobiological phenomena. For this regime, the conventional theorem used to understand the EM enhancement e...

Influence of oxygen nonstoichiometry and doping with 2p-,3p-, 6p- and 3d- elements on electronic structure,optical properties and photocatalytic activity of rutile and anatase:ab initio approaches.
Publication date: Available online 30 October 2014 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): V.M. Zainullina , V.P. Zhukov , M.A. Korotin Among wide-energy-gap semiconductors, doped titanium dioxides (anatase or/and rutile polymorphs) are the most promising materials for designing photocatalysts active in the visible region of solar spectrum, for photodegradation of organic molecules and for photolysis of water. It has been established recently that doping of titanium dioxides with 2p-, 3p-, 6p- and 3d-elements significantly increases their photocatalytic activity. In thi...
