Surface Enhanced Vibrational Spectroscopy (SEVS) has reachedmaturity as an analytical technique, but until now there has beenno single work that describes the theory and experiments of SEVS.This book combines the two important techniques of surface-enhancedRaman scattering (SERS) and surface-enhanced infrared (SEIR) intoone text that serves as the definitive resource on SEVS.* Discusses both the theory and the applications of SEVS andprovides an up-to-date study of the state of the art* Offers interpretations of SEVS spectra for practicinganalysts* Discusses interpretation of SEVS spectra, which can often bevery different to the non-enhanced spectrum - aids the practicinganalyst

Developing innovative efficient and sensitive spectroscopic and optical techniques for studying biomedically relevant molecules, structures and processes in vitro and in vivo is a field of rapidly growing interest. This symposium book covers novel and exciting approaches in biomedical spectroscopy. Several chapters deal with infrared and Raman spectroscopy. These complimentary vibrational spectroscopic techniques are capable of monitoring molecular structures as wellas structural changes. Such studies are of interest for understanding diseases at a molecular level as well as for developing techniques for efficient early diagnosis based on molecular structural information. The chapters demonstrate also applications vibrational spectroscopy in proteomics and thecharacterization of micro organisms. The second section of the book introduces surface enhanced Raman scattering (SERS), demonstrates the application of the effect in the biomedical field and develops the concept of multifunctional nanosensors. The measurement of intrinsic optical signals from biological objects such as nerve tissue are discussed in the next section of the book. Chapters deal also with Coherent anti-Stokes Raman scattering (CARS) and fluorescence fluctuation spectroscopy.Other chapters illustrate how photons of very different energies, in the Terahertz and in the ultra violet range, can be used to retrieve molecular structural information from native biomolecules. The electrical properties of protein molecules adsorbed onto a gold substrate are studied by using ascanning Kelvin nanoprobe in a microarray format. The final chapters in the book demonstrate the powerful combination of different spectroscopic techniques for the characterization of biomolecules as well as native and engineered biomaterials. These chapters combine information from Raman and Inelastic Neutron Scattering, optical absorbance and energy dispersive X-ray analysis, positron annihilation lifetime spectroscopy (PALS), 1H NMR, and 129Xe NMR X-ray diffraction and fluorescenceresonance energy transfer.

A comprehensive presentation of Surface-Enhanced Raman Scattering (SERS) theory, substrate fabrication, applications of SERS to biosystems, chemical analysis, sensing and fundamental innovation through experimentation. Written by internationally recognized editors and contributors. Relevant to all those within the scientific community dealing with Raman Spectroscopy, i.e. physicists, chemists, biologists, material scientists, physicians and biomedical scientists. SERS applications are widely expanding and the technology is now used in the field of nanotechnologies, applications to biosystems, nonosensors, nanoimaging and nanoscience.

This book provides a comprehensive overview of the multiple strategies that plants have developed to cope with drought, one of the most severe environmental stresses. Experts in the field present 17 chapters, each of which focuses on a basic concept as well as the latest findings. The following major aspects are covered in the book:·       Morphological and anatomical adaptations·       Physiological responses·       Biochemical and molecular responses·       Ecophysiological responses·       Responses to drought under field conditionsThe contributions will serve as an invaluable source of information for researchers and advanced students in the fields of plant sciences, agriculture, ecophysiology, biochemistry and molecular biology.

This Soil Biology volume examines our current understanding of the mechanisms involved in the beneficial effects transferred to plants by endophytes such as rhizobial, actinorhizal, arbuscular mycorrhizal symbionts and yeasts. Topics presented include how symbiosis starts on the molecular level; chemical signaling in mycorrhizal symbiosis; genomic and functional diversity of endophytes; nitrogen fixation; nutrient uptake and cycling; as well as plant protection against various stress conditions. Further, the use of beneficial microorganisms as biopesticides is discussed, particularly the application of Plant Growth Promoter Rhizobacteria (PGPR) in agriculture with the aim to increase yields.
