Translational Orientational And Spectral Dynamics Of Individual Molecules In Nano Structured Materials Studied With Single Molecule Spectroscopy

Single-molecule studies constitute a distinguishable category of focused - search in nanoscience and nanotechnology. This book is dedicated to the - troduction of recent advances on single-molecule studies. It will be illustrated that studying single molecules is both intellectually and technologically ch- lenging, and also o?ers vast potential in opening up new scienti?c frontiers. We wish to present the readers with several di?erent techniques for studying single molecules, such as electron-tunneling methods, interaction-force m- surement techniques, optical spectroscopy, plus a number of directions where further progress could be pursued. We hope the work may assist the readers, especially graduate students and those who wish to explore single molecules, to become familiarized with the pace of the progress in this ?eld and the relevant primary techniques. Due to limitation of space, we are not able to elaborate on the technical details of all of the experimental methods that are vital in single molecule studies, so introductions to only selected experimental methods are touched in the context. Since the technical details and theoretical analysis of these techniqueshavealreadybeenthoroughlycoveredinmanyliteratures,weonly provide introductions to the basic principles of the detection techniques here, and focus on their experimental achievements in the area of single-molecule studies. These techniques have proven to be highly e?ective when indep- dently used. The combinationof those techniques could lead to further - vances in the detection capabilities.

This book focuses on recent advances in the rapidly evolving field of single molecule research. These advances are of importance for the investigation of biopolymers and cellular biochemical reactions, and are essential to the development of quantitative biology. Written by leading experts in the field, the articles cover a broad range of topics, including quantum photonics of organic dyes and inorganic nanoparticles and monitoring of single molecule (enzymatic) reactions.

From artificial surfaces to living cells, Molecular Nano Dynamics, Vol. I and Vol. II explores more than 40 important methods for dynamic observation of the nanoscale. Edited by absolute science greats from Japan, this two-volume set covers all important aspects of this topic: nanoscale spectroscopy and characterization tools, nanostructure dynamics, single living cell dynamics, active surfaces, and single crystals. Destined to be the definitive reference work on nanoscale molecular dynamics and their observation for years to come, this is a must-have reference for chemists, physicists, physical chemists, theoretical chemists, and materials scientists.

This thesis presents a novel single-molecule spectroscopy method that, for the first time, allows the dipole orientations and fluorescence lifetimes of individual molecules to be measured simultaneously. These two parameters are needed to determine the position of individual molecules with nanometer accuracy near a metallic structure. Proof-of-principle experiments demonstrating the value of this new single-molecule localization concept are also presented. Lastly, the book highlights potential applications of the method in biophysics, molecular physics, soft matter and structural biology.

This book focuses on complex shaped micro- and nanostructures for future biomedical and sensing applications that were investigated by both theory and experiments. The first part of the book explores rotation-translation coupling of artificial microswimmers at low Reynolds numbers. Usually corkscrew shapes, i.e chiral shapes, are considered in such experiments, due to their inspiration from nature. However, the analysis of the relevant symmetries shows that achiral objects can also be propulsive, which is experimentally demonstrated for the first time. In the second part, a new single-particle spectroscopy technique was developed and the role of symmetry in such measurements is carefully examined. Spectra stemming from one individual nanoparticle that is moving freely in bulk solution, away from a surface, and only due to Brownian motion, are presented. On that basis, the rotationally averaged chiroptical spectrum of a single nanoparticle is measured - a novel observable that has not been accessible before.

Ultrafast Dynamics at the Nanoscale provides a combined experimental and theoretical insight into the molecular-level investigation of light-induced quantum processes in biological systems and nanostructured (bio)assemblies. Topics include DNA photostability and repair, photoactive proteins, biological and artificial light-harvesting systems, plasmonic nanostructures, and organic photovoltaic materials, whose common denominator is the key importance of ultrafast quantum effects at the border between the molecular scale and the nanoscale. The functionality and control of these systems have been under intense investigation in recent years in view of developing a detailed understanding of ultrafast nanoscale energy and charge transfer, as well as fostering novel technologies based on sustainable energy resources. Both experiment and theory have made big strides toward meeting the challenge of these truly complex systems. This book, thus, introduces the reader to cutting-edge developments in ultrafast nonlinear optical spectroscopies and the quantum dynamical simulation of the observed dynamics, including direct simulations of two-dimensional optical experiments. Taken together, these techniques attempt to elucidate whether the quantum coherent nature of ultrafast events enhances the efficiency of the relevant processes and where the quantum–classical boundary sets in, in these high-dimensional biological and material systems. The chapters contain well-illustrated accounts of the authors’ research work, including didactic introductory material, and address a multidisciplinary audience from chemistry, physics, biology, and materials sciences. The book is, therefore, a must-have for graduate- and postgraduate-level researchers who wish to learn about molecular nanoscience from a combined spectroscopic and theoretical viewpoint.

The development of nanostructured materials represents a new and fast evolving application of recent research in physics and chemistry. Novel experimental tools coupled with new theory have made this possible. Topics covered in this book include nanocrystals, semiconductor heterostructures, nanotubes, nanowires, and manipulation and fabrication tec

"Rapid advances in chemical synthesis and fabrication techniques have led to novel nano-sized materials that exhibit original and often unforeseen properties. One of the greatest advantages of these nano-systems is that their electronic and optical properties can be controlled, not only by the material's inherent features, but also by the sample's size, shape, and topology. This flexibility makes them ideal for applications in several fields, ranging from electronics and optoelectronics to biology and medicine. However, in order to design nanoelectronic devices, a clear understanding of their fundamental properties is needed. Semiconductor quantum dots (QDs) and single-walled carbon nanotubes (SWCNTs) are two of the most promising examples of low-dimensional nanomaterials. These two types of nano-systems have been chosen for the extensive studies presented in this book." --Book Jacket.
