Thorough and up-to-date, this book presents recent developments in this exciting research field. To begin with, the text covers the fabrication of chiral nanomaterials via various synthesis methods, including electron beam lithography, ion beam etching, chemical synthesis and biological DNA directed assembly. This is followed by the relevant theory and reaction mechanisms, with a discussion of the characterization of chiral nanomaterials according to the optical properties of metal nanoparticles, semiconductor nanocrystals, and nanoclusters. The whole is rounded off by a summary of applications in the field of catalysis, sensors, and biomedicine. With its comprehensive yet concise coverage of the whole spectrum of research, this is invaluable reading for senior researchers and entrants to the field of nanoscience and materials science.

Download Chiral Expression at the Nanoscale Origin and Recognition of Chirality Book in PDF, ePub and Kindle
Chirality, familiar to all chemists, is usually applied to molecules or assemblies of molecules and plays an important role in both animate and inanimate systems. It is commonly the case that chirality of a system arises from a chiral building block yet chiral systems can also emerge from achiral units. The objective of this research was to investigate the origin and recognition of chirality at the nanoscale level. To do this, self assembled monolayers made of chirally and achirally tailed molecules were used because such structures are known to form uniform surfaces, which can act as either a source of nucleation or the probing surfaces in chiral recognition. The strategy adopted in the first part of this study was to use chirally modified self assembled monolayers as a source of nucleation for crystallization of achiral compounds that can form either left or right tended forms in chiral crystallization. Such compounds, widely reviewed by Matsura, form chiral crystals even though their building blocks lack a chiral centre. This study presents experiments of induction of chirality in sodium chlorate, hippuric acid and 2,6-ditertbutyl-4-methylphenol crystals. Chiral crystallization of chosen compounds was conducted on D and L cysteine surfaces assembled on gold. The chirality of crystals grown on these surfaces was determined using polarised light microscopy, circular dichroism spectroscopy and NSOM. The small enantiomeric excess achieved in experiments was explained by the limits of chirality determination methods. It was found that crystals formed in enantiomeric excess were of opposite chirality to the SAM they were grown on. This confirms previous results presented by Mastai on crystallization of histidine on cysteine surfaces. The second part of this study presents studies of chiral recognition use of AFM technique-Force Distance Spectroscopy. Chirally and achirally modified SAMs were formed via the Cu-AAC reaction commonly called 'click Chemistry'. This project investigated how the surface preparation influences chiral recognition and if the presence of the second chiral centre affects probing ability. For surface preparation, three types of linkers were used. To functionalize them two complementary compounds equipped with AlaAlaDL and AlaAlaLL dipeptide tail were used. Additional studies were carried out with hippuric acid and glutamic acid-modified SAMs. These studies showed that the way the surface is prepared plays an important role in chiral recognition. In the final recognition experiments it was found that use of molecules possessing either peptide groups or amino acid groups generates additional forces between interacting surfaces, which can be equilibrated by conducting measurements in pH close to their isoelectric point. An influence of the second chiral centre was found for the loosely packed surfaces where the molecules can freely coil.

This book describes the physics behind the optical properties of plasmonic nanostructures focusing on chiral aspects. It explains in detail how the geometry determines chiral near-fields and how to tailor their shape and strength. Electromagnetic fields with strong optical chirality interact strongly with chiral molecules and, therefore, can be used for enhancing the sensitivity of chiroptical spectroscopy techniques. Besides a short review of the latest results in the field of plasmonically enhanced enantiomer discrimination, this book introduces the concept of chiral plasmonic near-field sources for enhanced chiroptical spectroscopy. The discussion of the fundamental properties of these light sources provides the theoretical basis for further optimizations and is of interest for researchers at the intersection of nano-optics, plasmonics and stereochemistry.

Nanotechnology has received tremendous interest over the last decade, not only from the scientific community but also from a business perspective and from the general public. Although nanotechnology is still at the largely unexplored frontier of science, it has the potential for extremely exciting technological innovations that will have an enormous impact on areas as diverse as information technology, medicine, energy supply and probably many others. The miniturization of devices and structures will impact the speed of devices and information storage capacity. More importantly, though, nanotechnology should lead to completely new functional devices as nanostructures have fundamentally different physical properties that are governed by quantum effects. When nanometer sized features are fabricated in materials that are currently used in electronic, magnetic, and optical applications, quantum behavior will lead to a set of unprecedented properties. The interactions of nanostructures with biological materials are largely unexplored. Future work in this direction should yield enabling technologies that allows the study and direct manipulation of biological processes at the (sub) cellular level.

Download Colloidal Synthesis of Plasmonic Nanometals Book in PDF, ePub and Kindle
Noble metal nanoparticles have attracted enormous scientific and technological interest because of their unique optical properties, which are related to surface plasmon resonances. The interest in nanosized metal particles dates back to ancient societies, when metals were used in various forms as decorative elements. From the famous Lycurgus cup, made by the Romans in the 4th century AD, through thousands of stained glasses in churches and cathedrals all over medieval Europe, bright-yellow, green, or red colors have been obtained by a touch of metallic additions during glass blowing. This peculiar interaction of light with nanometals can be widely tuned through the morphology and assembly of nanoparticles, thereby expanding the range of potential applications, from energy and information storage to biomedicine, including novel diagnostic and therapeutic methods. This book compiles recent developments that clearly illustrate the state of the art in this cutting-edge research field. It comprises different review articles written by the teams of Prof. Luis Liz-Marzán, an international leader in chemical nanotechnology who has made seminal contributions to the use of colloid chemistry methods to understand and tailor the growth of metal particles at the nanoscale. Apart from synthesis, the book also describes in detail the plasmonic properties of nanomaterials and illustrates some representative applications. This book will appeal to anyone involved in nanotechnology, nanocrystal growth, nanoplasmonics, and surface-enhanced spectroscopies.
