Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Download or read book Nanoscale Assembly written by Wilhelm T.S. Huck and published by Springer Science & Business Media. This book was released on 2006-07-11 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Motion Symmetry Spectroscopy of Chiral Nanostructures written by Johannes Sachs and published by Springer Nature. This book was released on 2022-01-03 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2022-03-04 with total page 2475 pages. Available in PDF, EPUB and Kindle. Book excerpt: World Scientific Reference on Plasmonic Nanomaterials: Principles, Design and Bio-applications is a book collection that encompasses multiple aspects of the exciting and timely field of nanoplasmonics, under the coordination of international plasmonic nanomaterials expert, Dr Luis Liz-Marzán. Plasmonics has a long history, from stained glass in ancient cathedrals, through pioneering investigations by Michael Faraday, all the way into the nanotechnology era, where it blossomed into an extremely active field of research with potential applications in a wide variety of technologies.Given the breadth of the materials, phenomena and applications related to plasmonics, this Reference Set offers a collection of chapters within dedicated volumes, focusing on the description of selected phenomena, with an emphasis in chemistry as an enabling tool for the fabrication of, often sophisticated, plasmonic nanoarchitectures and biomedicine as the target application.Basic principles of surface plasmon resonances are described, as well as those mechanisms related to related phenomena such as surface-enhanced spectroscopies or plasmonic chirality. Under the guidance of theoretical models, wet chemistry methods have been implemented toward the synthesis of a wide variety of nanoparticles with different compositions and tailored morphology. But often the optimal nanoarchitecture requires post-synthesis treatments, including functionalization of nanoparticle surfaces, application of external stimuli toward self-assembly into well-defined supraparticle structures and so-called supercrystals. All such nanomaterials can find applications in various biomedical aspects, most often in relation to diagnosis, through either the detection of disease biomarkers at extremely low concentrations or the design of bioimaging methods for in vivo monitoring. Additionally, novel therapeutic tools can also profit from plasmonic nanomaterials, such as photothermal therapy or nanocatalysis.The reference set thus offers comprehensive information of an extremely active subset within the world of plasmonic nanomaterials and their applications, which aims at not just collecting existing knowledge but also promoting further research and technology transfer into the market and the clinic.
