Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes an exploration of interactions between metal nanoparticles and new techniques for their assembly. In Chapter 2, the selfassembly of 300-nm diameter Au, Ag and bimetallic Au-Ag nanowires was studied. Upon deposition onto a glass substrate from suspension in water, the wires self-assembled into densely packed well-ordered arrays. Electrostatic repulsion between the wires was necessary to prevent their aggregation. However, van der Waals forces were a major driving force behind the assembly. This was especially apparent in the assembly of the bimetallic Au-Ag nanowires, which showed a slight non-random preference for orientational ordering. The theoretical simulations of wire assembly at different temperatures strongly indicated that the orientational ordering was driven by the difference in van der Waals attraction between the metals. Chapter 3 describes the temperature-programmed assembly of DNA:Au nanoparticle bioconjugates. In this work, the temperature of the system was manipulated in order to take advantage of temperature-dependent melting properties of the DNA. Despite a 24% loss of DNA from the nanoparticle conjugates and a 14% exchange of DNA sequences between the conjugates when heated, significant control over the order in time of the assembly of multiple DNA:Au conjugate types is demonstrated. This assembly was performed using both sandwich style hybridization systems, in which a half of linking oligonucleotide is hybridized with a DNA sequence on one conjugate type and the other half is hybridized with a sequence on a second conjugate type, as well as with directly complementary hybridization systems. The conjugate types in the resulting assemblies were characterized both by gel electrophoresis and by monitoring the visible absorbance of the conjugate suspensions upon the addition of oligonucleotides complementary to those on the conjugates. In Chapter 4, initial experiments were performed to investigate the feasibility of an on-wire lithography method to fabricate Au nanowires with functionally distinct sides. Conditions for the selective etching of Ni and Ag were determined. The addition of two thiolated DNA sequences, as well as the use of two different DNA attachment chemistries, was explored. Silica-coated Au nanowires with one exposed Au end were synthesized, and Au nanoparticles were electrostatically assembled on the Au end of these wires. The Appendix describes the development of three desktop laboratory experiments for an undergraduate transition metal chemistry course. In a molecular symmetry lab, students used Dots and toothpicks to build molecular models and improve their visualization of symmetry elements. An electronic spectroscopy lab strengthened students' ability to relate ligand field strength and selection rules with the electronic absorption spectra of transition metal complexes. A ligand exchange lab demonstrated the concepts of relative formation constants and the chelate effect. Preliminary assessment to determine the effectiveness of the labs was also performed.

Available in PDF, EPUB and Kindle. Book excerpt: The use of spontaneous self-assembly, as a lithographic tool and as an external field-free means to construct well-ordered and intriguing patterns, has received much attention due to its ease of producing complex, large-scale structures with small feature sizes. An extremely simple route to highly-ordered, complex structures is the evaporative self-assembly of nonvolatile solutes (e.g., polymers, nanoparticles, carbon nanotubes, and DNA) from a sessile droplet on a solid substrate. To date, a few studies have elegantly demonstrated that self-organized nanoscale, microscale, and hierarchically structured patterns have been readily obtained from sophisticated control of droplet evaporation. These include convective assembly in evaporating menisci, the alignment of nanomaterials by programmed dip coating and controlled anisotrophic wetting/dewetting processes, facile microstructuring of functional polymers by the “Breath Figure” method, controlled evaporative self-assembly in confined geometries, etc.This book is unique in this regard in providing a wide spectrum of recent experimental and theoretical advances in evaporative self-assembly techniques. The ability to engineer an evaporative self-assembly process that yields a broad range of complex, well-ordered and intriguing structures with small feature sizes composed of polymers of nanocrystals of different size and shapes as well as DNA over large areas offers tremendous potential for applications in electronics, optoelectronics, photonics, sensors, information processing and data storage devices, nanotechnology, high-throughput drug discovery, chemical detection, combinatorical chemistry, and biotechnology.

Book excerpt: Top-down approaches are currently the main contributor of fabricating microelectronic devices. However, the prohibitive cost of numerous technological steps in these approaches is the main obstacle to further progress. Furthermore, a large number of applications necessitate fabrication of complex and ultra-small devices that cannot be made using these approaches. New approaches based on natural self-assembly of matter need to be developed to allow for fabrication of micro and nanoelectronic devices. Self-assembly of nanostructures is a dynamic field, which explores physics of these structures and new ways to fabricate them. However, the major problem is how to control the properties of the nanostructures resulting from low dimensionality. This book presents recent advances made to address this problem, and fabricate nanostructures using self-assembly.

Available in PDF, EPUB and Kindle. Book excerpt: Polymers provide a useful tool for the controlled assembly of colloidal nanoparticles. We have developed a bricks and mortar" strategy in which colloidal gold particles functionalized with recognition elements serve as the bricks and polymers bearing complementary functionality serve as mortar to hold together the nanoparticles. In this methodology, the conformational flexibility of the polymer compensates for irregularities in the size and shape of the aggregate structure. We have used this method to create discrete micrometer-scale spherical assemblies based on 2 nm gold nanoparticles. Both the size and shape of these assemblies can be controlled, providing spherical assemblies ranging from 50 nm to 1500 nm, as well as network structures.

Available in PDF, EPUB and Kindle. Book excerpt: The ability of nanostructures to organize into complex arrangements leads to unique materials with valuable applications. Self-assembly is therefore a key concept for nanotechnology, but it can be quite a complex and difficult subject to approach. Water Droplets to Nanotechnology gives a simple and general overview of the different self-assembly processes which are at the basis of recent developments in nanotechnology. The book shows how simple phenomenon from everyday examples can become sophisticated tools for self-assembly and the fabrication of nanomaterials. By exploring the coffee stain and tears of wine phenomena, the first part looks at how the evaporation of a droplet of colloidal solution can be used in designing organized structures. This leads onto more complex systems such as templated porous materials, photonic crystals, colloidal nanocrystals and quasi-crystals through to bottom-up systems for designing hierarchal materials. By taking the reader on a journey from everyday life to the secrets of nanotechnology, the book is suitable for a non-specialist audience interested in self-assembly as well as the wider perspectives and latest developments of nanoscience.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is the creation of useful materials, devices, and systems through the control of matter on the nanometer-length scale. This takes place at the scale of atoms, molecules, and supramolecular structures. In the world of chemistry, the rational design of molecular structures and optimized control of self-assembly conditions have enabled us to control the resultant self-assembled morphologies having 1 to 100-nm dimensions with sing- nanometer precision. This current research trend applying the bottom-up approach to molecules remarkably contrasts with the top-down approach in nanotechnology, in which electronic devices are miniaturizing to smaller than 30 nm. However, even engineers working with state-of-the-art computer te- nology state that maintaining the rate of improvement based on Moore’s law will be the most dif?cult challenge in the next decade. On the other hand, the excellent properties and intelligent functions of a variety of natural materials have inspired polymer and organic chemists to tailor their synthetic organic alternatives by extracting the essential structural elements. In particular, one-dimensional structures in nature with sophis- cated hierarchy, such as myelinated axons in neurons, tendon, protein tubes of tubulin, and spider webs, provide intriguing examples of integrated functions and properties. Against this background, supramolecular self-assembly of one-dimensional architectures like ?bers and tubes from amphiphilic molecules, bio-related molecules, and properly designed self-assembling polymer molecules has - tracted rapidly growing interest.

Available in PDF, EPUB and Kindle. Book excerpt: Research in nanostructured materials is motivated by the belief that ability to control the building blocks or nanostructure of the materials can result in enhanced properties at the macroscale: increased hardness, ductility, magnetic coupling, catalytic enhancement, selective absorption, or higher efficiency electronic or optical behavior. Two approaches for the building up of nanoscopic features have been envisaged: top-down and bottom-up. Bottom-up approaches seek to have smaller (usually molecular) components built up into more complex assemblies, while top-down approaches seek to create nanoscale devices by using larger, externally-controlled ones to direct their assembly. This work is mainly dedicated to the self-assembly process of nanoparticles which are synthesized physically or chemically. Our target is to develop new nanoparticle self-assembly process based on the nanoparticles we have synthesized. To further expand our fabrication techniques to engineering applications, we have studied the electrical or optical properties of these nanomaterial structures and we have developed some new chemical sensors out of them.

This book was released on 2012 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembly is a fundamental mechanism by which structures form in materials. This mechanism has given rise to many new technological advances in applications as diverse as structural composites, medicine, alternative energy sources and information technology. Many current approaches to self-assembly have shown promise, but each has its own unique limitations. The over-arching goal of this study is to develop self-assembly processes for nanoparticles that are simple, scalable and cost effective. In this dissertation we examine the mechanism for self assembly of nanoparticles in dispersion and at fluid-fluid interfaces. A simple method is presented for the synthesis of amphiphilic gold nanoparticle surfactants that self-assemble into clusters of controllable structure. The technique is based on the control of particle clustering through sequential functionalization of the surface with thiol terminated polyethylene glycol to sterically stabilize particles in water and short alkane-thiols that render the particles amphiphilic. These nanoparticle surfactants are surface active and form rafts at the air-water interface and stable nanoparticle clusters in dispersion. The clusters are also reminiscent of traditional micelles with an adjustable aggregation number that is controlled via modification of the grafting density of polymer on the nanoparticle surface. The nanoparticle surfactants are also shown to be highly effective emulsifying agents due to their amphiphilicity and they adsorb strongly to oil-water interfaces with controllable inter-particle separation distances. Both the clusters and colloidosomes that can be formed with these particles exhibit tunable shifts in plasmon resonance, enhancing the near-infrared optical absorption and making them useful for a wide range of applications.
