From the self-cleaning properties of the lotus leaf to smartphones that have hundreds of millions times more processing power than computers that sent mankind to the moon, the importance of nanotechnology is beyond dispute. Throughout the last couple of decades, the ever increasing demand for technology have driven not only the quest for new nanomaterials, but also efficient ways to produce them. In this work, novel methods towards producing complex nanomaterials is presented: from molecules to product. In the first part, a method to synthesize quantum dots (QD) from molecular precursors using ultrasound, in an emulsion system under controlled temperature, is presented. This method offers remarkable temporal control, leading to on-demand synthesis of QDs, and has 10x production capacity compared to the typical single-phase sonochemical synthesis of QDs. In the second part, a general bottom-up method to assemble two different kinds of nanoparticles together by engineering the nanoparticle surface is presented, which opens the path towards scalable production of multifunctional nanomaterials. Finally, a specific application of surface engineering and particle assembly is demonstrated in the context of reducing the brittleness of ceramic membranes for energy storage applications.

Gold nanoparticles (AuNPs) with their unique sizes, shapes, and properties have generated much enthusiasm over the last two decades, and have been explored for many potential applications. The successful application of AuNPs depends critically on the ability to modify and functionalize their surface to provide stability, compatibility, and special chemical functionality. This dissertation is aimed at exploring the chemical synthesis and surface modification of AuNPs with the effort to (1) control the number of functional groups on the particle surface, and to (2) increase the colloidal stability at the physiological conditions. To control the functionality on the particle surface, a solid phase place exchange reaction strategy was developed to synthesize the 2 nm AuNPs with a single carboxylic acid group attached on the particle surface. Such monofunctional AuNPs can be treated and used as molecular nanobuilding blocks to form more complex nanomaterials with controllable structures. A "necklace"--Like AuNP/polymer assembly was obtained by conjugating covalently the monofunctional AuNPs with polylysine template, and exhibited an enhanced optical limiting property due to strong electromagnetic interaction between the nanoparticles in close proximity. To improve the colloidal stability in the psychological condition, biocompatible polymers, polyacrylic acid (PAA), and polyethylene glycol (PEG) were used to surface modify the 30 nm citrate-stabilized AuNPs. These polymer-modified AuNPs are able to disperse individually in the high ionic strength solution, and offer as the promising optical probes for bioassay applications. The Prostate specific antigen (PSA) and target DNA can be detected in the low pM range by taking advantages of the large scattering cross section of AuNPs and the high sensitivity of dynamic light scattering (DLS) measurement. In addition to the large scattering cross section, AuNPs can absorb strongly the photon energy at the surface plasmon resonance wavelength and then transform efficiently to the heat energy. The efficient photon-thermal energy conversion property of AuNPs has been used to thermal ablate the A[beta] peptide aggregates under laser irradiation toward Alzheimer's disease therapy.

The concept of nanoarchitechtonics was introduced to describe the correct manipulation of nanoscale materials in the creation of nano-devices and applications. Nanoarchitectonics has begun to spread into many fields including nanostructured materials synthesis, supramolecular assembly, nanoscale structural fabrications, materials hybridizations, materials and structures for energy and environmental sciences, device and physical application, and bio- and medical applications. Following on from the 2012 title Manipulation of Nanoscale Materials, Concepts and Design of Materials Nanoarchitectonics covers the introductory features underlying the field, presenting a unifying overview of the theoretical aspects and emerging applications that are changing the capability to understand and design advanced functional materials. Edited by pioneers of the field, this book will appeal to researchers working in nanoscience, materials science, supramolecular chemistry, physical chemistry and organic chemistry, as well as graduate students in these areas.
