Available in PDF, EPUB and Kindle. Book excerpt: Deoxyribonucleic acid (DNA), a biopolymer well known for its role in preserving genetic information in biology, is now drawing great deal of interest from material scientists. Ease of synthesis, predictable molecular recognition via Watson-Crick base pairing, vast numbers of available chemical modifications, and intrinsic nanoscale size makes DNA a suitable material for the construction of a plethora of nanostructures that can be used as scaffold to organize functional molecules with nanometer precision. This dissertation focuses on DNA-directed organization of metallic nanoparticles into well-defined, discrete structures and using them to study photonic interaction between fluorophore and metal particle. Presented here are a series of studies toward this goal. First, a novel and robust strategy of DNA functionalized silver nanoparticles (AgNPs) was developed and DNA functionalized AgNPs were employed for the organization of discrete well-defined dimeric and trimeric structures using a DNA triangular origami scaffold. Assembly of 1:1 silver nanoparticle and gold nanoparticle heterodimer has also been demonstrated using the same approach. Next, the triangular origami structures were used to co-assemble gold nanoparticles (AuNPs) and fluorophores to study the distance dependent and nanogap dependencies of the photonic interactions between them. These interactions were found to be consistent with the full electrodynamic simulations. Further, a gold nanorod (AuNR), an anisotropic nanoparticle was assembled into well-defined dimeric structures with predefined inter-rod angles. These dimeric structures exhibited unique optical properties compared to single AuNR that was consistent with the theoretical calculations. Fabrication of otherwise difficult to achieve 1:1 AuNP- AuNR hetero dimer, where the AuNP can be selectively placed at the end-on or side-on positions of anisotropic AuNR has also been shown. Finally, a click chemistry based approach was developed to organize sugar modified DNA on a particular arm of a DNA origami triangle and used them for site-selective immobilization of small AgNPs.

Available in PDF, EPUB and Kindle. Book excerpt: Fueled by a wide range of possibilities to tune their interactions with light, a strong increase of interest could be witnessed in the field of plasmonic nanoparticle research in the recent years. The adjustable size, geometry and spatial arrangement to each other enables to control the optical response of such nanostructures at will. This translates into a plethora of potential applications for medicinal therapy, analytics, catalysis, energy conversion and even for devices with completely artificial optical properties. In order to obtain the building blocks for these materials, strategies to synthesize well-defined particles and their assemblies are required. The present thesis deals with the synthesis and characterization of plasmonic nanoparticles and their assemblies. Rigid-rod linkers based on oligo(phenylene-ethynylenes) could be utilized for the formation of small clusters like nanoparticle dimers. The synthesis of tripodal thioacetates for the preparation of functional SAMs on gold surfaces was performed. Polymer protected gold particles could be synthesized via the Diels-Alder reaction of maleimide@Au particles with a poly(2-vinylpyridine)-block-poly(ethylene oxide) block copolymer bearing a single furan group. Au-PEI and Au-Ag core-shell clusters with tunable optical properties were prepared which could serve as promising building blocks for metamaterials. Block copolymer lithography in combination with a cyclic complexation-reduction approach could be utilized to create ordered plasmonic nanostructures on micrometer surface areas.

Download or read book Design Synthesis and Characterization of Nanoscale Optical Devices Using DNA Directed Self assembly written by William Peter Klein and published by . This book was released on 2016 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Near-field energy transfer has great potential for use in nanoscale communications, biosensing, and light harvesting photonic devices. However, the light collecting and energy transferring efficiency of current devices is poor, resulting in few commercially available applications. Current human-made light harvesting devices lack the benefits of natural selection. Natural systems are typically highly optimized and highly efficient. For example, transfer efficiency in photosynthesis is greater than 90%. In this work, two classes of optical devices were designed, synthesized, and characterized: Plasmonic waveguides and FRET-based photonic devices. In the case of plasmonic waveguides, a multi-scaffold DNA origami synthesis method was developed to fabricate linear waveguides with 10-nm diameter gold nanoparticles. Precise control over interparticle gaps and interchromophore distances was demonstrated. Using a similar approach, DNA labeled fluorophores were arranged in linear and branched geometries to form FRET-based photonic wires and light harvesting devices. Recently, homogeneous FRET (homoFRET) has emerged as a potential way of increasing the transfer efficiency of photonic wires. However, little is known about the design principles needed to construct such devices. To address this knowledge gap, linear photonic wires, and three light harvesting devices were designed, synthesized, and characterized. All the devices contained a homoFRET region to extend the energy transfer distance. Over 50 different FRET-based photonic wires with different homogeneous FRET configurations were evaluated. Several configurations were found that resulted in a higher end-to-end efficiency despite possessing fewer dyes. A six-fold antenna gain was achieved in the case of the light-harvesting devices. The findings demonstrate that homoFRET can be used to increase the energy harvesting capability of photonic devices. In general, the work also showed that DNA nanotechnology can be used to self-assemble a variety of photonic devices. Additionally, the work has established some basic design rules that will enable the bottom-up assembly of more elaborate devices."--Boise State University ScholarWorks.

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.

This book was released on 2020-11-04 with total page 102 pages. Available in PDF, EPUB and Kindle. 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.
