Available in PDF, EPUB and Kindle. Book excerpt: "By taking it out of its biological role, DNA has served as a robust, reliable and programmable nanofabrication building block for the assembly of a variety of two- and three-dimensional discrete nanometer-sized structures with arbitrary shapes and designs. These molecularly addressable materials could serve as platforms for the site-specific hybridization with nanometer precision. Besides structural complexity, DNA objects evolved to comprise an intrinsic dynamic character allowing them to respond to surrounding stimuli in a predictable manner. Many researchers have previously constructed nanostructures using methods that rely on the spontaneous assembly of DNA in solution, in which case the more complex the assembly design is, the more error-prone the product becomes. This constitutes a major problem for the application of DNA-based structures in dynamic devices such as machines, motors, robots, and computers, where even small errors in assembly can drastically affect performance. Therefore, quantitative tools for analysing structures and dynamics of complex DNA nanostructures are critical. Single molecule fluorescence techniques have been transformative to the field of nanoscience and have played a leading role in providing a mature understanding and an informative feedback on the building blocks and final products of self-assembly. This thesis demonstrates how different single molecule fluorescence methodologies can be utilized to study and advance the structure, dynamics and integrity of DNA-assemblies, specifically those shaped as nanotubes. Conceptually, this research can be divided into four main parts: (i) synthesis optimization, (ii) structural characterization, (iii) monitoring dynamic structures, and (iv) studying structural dynamics. First, a solid-phase synthesis strategy and its visualization through single-molecule spectroscopy was devised to assemble DNA nanotubes in a stepwise fashion, with a full control over their size and sequence pattern. This method paves the way for the production of custom-made DNA nanotubes with fewer structural flaws than the spontaneous-assembly method. Second, single molecule photobleaching and two-color colocalization approaches were uniquely combined to provide a systematic way of assessing the polydispersity, stoichiometry and degree of defectiveness of different DNA nanotubes structures. These approaches will be of significant importance for many research groups synthesizing large supramolecular structures or studying naturally occurring ones, such as protein clusters, amyloids, etc. Third, in situ single molecule immobilization-based fluorescence microscopy was employed to introduce structural changes into DNA nanotubes by dynamically adjusting one or several of the edge lengths between the building blocks using a combination of strand displacement and loops. This is interesting for sensing applications, especially when the analyte produces large scale, detectable structural changes, and also for creating molecular muscles, capable of extension and contraction under external control. Lastly, dynamics and robustness of DNA nanotubes, reconfigured in response to site-specific deletion of DNA strands, were investigated using two color single molecule microscopy. This strategy enables to develop a better understanding of the collective structural changes within DNA structures in response to modifications in their repeat unit. Together, the different methods developed in this thesis underline the importance of single molecule techniques as powerful tools which can advance the field of DNA nanotechnology by enabling the production of well-defined high-quality objects that can meet the designer's compositional and dynamic specifications." --

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the application of wide-field single-molecule fluorescence microscopy techniques to investigations of DNA-surface interactions on chemically graded organosilane surfaces. The adsorption and desorption behaviors of double-stranded (ds) plasmid DNA along the amino-trimethoxysilane and octyl-trichlorosilane gradients were explored as a function of solution pH, solution ionic strength and surface properties. The results provide an improved fundamental understanding of DNA interactions with different surfaces and are certain to aid in the development and advancement of DNA-based biological and biomedical devices. Three distinct experiments were performed in completion of the work for this dissertation. In the first study, total internal reflection fluorescence (TIRF) microscopy was employed to study DNA interactions with aminosilane gradient surfaces under relatively acidic and basic environments. Electrical potentials were applied to assist DNA adsorption and desorption. The single-molecule data clearly showed that DNA capture and release was achieved on the monolayer and submonolayer coated regions of the aminosilane gradient surface under relatively basic pH conditions, with the help of an electrical potential. Meanwhile, DNA adsorption was found to be quasi-reversible on the multilayers at the high aminosilane end of the gradient in the relatively acidic solution. The results of these studies demonstrate the importance of manipulating the electrostatic interactions of DNA with charged surfaces in order to achieve DNA capture and release. The fundamental knowledge of the DNA-surface interactions gained in these studies will be helpful in diverse fields ranging from the layer-by-layer assembly of polyelectrolyte-based thin films to the selective electronic sensing of charged biomolecules. In the second study, the local dielectric properties of the least polar environments in dsDNA were assessed by using the solvatochromic dye, nile red, as a polarity-sensitive probe. TIRF spectroscopic imaging methods were employed in these studies. Although the dielectric constant within the least polar regions of dsDNA was previously predicted by theoretical and computational methods, no experimental measurements of its value had been reported to date. The results provide important knowledge of the factors governing the polarity of DNA microenvironments to which intercalators bind, and provide vital experimental support for the values determined in computational studies. In the third study, TIRF microscopy and single molecule tracking methods were employed to study DNA interactions with an opposed two-component C8-silane and aminosilane gradient surface as a function of solution pH. The mobility of surface-adsorbed DNA molecules was explored and quantified in these studies. The preliminary results further demonstrated the importance of electrostatic interactions over hydrophobic interactions in governing the adsorption of DNA to surfaces. The mobility of surface-adsorbed DNA was found to be largely independent of position along the two-component gradient. These studies were originally undertaken as a route to observation of cooperative effects that are believed to govern DNA-surface binding. Unfortunately, no clear evidence of cooperative effects was observed at the mixed regions of the two-component gradient surface.

Download or read book Genomics of Antibiotic Resistant Bacteria in Industrial Waste Water Treatment written by Maulin P. Shah and published by Springer Nature. This book was released on 2023-11-28 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the key problems and solutions with various applicable approaches to combat antibiotic-resistant genes in industrial waste water. Several genes are selected within the chapters to illustrate the past and future roles of molecular ecophysiology and genomics in the development of wastewater microbiology as an important subdiscipline of microbial ecology. As we have very limited knowledge of composition, dynamics and stability of microbial communities, various processes in wastewater treatment have been generally considered to be "black box." In recent years, with the development of several new high throughput sequencing platforms, metagenome sequencing strategies and bioinformatics toolboxes, the analysis of the genome of complex communities has become much more accessible and means easier. The opening of the biological wastewater treatment “black box” is not the unpleasant experience it was before. The viable, but not cultural, ceases to be the inconsequential, uncharacterizable enigma that existed today. Metagenomics leads the way for more specific studies in related fields. Finally, genomic studies of wastewater treatment microbes, in addition to their biotechnological applications, are also an excellent testing ground for variety of other ecological and environmental burns questions. Wastewater treatment plants are considered hotspots for the environmental dissemination of antimicrobial-resistant determinants. Comparative genomics of antibiotic resistant genes isolated from conventional activated sludge and biological aerated filter wastewater treatment plants is discussed.

Book excerpt: Since Dr. Disiich of Germany prepared a glass lens by the sol-gel method around 1970, sol-gel science and technology has continued to develop. Since then this field has seen remarkable technical developments as well as a broadening of the applications of sol-gel science and technology. There is a growing need for a comprehensive reference that treats both the fundamentals and the applications, and this is the aim of "Handbook of Sol-Gel Science and Technology."The primary purpose of sol-gel science and technology is to produce materials, active and non-active including optical, electronic, chemical, sensor, bio- and structural materials. This means that sol-gel science and technology is related to all kinds of manufacturing industries. Thus Volume 1, "Sol-Gel Processing," is devoted to general aspects of processing. Newly developed materials such as organic-inorganic hybrids, photonic crystals, ferroelectric coatings, photocatalysts will be covered. Topics in this volume include: Volume 2, "Characterization of Sol-Gel Materials and Products, "highlights the important fact that useful materials are only produced when characterization is tied to processing. Furthermore, characterization is essential to the understanding of nanostructured materials, and sol-gel technology is a most important technology in this new field. Since nanomaterials display their functional property based on their nano- and micro-structure, "characterization" is very important. Topics found in Volume 2 include: Sol-gel technology is a versatile technology, making it possible to produce a wide variety of materials and to provide existing substances with novel properties. This technology was applied to producingnovel materials, for example organic-inorganic hybrids, which are quite difficult to make by other fabricating techniques, and it was also applied to producing materials based on high temperature superconducting oxides. "Applications of Sol-Gel Technology," (Volume 3), will cover applications such as:
