Annotation:

Metagenomics approach involves extraction, sequencing and characterization of the genomic content of entire community of microbes present in a given environment. In contrast to genomic data, accurate assembly of metagenomic sequences is a challenging task. Given the huge volume and the diverse taxonomic origin of metagenomic sequences, direct application of single genome assembly methods on metagenomes are likely to not only lead to an immense increase in requirements of computational infrastructure, but also result in the formation of chimeric contigs. A strategy to address the above challenge would be to partition metagenomic sequence datasets into clusters and assemble separately the sequences in individual clusters using any single-genome assembly method. The current study presents such an approach that uses tetranucleotide usage patterns to first represent sequences as points in a three dimensional (3D) space. The 3D space is subsequently partitioned into "Grids". Sequences within overlapping grids are then progressively assembled using any available assembler. We demonstrate the applicability of the current Grid-Assembly method using various categories of assemblers as well as different simulated metagenomic datasets. Validation results indicate that the Grid-Assembly approach helps in improving the overall quality of assembly, in terms of the purity and volume of the assembled contigs.

Annotation:

Elastic fibers consist of two morphologically distinct components: elastin and 10-nm fibrillin-containing microfibrils. During development, the microfibrils form bundles that appear to act as a scaffold for the deposition, orientation, and assembly of tropoelastin monomers into an insoluble elastic fiber. Although microfibrils can assemble independent of elastin, tropoelastin monomers do not assemble without the presence of microfibrils. In the present study, immortalized ciliary body pigmented epithelial (PE) cells were investigated for their potential to serve as a cell culture model for elastic fiber assembly. Northern analysis showed that the PE cells express microfibril proteins but do not express tropoelastin. Immunofluorescence staining and electron microscopy confirmed that the microfibril proteins produced by the PE cells assemble into intact microfibrils. When the PE cells were transfected with a mammalian expression vector containing a bovine tropoelastin cDNA, the cells were found to express and secrete tropoelastin. Immunofluorescence and electron microscopic examination of the transfected PE cells showed the presence of elastic fibers in the matrix. Biochemical analysis of this matrix showed the presence of cross-links that are unique to mature insoluble elastin. Together, these results indicate that the PE cells provide a unique, stable in vitro system in which to study elastic fiber assembly.

The two-dimensional (2D) assembly of the palladium nanoparticles (Pd NPs) was studied in this work. The cubic Pd NPs were successfully synthesized and assembled on mica and silicon wafer in the dip-coating way. The morphology of the Pd NPs and the topography of the Pd NPs assembly on the substrates were characterized with transmission electron microscopy (TEM) and atomic force microscopy (AFM). In the process of the fabrication, the excess cetyltrimethylammonium bromide (CTAB) was removed with the deposition-redispersion strategy, the UV-vis spectra and zeta-potential of the Pd NPs colloid were measured. It was found that the assembly and AFM characterization of the Pd NPs were affected negatively by the presence of excess CTAB. The hydrophilic property of the substrate is the crucial factor to control the 2D assembly of the Pd NPs. Compared with the washed silicon wafer, mica is ultra-hydrophilic and can attract more Pd NPs.

Annotation:

Double-stranded DNA viruses package their genomes into pre-assembled protein procapsids. This process is driven by macromolecular motors that transiently assemble at a unique vertex of the procapsid and utilize homomeric ring ATPases to couple genome encapsidation to ATP hydrolysis. Here, we describe the biochemical and biophysical characterization of the packaging ATPase from Lactococcus lactis phage asccφ28. Size-exclusion chromatography (SEC), analytical ultracentrifugation (AUC), small angle X-ray scattering (SAXS), and negative stain transmission electron microscopy (TEM) indicate that the ~45 kDa protein formed a 443 kDa cylindrical assembly with a maximum dimension of ~155 Å and radius of gyration of ~54 Å. Together with the dimensions of the crystallographic asymmetric unit from preliminary X-ray diffraction experiments, these results indicate that gp11 forms a decameric D5-symmetric complex consisting of two pentameric rings related by 2-fold symmetry. Additional kinetic analysis shows that recombinantly expressed gp11 has ATPase activity comparable to that of functional ATPase rings assembled on procapsids in other genome packaging systems. Hence, gp11 forms rings in solution that likely reflect the fully assembled ATPases in active virus-bound motor complexes. Whereas ATPase functionality in other double-stranded DNA (dsDNA) phage packaging systems requires assembly on viral capsids, the ability to form functional rings in solution imparts gp11 with significant advantages for high-resolution structural studies and rigorous biophysical/biochemical analysis.

ABSTRACT Purified retrovirus Gag proteins or Gag protein fragments are able to assemble into virus-like particles (VLPs) in vitro in the presence of RNA. We have examined the role of nucleic acid and of the NC domain in assembly of VLPs from a Rous sarcoma virus (RSV) Gag protein and have characterized these VLPs using transmission electron microscopy (TEM), scanning TEM (STEM), and cryoelectron microscopy (cryo-EM). RNAs of diverse sizes, single-stranded DNA oligonucleotides as small as 22 nucleotides, double-stranded DNA, and heparin all promoted efficient assembly. The percentages of nucleic acid by mass, in the VLPs varied from 5 to 8%. The mean mass of VLPs, as determined by STEM, was 6.5 × 107 Da for both RNA-containing and DNA oligonucleotide-containing particles, corresponding to a stoichiometry of about 1,200 protein molecules per VLP, slightly lower than the 1,500 Gag molecules estimated previously for infectious RSV. By cryo-EM, the VLPs showed the characteristic morphology of immature retroviruses, with discernible regions of high density corresponding to the two domains of the CA protein. In spherically averaged density distributions, the mean radial distance to the density corresponding to the C-terminal domain of CA was 33 nm, considerably smaller than that of equivalent human immunodeficiency virus type 1 particles. Deletions of the distal portion of NC, including the second Zn-binding motif, had little effect on assembly, but deletions including the charged residues between the two Zn-binding motifs abrogated assembly. Mutation of the cysteine and histidine residues in the first Zn-binding motif to alanine did not affect assembly, but mutation of the basic residues between the two Zn-binding motifs, or of the basic residues in the N-terminal portion of NC, abrogated assembly. Together, these findings establish VLPs as a good model for immature virions and establish a foundation for dissection of the interactions that lead to assembly.

DNA is programmed to hierarchically self-assemble into superstructures spanning from nanometer to micrometer scales. Here, we demonstrate DNA nanosheets assembled out of a rationally designed flexible DNA unit (F-unit), whose shape resembles a Feynman diagram. F-units were designed to self-assemble in two dimensions and to display a high DNA density of hydrophobic moieties. oxDNA simulations confirmed the planarity of the F-unit. DNA nanosheets with a thickness of a single DNA duplex layer and with large coverage (at least 30 μm × 30 μm) were assembled from the liquid phase at the solid/liquid interface, as unambiguously evidenced by atomic force microscopy imaging. Interestingly, single-layer nanodiscs formed in solution at low DNA concentrations. DNA nanosheet superstructures were further assembled at liquid/liquid interfaces, as demonstrated by the fluorescence of a double-stranded DNA intercalator. Moreover, the interfacial mechanical properties of the nanosheet superstructures were measured as a response to temperature changes, demonstrating the control of interfacial shear mechanics based on DNA nanostructure engineering. The rational design of the F-unit, along with the presented results, provide an avenue toward the controlled assembly of reconfigurable/responsive nanosheets and membranes at liquid/liquid interfaces, to be potentially used in the characterization of biomechanical processes and materials transport.

Biocompatible quaternary chitosan/sodium alginate multilayer microcapsules were prepared by layer-by-layer (LBL) self-assembly on the template of monodispersed melamine formaldehyde resin microspheres (MF). The process of self-assembly was monitored by measuring the surface zeta-potential of colloidal particles. The particle size was determined by digital light scattering (DLS) after each deposition, and the average thickness of monolayer film was revealed to be 3.9 nm. Using rhodamine B-labeled quaternary chitosan as the positive polyelectrolyte and sodium alginate as the negative polyelectrolyte, self-assembled multilayer microcapsules with strong red-light emitting were obtained and observed with fluorescence microscope. The fluorescent microcapsules self-assembled from the biocompatible natural polysaccharides may be potentially applied in drug delivery and fluorescence diagnosis.

On-orbit assembly missions typically involve humans-in-the-loop and use large custom-built robotic arms designed to service existing modules. The concept of on-orbit robotic assembly of modularized CubeSat components supports use cases such as rapidly placing failed nodes within a constellation of satellites and monitoring damaged assets in Low Earth Orbit. Despite the recent proliferation of small satellites, there is a lack of planned demonstrations of spacecraft manufactured through the on-orbit assembly as well as the servicing of small satellites in space. Key gaps limiting in-space assembly of small satellites are (1) the lack of standardization of electromechanical CubeSat components for compatibility with commercial robotic assembly hardware, and (2) testing and modifying commercial robotic assembly hardware suitable for small satellite assembly for space operation. Working towards on-orbit robotic assembly, we report on progress addressing both gaps.
Toward gap (1), the lack of standardization of CubeSat components for compatibility with commercial robotic assembly hardware, we have developed a ground-based robotic assembly of a 1U CubeSat using modular components and Commercial-Off-The-Shelf (COTS) robot arms without humans-in-the-loop. Two 16 in x 7 in x 7 in dexterous robot arms, weighing 2 kg each, are shown to work together to grasp and assemble CubeSat components into a 1U CubeSat. We assess performance for a subset of five commercial robotic arm sensors and find the force-torque (FT) sensor as the most efficient sensor for use at the end-effector and brushless motors as the best sensor for use at other joints. We report on the feasibility of sensing and grasping CubeSat components robotically, while using Inverse Kinematics to target, position and maneuver the robot arms.
Addressing gap (2) in this work, solutions for adapting power-efficient COTS robot arms to assemble highly-capable radiation-tolerant CubeSats are examined. We also analyze the systems engineering process for in-space CubeSat robotic assembly systems. Lessons learned on thermal and power considerations for overheated motors and positioning errors were also encountered and resolved. We find that COTS robot arms with sustained throughput and processing efficiency have the potential to be cost-effective for future space missions.

Annotation:

During differentiation, changes in chromatin proteins lead to the establishment and maintenance of gene expression patterns. Histone H3 trimethylated at lysine 4 (H3K4me3) by the trithorax group (trxG) gene family Mixed lineage leukemia (MLL) is associated with active genes. H3K27me3 is trimethylated by the Polycomb group (PcG) Enhancer of Zeste (EZH2) at repressed genes. In Drosophila embryos, trxG and PcG proteins but not H3K4me3 or H3K27me3 are stable to DNA replication. In contrast, methylated histones are detected on nascent DNA in Drosophila and murine cell lines. Therefore some aspect of chromatin assembly or histone trimethylation must differ in different cells. My first aim was to determine if there is a change in the abundance of methylated histones at the replication fork in undifferentiated versus differentiated murine ES cells using two novel in vivo assays. Most undifferentiated ES cells lack early H3K4me3 and H3K27me3, but after 4 days of differentiation, most cells have early trimethylation of H3K4 and H3K27. I propose that the change in kinetics of histone methylation correlates with differentiation. To test this hypothesis, I carried out similar experiments on cells dissociated from day 9.5 (E9.5) and 14.5 (E14.5) murine embryos. In E9.5 cells there are two populations of cells, one that lacks methylated histones and the other contains methylated histones on nascent DNA. By E14.5 most cells exhibit H3K4me3 and H3K27me3 on nascent DNA. To determine if the presence of histone methyltransferases could account for the changes in histone methylation, I tested MLL1 and a subunit of the EZH2 complex, Su(z)12. Both are present continuously on nascent DNA, suggesting that their activity is regulated. Methylation and acetylation antagonize each other at the same residue. However I showed that the presence of acetylated H3K27 is not anticorrelated with H3K27me3 in most murine embryos cells. My results using inhibitors of the appropriate histone acetyltransferase were not conclusive owing to toxicity of the inhibitors. Overall, my results support the hypothesis that trimethylation of H3K4 and H3K27 on nascent DNA is developmentally regulated.

Annotation:

G-Wires are supramolecular DNA structures composing of a quadruplex stem. These structures have been reported to have potential for photo and electrical conductance. However, this has yet to be realized. This thesis is concerned with the rational design of DNA sequences in order to form well-structured G-Wires through optimized self-assembly and characterization of the products. Previous investigation has demonstrated that the quadruplex topology formed from G-rich DNA can be controlled through geometric constraints. These constraints can be imposed through various sequence arrangements which lead to specific structural features. A set of systematically varied DNA sequences were designed to form G-Wire structures. These sequences underwent self-assembly in a range of assembly conditions and the self-assembly products were characterized by a range of techniques such as gel-electrophoresis, NMR, UV-spectroscopy and fluorescence spectroscopy. The findings of this investigation have shown that the rational design of DNA sequences successfully resulted in the formation of architecture with unique optical properties and significantly increased quantum yields. This work has the potential to further the ability of G-Wire structure to be utilized within multicomplex nanodevices in applications such as diagnostic sensing and nanoelectronics.

This study details the dielectrophoretic assembly and mechanical characterization of boron nitride nanotubes on silicon chips with gold electrodes. The chips were fabricated from 4in round silicon wafers with a 100nm-thick low stress silicon nitride insulating layer on the top and bottom. The electrodes were patterned using photo- and electron-beam lithography and dry etching, and the wafers were cut into 4 x 6mm chips. The boron nitride nanotubes studied were obtained from NIA and were synthesized via a unique pressurized vapor/condensor method, which produced long, small-diameter BNNTs without the use of a catalyst. These nanotubes were studied due to their desirable mechanical and electrical properties, which allow for unique applications in various areas of science, engineering, and technology. Applications span from magnetic manipulation to the formation of biocomposites, from nano-transistors to humidity and pH sensors, and from MRI contrast agents to drug delivery. The nanotubes and nanotube bundles characterized were suspended over gaps of 300 to 500nm. This study was unique in that assembly was performed using dielectrophoresis, allowing for batch fabrication of chips and devices. Also, stiffness measurements were performed using AFM, eliminating the reliance of other methods upon electron microscopes, and allowing for imaging and measurements to occur simultaneously and at high resolution. It was found that DEP parameters of V = 2.0Vpp, f = 1kHz, and t = 2min provided the best results for mechanical testing. The nanotubes tested had suspended lengths of 300nm, the width of the electrode gap, and diameters of 15–65nm. Chips were imaged with both scanning electron microscopy and atomic force microscopy. Force-displacement measurements with atomic force microscopy were used to find stiffness values in the range of 1–16N/m. These stiffness values, when plugged into a simple double-clamped beam model, indicated Young’s moduli of approximately 1–1600GPa. Within this wide range, it was shown that a decrease in diameter strongly correlated exponentially to an increase in Young’s modulus. Work in this study was divided between assembly and characterization. Therefore, a lot of time was spent working to optimize dielectrophoresis parameters, followed by SEM and AFM imaging. Parameters that were adjusted included DEP voltage and time, pre-DEP sonication times, as well as adding a centrifuging procedure to attempt to better separate nanotube bundles in solution. Another method discussed but not pursued was the use of surfactants to agitate the solution, thus separating the nanotubes. The reason this material in particular was so difficult to separate was twofold. First, the small size of the nanotubes—individual BNNTs have diameters on the order of ∼5 nanometers—generates very strong nanoscale van der Waals forces holding the nanotubes together. Larger nanotubes—with diameters on the order of 50 to 100nm or more—suffer less from this problem. Also, the dipoles created by the boron-nitrogen bonds cause attraction between adjacent nanotubes. The results shown in this thesis include DEP parameters, SEM and AFM images, and force- displacement curves leading to nanotube stiffness and Young’s modulus values. The force-displacement tests via AFM are also detailed and explained.

Annotation:

The quadruplex formalism describes structural features of unimolecular quadruplex topologies having three loops, described herein as archetypal quadruplexes. The work described here provides a further development of the formalism, based on experimental and conceptual work. Dihedral angles of clockwise and anticlockwise propeller loops were analyzed and found to adopt comparable angles. These loops were also used to define limitations of propeller loop progression, reducing theoretically feasible topologies to 14. Glycosidic bond angle (GBA) conformations throughout the stem for 2, 3-, and 4-stacked versions of each of these 14 topologies have been detailed. Control elements of quadruplex structure have been established, including cation selection, loop length, and loop length relationship to number of stacking tetrads in quadruplex stem. A method to control the design of archetypal G-quadruplexes is proposed, based on rules of precedence. Four atomistic detail solution structures have been derived and structural models deposited in the Protein Data Base: 5J6U, 5J05, 5J4P, 5J4W. Aromatic protons of guanines protruding into grooves of quadruplex structures were evaluated by chemical shift to generate a method of chemical shift indexing. Although currently of limited use, it allows key inferences to be made before sequence-specific assignment of NMR signals, enabling a rapid decision to be reached regarding whether to pursue full structure determination. Investigation of the near-UV region of CD spectropolarimetry enabled derivation of a qualitative method to assess the number of stacking tetrads for two types of stem, representing an improvement on the current CD fingerprint approach to characterize three types of quadruplex stem. Significant steps in deriving the formalism have been made, which describe and predict structural elements of archetypal quadruplexes. These advances represent a major development in understanding of control of G-quadruplex folding. However, they are only one contribution to the advances needed for complete reproducible control of all quadruplex topologies.

Robust manufacturing methods are needed for nanocomponent assembly, and one must understand the physics to optimize the processing and to develop control schemes to deal with the inherent uncertainty. We are studying field induced assembly of a new class of semiconducting metal oxides — nanobelts — that have been demonstrated for chemical sensing. We have demonstrated the integration of nanobelts with electrodes to make sensors by dielectrophoresis (DEP). The SnO2 nanobelts (width ~ 100–300 nm, thickness ~ 30–40 nm) were suspended in ethanol and introduced into a microchannel, and were assembled across the electrodes. Modeling suggests that attraction should occur at all frequencies over this range. Targeted experiments were performed to quantify surface and material properties for input to the modeling, and FEMLAB simulations were performed to validate the model. The goal of the modeling is to optimize the assembly of nanostructures in a manufacturing process at the wafer-scale.

Abstract Recent advancements in additive manufacturing such as Direct Write Inkjet printing introduced novel tools that allow controlled and precise deposition of fluid in nano-liter volumes, enabling fabrication of multiscale structures with submillimeter dimensions. Applications include fabrication of flexible electronics, sensors, and assembly of Micro-Electro-Mechanical Systems (MEMS). Critical challenges remain in the control of fluid deposition parameters during Inkjet printing to meet specific dimensional footprints at the microscale necessary for the assembly process of microscale structures. In this paper we characterize an adhesive deposition printing process with a piezo-electric dispenser of nano-liter volumes. Applications include the controlled delivery of high viscosity Ultraviolet (UV) and thermal curable adhesives for the assembly of the MEMS structures. We applied the Taguchi Design of Experiment (DOE) method to determine an optimal set of process parameters required to minimize the size of adhesive printed features on a silicon substrate with good reliability and repeatability of the deposition process. Experimental results demonstrate repeatable deposition of UV adhesive features with 150 μm diameter on the silicon substrate. Based on the observed wettability effect of adhesive printed onto different substrates we propose a solution for further reduction of the deposit-substrate contact area for microassembly optimization.
