Technology today is directed towards building smaller devices. To accommodate this development, printing methods are needed. Some printing methods that are used include lithography, micro-contact printing, and inkjet printing. These methods all require specialized instrumentation, hazardous chemicals, and complicated and tedious steps that increase cost of manufacturing. Nano-contact printing is an alternative solution which relies on the specificity of DNA to direct molecules into precise patterns. This study attempts to find the limitations of nano-contact printing through the printing of oligonucleotide monolayers. Eight pattern transfers were made with one master copy and the oligonucleotide surface coverage was analyzed using tapping mode atomic force microscopy (AFM). The percent coverage of oligonucleotide was then calculated from the tapping mode AFM phase images. Two general trends were found. The oligonucleotide surface coverage on the master increased slightly, while the surface coverage on the pattern transfers decreased. One possible explanation for the trends is that the decrease in contact between master and secondary substrate is due to both the accumulation of dirt and the wear and tear of' the master. By improving the contact between master and secondary substrate, the printing method can be expanded from printing monolayers to high resolution patterns.

Pełny tekst źródłaThe quest to achieve ultrahigh sensitivity, surface specificity and high spatial resolution has led to the development of plasmon- and chemically- enhanced Raman spectroscopy, including techniques such as surface-enhanced Raman spectroscopy (SERS) and tip-enhanced Raman spectroscopy (TERS). However, a lack of fundamentally experimental demonstrations still remains. In this thesis, I firstly used gap-mode TERS, which allows studying even molecularly thin layers of very weakly scattering molecules. With the nanoscale spatial resolution provided by TERS, the spontaneous segregation in a mixed thiol system on a gold surface could be resolved, while scanning tunneling microscopy (STM) could not discern the nanodomains via their apparent height difference. Furthermore, since graphene and a flat gold surface both were known to provide some Raman enhancement through mainly a chemical mechanism, sandwiching copper phthalocyanine (CuPc) molecules between graphene and a flat gold surface allowed electrons to be transferred in both directions, and thereby to address the question whether chemical enhancements with different origins in SERS can add to each other. The results suggest that the chemical enhancements were influenced by the two individual surfaces, and a 68-fold enhancement of sandwiched CuPc between graphene and gold was observed, as compared to CuPc on mica. Last, TERS was applied to study this sandwiched structure. Molecules self-assembled on a gold surface and covered by transferred graphene acted as optical probes. Such an arrangement has interesting properties in the sense that molecules are protected and encapsulated by graphene. Also, a possible ultrahigh Raman enhancement together with localized spatial resolution may be achieved due to the combined effects from SERS and TERS. The results showed that a tip can improve graphene-enhanced Raman scattering (GERS) further by 4 orders of magnitude, but graphene exerts some shielding effect to gap-mode TERS.

Pełny tekst źródłaGranular crystals are spatially periodic structures of elastic particles arranged in crystal lattices. The interactions between particles take place via their elastic interconnections, which are of much smaller dimensions and weights than the beads. This induces propagation of elastic waves in granular structures at significantly slower velocities than in the individual grains. In addition, due to the existence of non-central shear forces, rotations of particles can be initiated, leading to extra phononic modes in the crystals. In the manuscript, wave dynamics in two-dimensional monolayer granular crystals with either out-of-plane or in-plane particle motion is studied. The phononic properties are investigated, including Dirac points, zero-frequency modes, zero-group-velocity modes and their transformation into slow propagating phononic modes. Furthermore, in the presence of edges/boundaries, zero-frequency and extremely slow elastic edge waves can be also predicted in mechanical granular honeycomb crystals (granular graphene). In addition, topological properties of rotational edge waves in a granular graphene are theoretically demonstrated. By inducing topological transition, which turns the topological order of granular graphene from trivial to nontrivial, topological edge transport in the granular graphene can be observed. The developed theories could promote the potential applications of designed granular structures with novel elastic wave propagation properties

Pełny tekst źródłaSurface modification is of paramount importance in many fields of chemistry like analytical chemistry and molecular electronics. This work deals with the study of different monolayers covalently bound on conducting (mainly carbon) surfaces, and produced from the electroreduction of aryldiazonium salts. By introducing electroactive components in the resulting monolayers, the different studies in this work mainly focused on charge-transfer properties (in a large sense). First, monolayers bearing simple redox-active ferrocenyl terminal groups were investigated. The electrochemical behavior of these monolayers was analyzed in different conventional organic media and in ionic liquids (RTILs) and by varying the length of the bridging unit between the surface and the ferrocene groups. Second, redox-active tetrathiafulvalene (TTF) molecules were used to functionalize the monolayers. TTF molecules are well-known donor molecules able to form charge-transfer complexes with tetracyanoquinodimethane (TCNQ) as an electron-acceptor. The formation of charge-transfer complexes between immobilized TTF and TCNQ derivatives was studied and modulated by varying the chain length of the bridging unit between the TTF donor and the surface and by varying the electron-withdrawing ability of the TCNQ acceptors. Third, monolayers with fluorene and spirobifluorene (SBF) terminal groups were prepared. The blocking behavior towards electron transfer was studied by electrochemical microscopy (SECM) with two redox mediators and the conductivity of the layers was investigated by CP-AFM (Conducting Probe-Atomic Force Microscopy). Effects due to the steric hindrance of the fluorene or SBF derivatives were evidenced. Such stable, organized and organic monolayers seem to be promising candidates for molecular electronic devices

Pełny tekst źródłaLos dicalcogenuros de metal de transición (TMD) monocapa suspendidos combinan una masa ultrabaja y propiedades ópticas excepcionales, lo que los convierte en materiales intrigantes para aplicaciones opto-mecánicas. Sin embargo, el bajo factor de calidad Q medido en los resonadores de TMD ha sido un obstáculo hasta ahora. En esta tesis, primero mostramos una lectura óptica ultra sensible de resonadores TMD de monocapa que nos permite revelar sus propiedades mecánicas a temperaturas criogénicas. Encontramos que el factor de calidad de los resonadores WSe2 monocapa aumenta considerablemente por debajo de la temperatura ambiente, alcanzando valores tan altos como 1.6 x 104 en temperatura de nitrógeno líquido y 4.7 x 104 en temperatura de helio líquido. Esto supera el factor de calidad de los resonadores de grafeno monocapa con áreas de superficie similares. Al enfriar el resonador, la frecuencia de resonancia aumenta significativamente debido a la contracción térmica la red del cristal de WSe2. Estas mediciones nos permiten estudiar experimentalmente el coeficiente de expansión térmica de las monocapas de WSe2 por primera vez. Los altos factores Q también se encuentran en los resonadores basados en las monocapas de MoS2 y MoSe2. El alto factor de calidad que se encuentra en este trabajo abre nuevas posibilidades para acoplar estados vibracionales mecánicos a excitones bidimensionales, valley pseudo-spins y emisores cuánticos únicos y para experimentos opto-mecánicos cuánticos basados en la interacción de Casimir. Las capacidades de detección ofrecidas por este nano-resonador mecánico de alto factor Q también son interesantes para estudiar propiedades termodinámicas en regímenes de la materia condensada a los que es difícil acceder. En la segunda parte de la tesis, utilizamos sistemas optomecánicos basados en una monocapa de MoSe2 para probar las propiedades térmicas de los fonones en redes de cristales bidimensionales. Medimos la conductividad térmica y la capacidad calorífica específica hasta temperaturas criogénicas. Los régimenes de transporte de fonones pasan de el difuso al balístico al bajar la temperatura por debajo de 100 K. La dependencia de la temperatura de la capacidad calorífica específica se aproxima a una dependencia cuadrática, lo cual es la firma de las redes bidimensionales. Tanto la conductividad térmica como las mediciones de la capacidad calorífica específica son coherentes con las predicciones basadas en primeros principios. Nuestro resultado establece una nueva estrategia para investigar el transporte térmico en materiales bidimensionales y permite explorar el régimen hidrodinámico de fonones, la conducción de calor anómala y las transiciones de fase de los fenómenos colectivos de cuerpos electrónicos en monocapas.

Pełny tekst źródłaThe study and understanding of molecular interactions is fundamentally important in today's field of life sciences and there is a demand for well designed surfaces for biosensor applications. The biosensor has to be able to detect specific molecular interactions, while non-specific binding of other substances to the sensor surface should be kept to a minimum. The objective of this master´s thesis was to design sensor surfaces based on self-assembled monolayers (SAMs) and evaluate their structural characteristics as well as their performance in Biacore systems. By mixing different oligo (ethylene glycol) terminated thiol compounds in the SAMs, the density of functional groups for bimolecular attachment could be controlled. Structural characteristics of the SAMs were studied using Ellipsometry, Contact Angle Goniometry, IRAS and XPS. Surfaces showing promising results were examined further with Surface Plasmon Resonance in Biacore instruments.
Mixed SAM surfaces with a tailored degree of functional COOH groups could be prepared. The surfaces showed promising characteristics in terms of stability, immobilization capacity of biomolecules, non-specific binding and kinetic assay performance, while further work needs to be dedicated to the improvement of their storage stability. In conclusion, the SAM based sensor surfaces studied in this thesis are interesting candidates for Biacore applications.

Pełny tekst źródłaThis characteristic electrochemical property of FcC12S-Au system allows for the quantification of defects in SAMs. This is important because coverage defects, or voids in alkylthiol SAMs, are a critical component of electron transfer mechanisms of soluble redox probes. Short time exposure of a defective SAM to FcC12SH leads to a quantifiable defect-related Fc coverage (GammaFc), with GammaFc < 1% being readily measurable. Using FcC12SH as a label, a number of alkylthiol SAM preparation conditions have been assessed.
FcC12SH is further used to probe the progress of the important alkylthiol-for-alkylthiol exchange reaction in SAMs. It is shown that variation of chain length, reaction temperature, terminal group, applied potential, and the initial defect density determines the extent and the rate of the exchange reaction. Kinetics studies of binary (FcC12S-/CH3RS-Au) SAM formation via co-incubation reveal that although csurfFc is initially close to the solution mole fraction of the FcC12 SH ( csolnFc ), the subsequent exchange reaction leads to a csurfFc which is often quite different from csolnFc .
Finally, the FcC12SH probe is used to further study the reductive voltammetric desorption of alkylthiol SAMs. Defects in a C14S-Au SAM created by excursions to desorptive reduction potentials were quantified by use of the FcC12SH label. A reductive desorption potential followed by re-adsorption, applied to a binary (FcC12S-/C14S-Au) SAM, results in mixing of the phase separated components of the binary SAM.
