    摘要: The invention provides new types of plasmon-driven growth mechanism for silver nanostructures involving the fusion of triangular nanoprisms. This mechanism, which is plasmon excitation-driven and highly cooperative, produces bimodal particle size distributions. In these methods, the growth process can be selectively switched between bimodal and unimodal distributions using dual beam illumination of the nanoparticles. This type of cooperative photo-control over nanostructure growth enables synthesis of monodisperse nanoprisms with a preselected edge length in the 30-120 nm range simply by using one beam to turn off bimodal growth and the other (varied over the 450-700 nm range) for controlling particle size.

    摘要: A novel coordination chemistry or metal ion binding approach to controlling the site-isolation and orientation of virus particles, such as TMV, on a nanoarray template generated by lithography including Dip Pen Nanolithography. By using the surface chemistry that is inherent in many viruses, metal-ion based or inorganic coordination chemistry was used to immobilize individual virus particles without the need for their genetic modification. Single particle control will enable a wide variety of studies involving viruses that are not possible with microarrays because of the size mismatch between the architecture of the virus and the features that make up such arrays. These include: single particle, single cell infectivity studies, the exploration of such structures as templates in materials synthesis and molecular electronics, and studies aimed at understanding how surface presentation can influence their bioactivity. This is a pioneering example of such control at the single-particle level, and therefore, commercial use of nanoarrays in biological systems.

    摘要: The invention provides a lithographic method referred to as “dip pen” nanolithography (DPN). DPN utilizes a scanning probe microscope (SPM) tip (e.g., an atomic force microscope (AFM) tip) as a “pen,” a solid-state substrate (e.g., gold) as “paper,” and molecules with a chemical affinity for the solid-state substrate as “ink.” Capillary transport of molecules from the SPM tip to the solid substrate is used in DPN to directly write patterns consisting of a relatively small collection of molecules in submicrometer dimensions, making DPN useful in the fabrication of a variety of microscale and nanoscale devices. The invention also provides substrates patterned by DPN, including submicrometer combinatorial arrays, and kits, devices and software for performing DPN. The invention further provides a method of performing AFM imaging in air. The method comprises coating an AFM tip with a hydrophobic compound, the hydrophobic compound being selected so that AFM imaging performed using the coated AFM tip is improved compared to AFM imaging performed using an uncoated AFM tip. Finally, the invention provides AFM tips coated with the hydrophobic compounds.

    摘要: Polymeric microstructures and nanostructures can be prepared with use of a tip to pattern a surface. A tip can be used to pattern a structure which can initiate polymerization. The structure can be then exposed to monomer to induce polymerization at the structure. Alternatively, a tip can be used to pattern a surface with a monomer in which the surface is treated with polymerization catalyst so that polymerization occurs at the patterning site. Ring-opening metathesis polymerization can be carried out with use of the tip to control the polymerization. The tip can be a sharp tip as used in for example an atomic force microscope tip. Norbornene types of monomers can be used. Biological macromolecules can be also prepared.
