    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: A method for fabricating scanning probe microscopy (SPM) probes is disclosed. The probes are fabricated by forming a structural layer on a substrate, wherein the substrate forms a cavity. A sacrificial layer is located between the substrate and the structural layer. Upon forming the structural layer, the sacrificial layer is selectively removed, and the probe is then released from the substrate. The substrate may then later be reused to form additional probes. Additionally, a contact printing method using a scanning probe microscopy probe is also disclosed.
