One embodiment is a nanostructured arrangement having a base and pyramidal features formed on the base. Each pyramidal feature includes sloping sides converging at a vertex. The nanostructured arrangement further includes a nanostructured surface formed on at least one of the sloping sides of at least one of the pyramidal features. The nanostructured surface has a quasi-periodic, anisotropic array of elongated ridge elements having a wave-ordered structure pattern. Each ridge element has a wavelike cross-section and oriented substantially in a first direction.

A technique related to sorting entities is provided. An inlet is configured to receive a fluid, and an outlet is configured to exit the fluid. A nanopillar array, connected to the inlet and the outlet, is configured to allow the fluid to flow from the inlet to the outlet. The nanopillar array includes nanopillars arranged to separate entities by size. The nanopillars are arranged to have a gap separating one nanopillar from another nanopillar. The gap is constructed to be in a nanoscale range.

Abstract:
Methods for fastening nanoscale structures within an anchoring structure to form a nanostructure composite and nanostructure composites formed therefrom. A primary fluid layer is formed on an anchoring substrate. Nanostructures are provided on an initial substrate, the nanostructures having a defined height and orientation with respect to the initial substrate. The nanostructures are introduced to a desired depth in the primary fluid layer, such that the orientation of the nanostructures relative to the growth substrate is substantially maintained. The primary fluid layer comprises one or more fluid layers. Ones of multiple fluid layers are selected such that when altered to form an anchoring structure, a portion of the anchoring structure can be removed, permitting exposure of at least a portion of the nanostructures from the anchoring structure in which they are affixed. The growth substrate is removed. Ends or other parts of nanostructures may be exposed from the anchoring structure.
Abstract:
A method of making a nanotube array structure includes forming a nanorod array template on a substrate, coating a nanotube material over the nanorod array template, forming a coated template, annealing the coated template, and drying the coated template. The method then includes heating the coated template to an elevated temperature, relative to ambient temperature, at a heating rate while flowing a gas mixture including a reducing gas over the substrate at a flow rate, the reducing gas reacting with the nanorod array template and forming a gaseous byproduct and the nanotube array structure in which nanotubes may be substantially aligned with adjacent nanotubes. The nanotube array structure can be used, for example, in sensor, catalyst, transistor, or solar cell applications.

The bio-programmable crystallization of muIti-component functional nanoparticle systems is Ascribed, as well as methods for such bio-programmable crystallization, and the products resultant from such methods. Specifically, the systems disclosed and taught herein are directed to improved strategies for the DNA-mediated self-assembly of multi-component functionalized nanoparticles into three-dimensional order surperlattices, wherein the functionalization of the nanoparticles with DNA is independent of either the composition of the material, or the shape of the nanoparticles.
Abstract:
The present invention is directed to nanoscale fabrication of nano-materials with application in electronics, energy conversion, bio-sensing and others. Specifically, the invention is directed to arbitrary, that is periodic and non-periodic, assembly of nano-objects on I D and 2D arrays. The present invention utilizes self-organization properties of nanoscale bio-encoded building blocks, programmability of biomolecular interactions, and simple processing techniques for providing arbitrary by-design fabrication capability. Specifically, the present invention utilizes double stranded DNA attached to a surface and intercalating PNA-DNA hybrids attached to nano-objects to bind the nano-objects to the dsDNA in a site specific manner. The present invention allows for an integration of a large number of nano-components in unified well-defined systems. Accordingly, the present invention is applicable for fabrication of I D and 2D structures of various by-design placements of nano-objects of multiple types, including metal, semiconducting and organic nano-objects.
