Techniques regarding nanofluidic chips with a plurality of inlets and/or outlets in fluid communication with one or more nanoDLD arrays are provided. For example, one or more embodiments described herein can comprise a nanoscale deterministic lateral displacement array between and in fluid communication with a global inlet and a global outlet. The nanoscale deterministic lateral displacement array can further be between and in fluid communication with a local inlet and a local outlet. Also, the nanoscale deterministic lateral displacement array can laterally displace a particle comprised within a sample fluid supplied from the global inlet to a collection region that directs the particle to the local outlet. An advantage of such an apparatus can be the expanded versatility of the nanoscale deterministic lateral displacement array for sample preparation applications involving nanoparticles not accessible to other higher throughput microscale microfluidic technologies.

The present disclosure provides an article including an organic layer having a nanostructured first surface including nanofeatures defining nanorecesses and an opposing second surface; and a ceramic layer disposed on the nanostructured first surface of the organic layer and filling at least a portion of the nanorecesses. The ceramic layer has a nanostructured first surface including nanofeatures and an opposing second surface, and the nanostructured first surface of the ceramic layer is interpenetrated with the nanostructured first surface of the organic layer. The present disclosure also provides a method of making the article. The method includes obtaining an organic layer having a nanostructured first surface including nanofeatures defining nanorecesses and an opposing second surface; and filling at least a portion of the nanorecesses of the nanostructured first surface of the organic layer with a ceramic material to form the article. In addition, the present disclosure provides articles including interpenetrating layers having different elastic storage moduli, such as non-metallic layers, and methods of making the articles. The articles can exhibit high abrasion resistance.

A new class of ordered functional nanoporous material (OFNMs) with a unique combination of electronic conductivity, gas transport ability, and ion transport properties are provided. The OFNM provided is highly ordered and contains nanometer scale pores lined with nitrogen atoms. The pores have dimensions of from 1.2 nm to 82 nm of longest linear extent across the pore. The functionality within the pore is controlled through selection of groups that extend into the pore. The degree of conjugated aromaticity is readily controlled to adjust the electrical conductivity properties of the resulting structure. By adjusting the groups external to the pore, three-dimensional structures are formed that are organic mimics of zeolites, metal organic frameworks (MOF), or perovskites.

Nanoassembly methods for producing quasi-3D plasmonic films with periodic nanoarrays of nano-sized surface features. A sacrificial layer is deposited on a surface of a donor substrate having periodic nanoarrays of nanopattern features formed thereon. A plasmon film is deposited onto the sacrificial layer and a dielectric spacer is deposited on the plasmon film. The donor substrate having the sacrificial layer, plasmon film, and dielectric spacer thereon is immersed in a bath of etchant to selectively remove the sacrificial layer such that the plasmon film and the dielectric spacer thereon adhere to the surface of the donor substrate. The dielectric spacer and the plasmon film are mechanically separated from the donor substrate to define a quasi-three dimensional (3D) plasmonic film having periodic nanoarrays of nano-sized surface features defined by the nanopattern features of the donor substrate surface. The quasi-3D plasmonic film is then applied to a receiver substrate.

A 3D nanopore device for characterizing biopolymer molecules includes a first selecting layer having a first axis of selection. The device also includes a second selecting layer disposed adjacent the first selecting layer and having a second axis of selection orthogonal to the first axis of selection. The device further includes an third electrode layer disposed adjacent the second selecting layer, such that the first selecting layer, the second selecting layer, and the third electrode layer form a stack of layers along a Z axis and define a plurality of nanopore pillars.

Embodiments relate to an apparatus for forming nano-structures with tailored properties on objects while fabricating the objects. The apparatus includes a reservoir that holds compositions therein. Each of the compositions includes a nano-structural material, a plurality of grain growth inhibitor nano-particles, and at least one of a tailoring solute and a plurality of tailoring nano-particles. A nozzle is operatively coupled to the reservoir and a translatable stage is positioned proximate to the nozzle. The stage includes a substrate holder adapted to hold a substrate. A surface profile determination device is positioned proximate to the stage to obtain profile data of the substrate. A control unit is operatively coupled to the device and the stage and regulates manufacture of a pinned nano-structure. The control unit forms deposition layers positioned proximal to the substrate with the compositions through electrospray techniques.

Variations provide a metamaterial comprising a plurality of metamaterial repeat units containing a surface-patterned nanoparticle or microparticle that is coated with a metal in a surface pattern. The surface-patterned particle may include a dielectric material or a semiconductor material partially or fully coated with metal(s). In some embodiments, the surface-patterned particles are split ring resonators. Some variations provide a method of making a metamaterial, the method comprising: metallizing surfaces of particles, wherein particles are coated with metal(s) in a surface pattern; dispersing surface-patterned particles in a liquid solution at a starting pH; introducing a triggerable pH-control substance capable of generating an acid or base; and triggering the pH-control substance to generate an acid or base, thereby adjusting the solution pH to a titrated pH. The zeta potential is closer to zero at the titrated pH compared to the starting pH, causing the surface-patterned particles to assemble into a metamaterial.
