Abstract: This disclosure relates to sensors comprising an elastomeric body incorporating a plurality of discrete electrical conductors such that an electrically conductive path can be formed within the elastomeric body via conduction between neighbouring conductors, and the elastomeric body includes at least one slit passing between neighbouring conductors. These sensors may be included in circuit structures, decals and vibration sensors. Also disclosed are methods of preparing the sensors, circuit structures and decals, and methods of using the sensors, circuit structures and decals.

Abstract: An elastic conductor comprising: an elastomeric substrate, and an array of nanowires, wherein the nanowires are upstanding relative to the surface of the substrate.

Abstract: Ultrathin plasmene nanosheets are demonstrated as a new class of flexible surface enhanced Raman scattering (SERS) substrate capable of conformal attachment and sensitive and reproducible detection of chemicals on topologically complex surfaces. Engineering building block morphologies allows for fine-tuning of the SERS performance. In a preferred application the plasmene nanosheets are demonstrated as the next generation plasmonic and/or SERS coded labels, such as for example, anti-counterfeit security label for banknotes. Engineering the morphologies of plasmene-constituent nanoparticles and varying of SERS molecular labels offer virtually unlimited coding capacities.

Abstract: Apparatus and methods for forming self-assembly arrays of substances, such as nanoparticles, on a substrate are disclosed. The apparatus may include a substrate supporting a liquid composition including the substance and a solvent, and a removable micro-mold placed over the substrate and the liquid composition. To form the self assembly arrays of the substance, the solvent may be evaporated through at least one evaporation channel formed between the micro-mold and the substrate. The evaporation channel may be adjustable by subjecting the micro-mold to a positive pressure.

Abstract: A self-assembly nanodevice formed through nucleic acid engineering is disclosed. The nanodevice may include an array of nanoparticles. The nanodevice may further include a substrate that supports the array of nanoparticles. Each of the nanoparticles may be coordinated with a plurality of nucleic acids that are substantially free of Watson-Crick base-paring with nucleic acids coordinated with other nanoparticles. Methods of forming the nanodevice, as well as the microscopic organization of the nanoparticles are also disclosed. By manipulating the nucleic acids as capping ligands, the inter-particle distance may be extended to a greater range than nanotechnology based on alkyl ligands or nucleic acids base-pairing.
