    摘要： A NERS-active structure includes a deformable, active nanoparticle support structure for supporting a first nanoparticle and a second nanoparticle that is disposed proximate the first nanoparticle. The nanoparticles each comprise a NERS-active material. The deformable, active nanoparticle support structure is configured to vary the distance between the first nanoparticle and the second nanoparticle while performing NERS. Various active nanoparticle support structures are disclosed. A NERS system includes such a NERS-active structure, a radiation source for generating radiation scatterable by an analyte located proximate the NERS-active structure, and a radiation detector for detecting Raman scattered radiation scattered by the analyte. A method for performing NERS includes providing such a NERS-active structure, providing an analyte at a location proximate the NERS-active structure, irradiating the NERS-active structure and the analyte with radiation, varying the distance between the nanoparticles, and detecting Raman scattered radiation scattered by the analyte.

    摘要： An apparatus for sensing at least one property of a fluid is described. A first photonic crystal structure and a second photonic crystal structure are defined in a dielectric slab. The first and second photonic crystal structures comprise differently patterned arrays of channels extending through the dielectric slab. The apparatus further comprises a fluid introduction device configured to introduce a common volume of the fluid into the channels of the first and second photonic crystal structures. The at least one property of the fluid can be sensed by measuring the propagation of radiation through the first and second photonic crystal structures.

    摘要： A switching device includes at least one bottom electrode and at least one top electrode. The top electrode crosses the bottom electrode at a non-zero angle, thereby forming a junction. A metal oxide layer is established on at least one of the bottom electrode or the top electrode. A molecular layer including a monolayer of organic molecules and a source of water molecules is established in the junction. Upon introduction of a forward bias, the molecular layer facilitates a redox reaction between the electrodes, thereby reducing a tunneling gap between the electrodes.
