Abstract: According to an example, an apparatus for performing spectroscopy includes a perimeter wall extending between a first end and a second end of the perimeter wall along a first axis, in which an interior surface of the perimeter wall forms a hollow core extending along the first axis. The perimeter wall has openings at both the first end and the second end and light is to pass through the perimeter wall. The apparatus also includes a plurality of SES modules positioned around an inner circumference of the perimeter wall in a spaced arrangement with respect to each other to allow light to enter into the hollow core in gaps between the plurality of SES modules, in which each of the plurality of SES modules is positioned substantially across from a gap.

Abstract: In one example, an analyte detection package includes a substrate, surface-enhanced luminescence (SEL) structures extending from the substrate and a low wettability housing. The SEL structures have a first wettability for a given liquid. The low wettability housing extends from the substrate to form a chamber between the housing of the substrate about the SEL structures to receive an analyte containing solution. The housing has an inner surface adjacent the chamber, wherein the inner surface has a second wettability for the given liquid less than the first wettability.

Abstract: Provided in one example is an analyte detection apparatus that includes surface enhanced luminescence (SEL) structure. A dielectric layer underlies the SEL structure. An electric field generating base underlies the dielectric layer. The electric field generating base is to apply an electric field about the SEL structures to attract charged ions to the SEL structures.

Abstract: A system includes an illumination source, a detector and a processor. The detector acquires spectral measurements of a sample under test under at least one varying condition. The processor processes the measurements to generate at least one spectral representation that includes Raman spectra and at least one spectral representation that includes non-Raman spectra.

Abstract: Polarization selective surface enhanced Raman spectroscopy (SERS) includes a plurality of nanofingers arranged as a SERS multimer to exhibit a polarization-dependent plasmonic mode and one or both of a stimulus source and a Raman detector. The stimulus source is to illuminate the SERS multimer with a stimulus signal and the Raman detector is to detect a Raman scattering signal emitted by an analyte in a vicinity of the SERS multimer. One or both of the Raman scattering signal has a polarization state dictated by or associated with the polarization-dependent plasmonic mode and the stimulus signal has a polarization state corresponding to the polarization-dependent plasmonic mode.

Abstract: In an example, a device for sensing a property of a fluid may include an ion-sensitive field effect transistor (ISFET) having a gate, a source, and a drain. The device may also include a first metal element in contact with the gate and a switching layer in contact with the first metal layer. A resistance state of the switching layer is to be modified through application of an electrical field of at least a predefined strength through the switching layer and is to be retained in the switching layer following removal of the electrical field. The device may also include a metal plate in contact with the switching layer, in which the metal plate is to directly contact the fluid for which the property is to be sensed.

Abstract: According to an example, methods for forming three-dimensional (3-D) nano-particle assemblies may include depositing surface-enhanced spectroscopy (SES) elements onto respective tips of nano-fingers, in which the nano-fingers are arranged in sufficiently close proximities to each other to enable the tips of groups of adjacent ones of the nano-fingers to come into sufficiently close proximities to each other to enable the SES elements on the tips to be bonded together when the nano-fingers are partially collapsed. The methods also include causing the nano-fingers to partially collapse toward adjacent ones of the nano-fingers to cause a plurality of SES elements on respective groups of the nano-fingers to be in relatively close proximities to each other and form respective clusters of SES elements, introducing additional particles that are to attach onto the clusters of SES elements, and causing the clusters of SES elements to detach from the nano-fingers.
