    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: 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: A chemical-analysis device integrated with a metallic-nanofinger device for chemical sensing. The chemical-analysis device includes a metallic-nanofinger device, and a platform. The metallic-nanofinger device includes a substrate, and a plurality of nanofingers coupled with the substrate. A nanofinger of the plurality includes a flexible column, and a metallic cap coupled to an apex of the flexible column. At least the nanofinger and a second nanofinger of the plurality of nanofingers are to self-arrange into a close-packed configuration with at least one analyte molecule. A morphology of the metallic cap is to generate a shifted plasmonic-resonance peak associated with amplified luminescence from the analyte molecule. A method for using, and a chemical-analysis apparatus including the chemical-analysis device are also provided.

    Abstract: According to an example, methods for forming three-dimensional (3-D) nano-particle assemblies include depositing 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.
