    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.

    Abstract: The present disclosure is drawn to chemical sensing devices and associated methods. In one example, a chemical sensing device can include a substrate; an elongated nanostructure having an attachment end and a free end opposite the attachment end, the attachment end affixed to the substrate and the free end including a metal; and a metal oxide coating applied to the elongated nanostructure. In one example, a functional group can be attached to the coating via a covalent bond.

    Abstract: According to an example, an apparatus for performing spectroscopy includes a substrate on which a plurality of surface-enhanced spectroscopy (SES) elements are positioned substantially along a first plane. The apparatus also includes a first electrode positioned adjacent to the plurality of SES elements substantially along the first plane and a second electrode positioned adjacent to the plurality of SES elements substantially along the first plane and on a side of the plurality of SES elements that is opposite the first electrode. The first electrode and the second electrode are to generate an electric field around the plurality of SES elements when voltages are applied through the first electrode and the second electrode.

    Abstract: An electrically driven device for surface enhanced Raman spectroscopy includes a substrate, a Raman signal-amplifying structure positioned on the substrate, and an analyte receptor attached to a structure chosen from i) the Raman signal-amplifying structure, or ii) the substrate near the Raman signal-amplifying structure, or iii) combinations of i and ii. The analyte receptor has a selective binding affinity for an analyte. Conductive elements are positioned relative to one another and to the analyte receptor such that the conductive elements together produce an electric field in the vicinity of the analyte receptor when a voltage bias is applied between the conductive elements.
