Abstract: A method for forming a surface-enhanced fluorescence spectroscopy (SEFS) apparatus may include depositing a plurality of surface-enhanced spectroscopy (SES) elements onto respective tips of a plurality of nano-fingers, wherein the nano-fingers are arranged in sufficiently close proximities to each other to enable the tips of a group of adjacent nano-fingers to come into sufficiently close proximities to each other to enable the SES elements on the tips to trap fluorescent probe molecules that are to bind with target molecules when the nano-fingers are partially collapsed.

Abstract: An example memristor includes a first conductive layer, a switching layer, and a second conductive layer. The first conductive layer may include a first conductive material and a second conductive material. The second conductive material may have a higher diffusivity than the first conductive material. The switching layer may be coupled to the first conductive layer and may include a first oxide having the first conductive material and a second oxide having the second conductive material. The second conductive layer may be coupled to the switching layer.

Abstract: The present disclosure is drawn to a device for monitoring and controlling live cells and associated methods. In an example, the device can include a plurality of elongated nanostructures affixed to a substrate. The elongated nanostructures can each have an attachment end and a free end opposite the attachment end. The free end includes a metal and the attachment end is affixed to the substrate. The device can further include a functionalization layer that is coated on the free end of at least a portion of the plurality of elongated nanostructures. The functionalization layer can be formulated to retain live cells, and the device can be configured to be used in conjunction with a detector, such as a Raman spectrometer, in order to monitor growth of live cells.

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.
