Abstract: A surface enhanced Raman spectroscopy (SERS) apparatus employs a nanorod in an indentation in a surface of a substrate. The SERS apparatus includes the nanorod having a tip at a free end opposite to an end of the nanorod that is supported by the substrate indentation. The indentation has a tapered profile and supports the nanorod at a bottom of the indentation. The free end of the nanorod extends away from the indentation bottom. The SERS apparatus further includes a Raman-active material at a surface of one or both of the nanorod and the indentation. The indentation and the nanorod facilitate one or both of production and detection of a Raman scattering signal emitted by an analyte in a vicinity of the nanorod and indentation.

Abstract: A scattering spectroscopy nanosensor includes a nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte when interrogated by an optical stimulus. The scattering spectroscopy nanosensor further includes a protective covering to cover and protect the nanoscale-patterned sensing substrate. The protective covering is to be selectably removed by exposure to an optical beam incident on the protective covering. The protective covering is to prevent the analyte from interacting with the nanoscale-patterned sensing substrate prior to being removed.
