Abstract: A vibrating tip surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a nano-needle configured to vibrate. The apparatus includes the nano-needle with a substantially sharp tip at a free end opposite an end attached to a substrate. The tip is configured to adsorb an analyte. The apparatus further includes a vibration source configured to provide an alternating current (AC) electric field that induces a vibration of the free end and the tip of the nano-needle. Vibration of the nano-needle under the influence of the AC electric field facilitates detection of a Raman scattering signal from the analyte adsorbed on the nano-needle tip. The system further includes a synchronous detector configured to be gated cooperatively with the vibration of the nano-needle. The method includes inducing the vibration, illuminating the vibrating tip to produce a Raman signal, and detecting the Raman signal using the detector.

Abstract: An optical sensor, sensing system and method of sensing employ a half-core hollow optical waveguide adjacent to a surface of an optical waveguide layer of a substrate. The half-core hollow optical waveguide and the adjacent optical waveguide layer cooperatively provide both an optical path that confines and guides an optical signal and an internal hollow channel. The optical path and channel extend longitudinally along a hollow core of the half-core hollow optical waveguide. The system further includes an optical source at an input of the optical path and an optical detector at an output of the optical path. A spectroscopic interaction between an analyte material that is introduced into the channel and an optical signal propagating along the optical path determines a characteristic of the analyte material.
