Abstract:
1. A waveguide for use with surface-enhanced Raman spectroscopy, comprising: a base structure having an inner surface that defines a through cavity through the base structure, wherein the inner surface extends about an axis such that the through cavity extends in an axial direction, wherein an analyte is capable of being transferred via the through cavity, wherein the base structure has an axial length that is longer than a radial length of the base structure; a base layer located on the inner surface of the base structure, wherein the base layer extends in the axial direction along an axial length of an excitation section; nanoparticles bonded to the base layer; a first micro-lens that directs an excitation light generated by a laser into the through cavity; a second micro-lens, for receiving the excitation light and transmitting the light to a data collection sensor; wherein when the excitation light is directed into the through cavity of the base structure by the first micro-lens a plurality of molecules of the analyte are present within the through cavity and the second micro-lens receives the light from the through cavity and directs it to the sensor and wherein the laser and the first micro lens are located on one side of the base structure and the second micro-lens and the sensor are located on an opposite side of the base structure.
