PROBLEM TO BE SOLVED: To provide a system for performing surface-enhanced spectroscopy (SES), and a method for manufacturing an apparatus for performing the SES.SOLUTION: An apparatus for performing surface-enhanced spectroscopy (SES) includes an elongated substrate 102 having a shape and size to be inserted into a specimen, where the elongated substrate has a first end part 104 and a second end part 106. The apparatus also includes a plurality of surface-enhanced spectroscopy (SES) elements 110 positioned on an exterior surface of the elongated substrate at a location between the first end part 104 and the second end part 106 of the elongated substrate 102.SELECTED DRAWING: Figure 1A
