Summary:A photonic sensing platform that utilizes the evanescent field of a subwavelength nanowire waveguide to perform optical spectroscopy on femtoliter probe volumes is demonstrated. Each evanescent sensor is capable of carrying out absorbance, fluorescence, and surface‐enhanced Raman spectroscopy measurements on the same analyte while operating within a microfluidic flow cell (see figure).
