Characterization of the SERS micropipettes in different sections. a Photograph of optical microscopy and SEM. Three sections (A, B, C) of the micropipette with different curvatures are chosen for the observation of the film morphologies. The corresponding curvatures of sections A, B, and C are listed in the table. b Raman spectra of SERS micropipette with the detection location moved from the tip to the column end
