Figure 5

(a) Schematic details the collection and SERS-based detection of BTs on the left and 4-FBT on the right. (b) Associated confocal Raman microscope intensity maps at wavenumbers 1,001 cm−1 and 1,075 cm−1 next to the (c) corresponding SERS spectra. (d) The fluorescent microscopy image shows the green fluorescence of large macromolecular anti-mouse IgG proteins, which are funneled into the photoresist hole pattern. (b) Scale bar, 1 μm; (d) 3 μm.
