Rapid SERS Detection of Thiol-Containing Natural Products in Culturing Complex
Figure 6
(a–i) SERS spectra of target thiols in the bacterial medium (black) in comparison with the SERS spectra of pure thiol (blue) and the cultured bacterial medium (CM, red). The concentrations of the target thiols in CM are 5.0 × 10−6 M for (a, b, d, e, f, and i) and 5.0 × 10−5 M for (c, g, and h). The dotted lines mark the corresponding SERS features.
