Figure 4. Thermo-responsive SERS detection of single-analyte and dual-analyte.

Figure 4

(a,b) Schematic of the battery-controlled composite SERS system before and after voltage-on. (c,d) SERS spectra of 10−7 M R6G in response to voltage-off and voltage-on with an acquisition time of 30 s; (e,f) SERS spectra of PATP/R6G mixture (1.25 × 10−5 M: 1.25 × 10−6 M) in response to voltage-off and voltage-on. The lower SERS spectra in (e,f) are 5 × 10−5 M PATP and 5 × 10−6 M R6G respectively (acquisition time: 5 s). This figure was drawn by one of the coauthors (Qitao Zhou).
