Rapid detection of thiram using a dynamic ratiometric in-tube SPME-SERS strategy.
Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for pesticide detection but is hindered in field applications by slow analyte mass transport and quantitative irreproducibility. Herein, we report an in-tube solid-phase microextraction-SERS (in-tube SPME-SERS) strategy that simultaneously overcomes these bo...
