摘要：

A novel, recyclable, portable, and low-cost SERS sensor-AuBPs@MoS2@tinfoil box is fabricated layer-by-layer by self-assembly method for the first time, which achieved the purpose of high throughput SERS tracking. Diquat (DQ) is one of the most widely used herbicides in the world since paraquat was banned. Benefiting from the "hot spots" generated by AuBPs@MoS2, the sensor successfully realizes straightforward SERS recognition of DQ in complex compounds, which detection limit is as low as 1.0 x 10-15 M. The preprocessing is not required for the detection of real samples, which promotes the practical application of forensic medicine and environmental engineering.
