Ag decorated sandpaper as flexible SERS substrate for direct swabbing sampling

Sandpaper was used as template for vacuum deposition of silver as SERS substrate. Swabbing tests of pesticide on different surfaces were demonstrated. To the best of our knowledge, this is the first SERS substrate that can swab detect pesticide on real-life surfaces. Sandpaper was used as template f...

Summary:Sandpaper was used as template for vacuum deposition of silver as SERS substrate. Swabbing tests of pesticide on different surfaces were demonstrated. To the best of our knowledge, this is the first SERS substrate that can swab detect pesticide on real-life surfaces. Sandpaper was used as template for vacuum deposition of silver as SERS substrate. Swabbing tests of pesticide on different surfaces were demonstrated. [Display omitted] •Sandpaper was used as template for vacuum deposition of Ag as SERS substrate (swab).•The SERS swab is highly sensitive and reproducible.•Compared with commercial SERS substrate, the swab is flexible and at very low cost.•The fabrication process can easily scale up for potential commercial applications.•Direct SERS swabbing sampling of pesticide on real life surfaces was realized.
