AB  - It is of great significance to develop a simple and effective method for 
      constructing large-scale high-quality surface-enhanced Raman scattering (SERS) 
      substrate. Here, an Ag nanoparticle-assembled micro-bowl array was prepared by a 
      close-packed polystyrene (PS) sphere monolayer templated electrodeposition 
      approach. The fabricated Ag nanoparticle-assembled micro-bowl array shows high 
      SERS sensitivity to rhodamine 6G (R6G) under an ultra-low concentration of 1 fM, 
      and exhibits excellent SERS spectral uniformity with a small relative standard 
      deviation (RSD) of 7.6% and good reproducibility (a RSD  approximately 8.2% for the average 
      peak intensities from different batches of SERS substrates). The fabricated 
      micro-bowl array SERS substrate was employed to detect pesticide residue (thiram 
      and methyl parathion) on vegetables. The limit of detections (LODs) for the two 
      pesticides are lower than the maximum residue limits (MRLs) set by the European 
      Union respectively, showing promising application in rapid inspection of food 
      safety.
