AB  - The analysis of contaminants in migration of food contact material (FCMs) is an 
      urgent demand for food safety. In this study, melamine and formaldehyde in 
      melamine kitchenware were selectively analyzed by surface-enhanced Raman 
      scattering (SERS) via aptamer/derivatization-based membrane assembly. The 
      membrane assembly was designed by simple filtration of Ag nanoparticles-decorated 
      "stellate" silicon dioxide (SiO(2)/Ag) and composites of reduced graphene oxide 
      and Ag nanoparticles (rGO/Ag) functioned with specific reagents. High selectivity 
      can be realized by melamine aptamer and derivatization reagent of formaldehyde, 
      respectively. The relative standard deviations (RSDs) of melamine and 
      formaldehyde analysis for 11 replicate measurements, 14 consecutive days and 25 
      batches are less than 6.0 %, which shows excellent repeatability and 
      reproducibility. After the method was validated, the limits of detection (LOD) 
      for melamine and formaldehyde are 0.15 mg/L and 0.21 mg/L, respectively. The 
      developed method was applied to determine the content of melamine and 
      formaldehyde in migration of melamine kitchenware with low relative errors (less 
      than 5.3 %) compared to chromatographic results. The recoveries of melamine and 
      formaldehyde for migrations of melamine kitchenware are 91.2-110.0 % and 
      94.0-106.0 % with RSDs in range of 1.8-8.3 % and 4.7-9.1 %, respectively. The 
      method proposed a new concept of convenient, portable and reliable strategy for 
      analysis of melamine and formaldehyde in migration from FCMs.
