Hydrophobic paper-based SERS platform for direct-droplet quantitative determination of melamine

•A paper-based SERS substrate with good activity and reproducibility was proposed.•The SERS platform can be reused to construct the super-hydrophobic surface.•Direct droplet-detection realizes quantitative SERS determination.•The detection limit of melamine in milk is down to 1 ppm. A novel hydropho...
