Application Note: Trace Level Detection of Pesticides on Apple Skin
SERS is a potentially useful tool for identifying pesticide residues on the surface of fruits for food quality and safety control.
Pesticides play a critical role in protecting food crops from insects, fungi, weeds, and other unwanted pests. The increasing use of these pesticides to maintain food production and quality leads to potentially dangerous residues remaining on the food products. A rapid and non-destructive technique for trace level detection of pesticides at parts-per-million (ppm) or parts-per-billion (ppb) is surface-enhanced Raman spectroscopy (SERS).
