Additionally, the reported effects of pesticides on human health range from short-term, such as skin irritation and headaches, to chronic effects, such as asthma and cancer. Surface enhanced Raman scattering (SERS) is an enhancement technique used with Raman spectroscopy to provide lower limits of detection. SERS offers a signal enhancement of up to 1010-1015 and also advantageously quenches the fluorescence of analytes
