The material available here was first presented as a poster at the 2017 North American Chemical Residue Workshop. The material describes how we utilized a swabbing technique to detect trace levels of pesticides on apple skin, including malathion, phosmet, imidacloprid, and thiram, using our gold nanoparticle based SERS substrates and a Raman experimental setup that involves 785 nm laser excitation and a thermoelectrically cooled Ocean Optics CCD spectrometer.
