  • Title: Detection of low concentrations of ampicillin in milk.
    Author: Andreou C, Mirsafavi R, Moskovits M, Meinhart CD.
    Journal: Analyst; 2015 Aug 07; 140(15):5003-5. PubMed ID: 26087055.
    Abstract:
    Ampicillin, a common antibiotic, is detected at trace concentrations in milk using surface enhanced Raman spectroscopy in a microfluidic device, using less than 20 μL of sample, in 10 minutes, with minimal off-chip preparation. The device is configured so as to favor the interaction of the analyte with colloidal silver, and the optimization of the aggregation of the silver nanoparticles so as to increase the SERS intensity and the consequential sensitivity of analyte detection.
