Ampicillin 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 tailors the aggregation reaction of silver nanoparticles so as to increase the SERS intensity and sensitivity.
