Microfluidic Focusing of Heterogeneous Bacterial Immunocomplexes for Reproducible SERS Immunoassays

Abstract Magnetic bead-based surface-enhanced Raman scattering (SERS) immunoassays enable sensitive and multiplexed bacterial detection. However, bacterial targets form heterogeneous magnetic bead–bacterium–SERS nanotag immunocomplexes that vary in size, morphology, and nanotag l...
