To enable us surface enhanced Raman scattering (SERS) spectroscopic detection of bacteria having low affinity for Ag colloidal nanoparticles, we examined simple experimental methodology; SERS detections using Ag nanoparticles aggregates directly synthesized by photo-reduction on the surfaces of such bacteria (Helicobacter pylori). The synthesized Ag nanoparticles aggregated on bacterial surfaces and...
