Bioaerosol characterization by surface-enhanced Raman spectroscopy (SERS) [PDF]
Journal of Aerosol Science, 2005 It is demonstrated that bioaerosols can be characterized by their surface-enhanced Raman spectra. Preliminary studies showed that Raman spectra of aqueous suspensions of Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhimurium can be obtained by mixing them with a nanocolloidal suspension of silver.
