Figure 5

Separation and concentration of bacteria, SERS spectra, and detection result. (a) Separation and concentration of bacteria from a BC-bacteria mixture. Inset A1 shows a higher magnification photo of the center area; there is a high density of bacteria aggregate without blood cells at the center. (b) The SERS spectra of RBC, RBC-bacteria mixture, and the S. aureus dielectrokinetically separated from blood. (c) The detection result shows very distinct fingerprints of S. aureus and P. aeruginosa that were measured after separation and AgNP-bacteria sorption.
