SERS spectra without sample pretreatment. SERS spectra of (a) goat blood spiked with S. aureus (1 × 109 CFU/ml) without ACK treatment and sonication, (b) hemoglobin, (c) reference strain of S. aureus, and (d) goat blood spiked with S. aureus with ACK treatment and sonication. Black curves represent the mean SERS spectra, while gray curves represent their corresponding standard deviation.
