(A) Illustration of the vancomycin and aptamer dual-recognition FRET assay for detection of S. aureus) (B) Fluorescence spectra of the FRET biosensor in the presence of S. aureus at varying concentrations (curves a-l correspond to 0, 10, 20, 30, 10², 10³, 10⁴, 10⁵, 10⁶, 10⁷, 5 × 10⁷ and 10⁸ CFU/mL, respectively). (C) Calibration curve showing the linear relationship between fluorescence intensity and the logarithm of S. aureus concentration (log₁₀N CFU/mL).
