Label-free detection of live bacteria using growth medium enhanced with Au nanoparticles
CFU/mL at 95% confidence. Since each parameter extracted from the experimental spectra was subject to some scatter, a three-channel calibration based on the equally weighted average of the individual calibration curves based on attenuance, wavelength of the aggregation plasmon peak and spectral correlation was also investigated. This provided an even lower detection limit of 360 CFU/mL at 95% confidence.
