(a) Fluorescence spectra of F-hPEI-capped Au NPs with the addition of different concentrations of Cr (VI) ranging from 0 μM to 2.9×102μM. (b) The corresponding calibration curve for this sensor over the range from 2.8 μM to 29 μM. The error bars represent the standard deviation of three measurements.
