The detection of 4-NP. a Fluorescence spectra of the CdSe@SiO2/CD/MIP nanohybrids obtained at increasing 4-NP concentrations under an excitation wavelength of 350 nm. b Effect of 4-NP concentration on the ratio of F r to F b for the MIP-coated CdSe@SiO2/CD nanohybrids. 4-NP concentrations of 0.051, 2.1, 4.8, 6.7, 8.9, 11.52, and 13.7 μg/mL were employed. F b and F r represent the fluorescence intensities of the CdSe@SiO2/CD/MIP nanohybrids at 455 and 615 nm, respectively
