Fig. 2From: Molecularly Imprinted Core-Shell CdSe@SiO2/CDs as a Ratiometric Fluorescent Probe for 4-Nitrophenol SensingFluorescence of the prepared hybrid nanoparticles. a Fluorescence emission spectra of the CdSe@SiO2/CD/MIP nanoparticles before (black line) and after (red line) removal of the template molecules and b their photo-stability dispersed in ethanol following the removal of 4-NP. c Adsorption capacities of the CdSe@SiO2/CD/MIP and CdSe@SiO2/CD/NIP nanohybrids. d The plots of the fluorescence intensity of CdSe@SiO2/CDs/MIP and CdSe@SiO2/CDs/NIP with 4-NP, respectively. (Fb0 and Fb represent the fluorescence intensity of CdSe@SiO2/CDs/MIP and CdSe@SiO2/CDs/NIP at 455 nm in the absence and presence of various amounts of 4-NP)Back to article page
