Detection of miRNA-155 with fluorescent probes of MB-UCNP@SiO2 + QDs. A Plots of fluorescence spectra for the detection of different miRNA-155 concentrations. B Plot of the relationship between the fluorescence intensity ratio and the logarithm of miRNA-155 concentration. C Plots of fluorescence spectra for the detection of miRNAs with different base sequences. D Histogram of fluorescence peak intensities for the corresponding spectra shown in C. The error bars represent the standard deviation from the three measurements
