Rhodamine B Derivatives-modified Upconversion Nanoparticles As a Fluorescent Turn-off-on Sensor for the Highly Sensitive Detection of Cu and Pyrophosphate
Overview
Affiliations
Rhodamine B derivatives (RBP)-modified UCNPs (UCNPs@mSiO-RBP) were developed as a fluorescent turn-off-on sensor based on FRET and IFE to detect Cu and pyrophosphate (PPi) with a wide linear response range (0-10 μM for Cu and 5-35 μM for PPi, much wider than that reported previously) and high sensibility (117 nM for Cu and 70 nM for PPi). The MTT experiments and the bioimaging experiments show its promising prospect in tissue imaging.
