Copper ions (Cu2+) play a key role in ecosystems and human health, however, the copper pollution caused by the excessive use of copper has become one of the main problems of modern world. In this paper, a facile method was developed to construct a multifunctional nanoprobe for Cu2+ detection by combining the mesoporous silica coated upconversion nanoparticles (UCNPs) with rhodamine B derivative. β-NaYF...
Cysteine, as a small organic molecule and amino acid, is a basic building block for proteins and has special physiological functions in vivo. Cysteine has strong affinity for cells, which can be taken advantage for various applications. A new and facile surface modification method has been developed for rare-earth doped upconversion nanoparticles (UCNs) using cysteine. Compared with unmodified samples,...
