Highly luminescent biocompatible CsPbBr3@SiO2 core–shell nanoprobes for bioimaging and drug delivery

A facile approach for the highly luminescent and biocompatible CsPbBr₃@SiO₂ core–shell PNCs was developed. The dual biological roles of these PNCs are demonstrated, offering new directions to the stable PNCs for a variety of biomedical applications.
