Target‐Cell‐Specific Delivery, Imaging, and Detection of Intracellular MicroRNA with a Multifunctional SnO₂ Nanoprobe

Abstract

Right on target: A multifunctional nanoprobe is designed for target-cell-specific imaging and in situ detection of intracellular miRNA. The nanoprobe is prepared by functionalizing SnO2 nanoparticles with both folic acid (FA), a target-cell-specific moiety to recognize folate receptors overexpressed on cancer cells, and a gene probe to inhibit or recognize intracellular miRNA levels (see scheme).
