One-pot self-assembly of multifunctional mesoporous nanoprobes with magnetic nanoparticles and hydrophobic upconversion nanocrystals

A simple and versatile method was proposed for self-assembling magnetic nanoparticles and hydrophobic upconversion nanoparticles on to a mesoporous nanoprobe by the means of an electrostatic interaction and binding scheme. The hybrid nanoprobes showed good magnetic and near-infrared luminescent properties, and could be explored as biosensors.
