Nanoreactors: A Hybrid Silica Nanoreactor Framework for Encapsulation of Hollow Manganese Oxide Nanoparticles of Superior T1 Magnetic Resonance Relaxivity (Adv. Funct. Mater. 33/2015)

A hybrid silica nanoreactor framework with poly(ethylene oxide) (PEO)-perforated silica walls is designed to prepare hollow MnO nanoparticles with different nanocomposite architectures under highly controlled conditions, by X. Li, J. Wang, and co-workers on page 5269. The resultant hollow nanoparticles are integrated within the hybrid nanoreactor, and are shown to demonstrate good contrast in magnetic resonance imaging for an optimal cluster on nanoparticles in the framework.
