A myriad of core/shell nanoparticles (NPs) have been developed and studied in the last decades aiming at the increase of functionality, stability, dispersibility, biocompatibility, and specific targeting, for instance.1 Shells can also interact synergetically with the core by changing lattice parameters, resulting in strain-engineered materials with tuned, improved, and new properties.2,3 This ...
Preparation and characterization of carbonyl iron/poly(butylcyanoacrylate) core/shell nanoparticles.
In this article a method is described to prepare composite colloidal nanoparticles, consisting of a magnetic core (carbonyl iron) and a biodegradable polymeric shell [poly(butylcyanoacrylate) or PBCA]. The method is based on the so-called anionic polymerization procedure, often used in the synthesis of poly(alkylcyanoacrylate) nanospheres designed for drug delivery. Interest of this investigati...
Polyelectrolyte-coated nanoparticles consisting of terbium and gadolinium complexes with calix[4]arene tetra-diketone ligand were first synthesized. The antenna effect of the ligand on Tb(III) green luminescence and the presence of water molecules in the coordination sphere of Gd(III) bring strong luminescent and magnetic performance to the core-shell nanoparticles. The size and the core-shell ...
Novel amino- or thiol-functionalized superparamagnetic copolymer-silica nanospheres (NH2-SMCSNs/SH-SMCSNs), which consist of a magnetic core and a silica cross-linked block copolymer shell, have been fabricated.
