Continuous chemical operations and modifications on magnetic gamma-Fe2O3 nanoparticles confined in nanoliter droplets for the assembly of fluorescent and magnetic SiO2@gamma-Fe2O3, Chem. Comm. 2015, DOI : 10.1039/C5CC07044A
Abstract
We present a microfluidic platform that allows undergoing different chemical operations in a nanoliter droplet starting from the colloidal suspension of magnetic iron oxide (c-Fe2O3) nanoparticles ‘‘NPs’’ (ferrofluid). These operations include : mixing, flocculation, magnetic decantation, colloidal redispersion, washing, surface functionalization, heating and colloidal assembly. To prove the platform capabilities, we produced fluorescent and magnetic nanoassemblies composed of fluorescent silica and magnetic NPs.
