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.
