CRYSTALLISATION OF SMALL AND MONODISPERSED NANOPARTICLES VIA MICROFLUIDICS 

In order to accomplish a more sustainable and water-based synthesis of functional inorganic materials, we have recently developed a field of research concerning the microfluidic synthesis of inorganic nanocrystalline materials, in collaborations with Proff. M. Maggini and T. Carofiglio. In particular, we focussed on the room-temperature synthesis of very small and monodispersed pure and transition metal and lanthanide-doped zinc sulphide nanoparticles, without the use of any ligand and/or surfactant.[36-37]

Indeed, thanks to the unique conditions that are achieved in a microfluidic reactor, namely i) the highly efficient and fast mixing and ii) the flowing and dynamic nature of the system, a high control on the product’s size and size distribution can be achieved.

In Fig. 5 a schematic representation of our microfluidic set-up is reported.
