Selective formation of only one iron
oxide phase is a major challenge
in conventional laser ablation process, as is scaling up the process.
Herein, superparamagnetic single-phase magnetite nanoparticles of
hexagonal and spheroidal-shape, with an average size of ca. 15 nm,
are generated by laser ablation of bulk iron metal at 1064 nm in a
vortex fluidic device (VFD). This is a one-step continuous flow process,
in air at ambient pressure, with in situ uptake of the nanoparticles
in the dynamic thin film of water in the VFD. The process minimizes
the generation of waste by avoiding the need for any chemicals or
surfactants and avoids time-consuming purification steps in reducing
any negative impact of the processing on the environment.
