Abstract

A simple continuous-flow liquid-phase approach for the partial coating of nanoscale particles with metal was established [1]. Unique to this is the surface conformal and morphology-tailored growth of the metal. Due to their anisotropic surface character, the resulting materials are potentially relevant as particulate surfactants or for the assembly of novel photonic, catalytic or theranostic materials. In this contribution, three significant challenges are described that have recently been tackled. Firstly, it is shown how the use of a KM type micromixer with very short characteristic mixing times facilitates the understanding of the metal coating growth process. Secondly, the application of multiwavelength analytical ultracentrifugation for the determination of yield, coating thickness, and coverage distribution of the metal patches is considered. The validity of the measurements through microscopy and spectroscopy is confirmed and it is demonstrated how this characterization method can be employed to support process design. Finally, it is illustrated how the continuous flow approach can be developed in order to produce anisotropic metal-coated particles on the gram scale, and a first analysis of the novel optical properties of the powders is provided.
