SCN / Synthesis of Colloidal Nanocrystals
The nanochemistry facility entails exploitation of elaborate colloidal chemistry approaches (ambient and high-temperature) to harness nanoscale size and shape-guiding mechanisms that afford various kinds of functional nanocrystals (single-phase, core@shell, anisotropic, hybrid particles) with tunable response (semiconducting, metallic, magnetic etc). Multidimensional nanostructures, such as cluster-like nanoarchitectures or periodic nanoparticle superlattices could also be realized by exploiting our know-how on directed assembly methods in liquid media. User-based projects benefit from controlled requirements for nanocrystal growth under anaerobic conditions met by the offered tools (e.g. Schlenk techniques, including digital temperature control growth conditions, Ar-circulating glove-boxes) that are combined with an armory of in-house characterization methods (structural, optical, electrical, dielectric, magnetic etc.). The aim is to provide a user-oriented platform for cost-efficient, easily scaled-up fabrication of novel inorganic nanoparticles, as well as their complete understanding that facilitates their use in diverse and interdisciplinary applications, from data storage and electronics to catalysis and biomedical imaging/therapy.
