Sabrina Staasmeyer, M.Sc.
The research of Sabrina Staasmeyer is focused on the tailored integration of noble metal nanoparticles into microgels for the development of novel colloidal catalysts, optical sensors and imaging and diagnostic tools. The chemical design of the polymer chains in the microgel interior allows control of the in-situ growth of gold nanoparticles (AuNPs) and modulation of their size, shape and localisation in microgel. The mechanism and kinetics of nanoparticles formation in microgels are investigated with UV-vis spectroscopy, light scattering methods and electron microscopy. This approach allows synthesis of microgels with single gold cores or microgels with multiple gold and palladium nanoparticles, variable NPs loading and excellent colloidal stability in water and organic solvents. Synthesised hybrid microgels are promising building blocks for optical sensors, efficient catalysts for the hydrogenation reactions and imaging agents for the cancer diagnostics.
