Resumen:
he synthesis of nanoparticle-cored dendrimers
(NCDs) through surface functionalization of iron oxide nanoparticles
(c-Fe2O3) by combining the conventional silane coupling
agent 3-(aminopropyl) triethoxysilane (APS) with
dendritic moieties is studied and presented. Much emphasis
has been put on the role played by each modifier and how
they interact not only between themselves, but also with the
dispersing media wherein the resulting NCDs are. As a part of
the functionalization, redox-active nitro groups were introduced
onto the surface of each synthesized NCD thus making
them electrochemically active. Then, the obtained NCDs were
immobilized onto glassy carbon electrodes. Both the NCDs and
modified electrodes are expected to be eventually exploited in
analytical and sensing applications
