Resumen:

In this work, a synthetic pathway was developed to obtain dendritic molecule-coated magnetic

nanoparticles. Briefly, maghemite magnetic iron oxide ( -Fe2O3)

nanoparticles NPs were modified with 3-(aminopropyl)trimethoxysilane (APS) as silane coupling agent [7].

Afterwards, dendritic molecule (D NO2) were covalently attached to the modified NPs, achieving nitrofunctionalized

magnetic nanoparticles. Infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA),

and transmission electronic microscopy (TEM) were used to characterize the derivatised surface.
