Resumen:
The spontaneous adsorption of the dendron 3,5-Bis (3,5-dinitrobenzoylamino)
benzoic acid (D-NO2) onto gold and carbon electrodes produced conductive
surfaces with electroactive chemical functions. A comparative electrochemical
behavior of both electrodes after dendron immobilization led us to conclude that
the self-assembly of D-NO2 on carbon is faster and stronger. Considering this
advantage, the surface of magnetic maghemite nanoparticles (MNPs) was modified
using D-NO2. Firstly, MNPs were modified with APS as silane coupling agent and
afterwards, D-NO2 was covalently attached to the surface, achieving nitro-functionalized
MNPs. Subsequently, the immobilization of these modified MNPs onto glassy
carbon surfaces was explored to generate a novel platform promising for biosensors
development.2) onto gold and carbon electrodes produced conductive
