Abstract(s)
A nanohybrid electrochemical transducer surface was developed using carbon and gold nanomaterials. The strategy
relayed on casting multiwalled carbon nanotubes or carbon nanofibers onto a screen-printed carbon electrode surface,
followed by in situ generation of gold nanoparticles by electrochemical deposition of ionic gold, in a reproducible
manner. These transducers, so fabricated, were characterized using both electrochemical and microscopic techniques.
Biofunctionality was evaluated using the streptavidin-biotin interaction system as the biological reaction
model. These platforms allow to achieve low detection limits (in the order of pmoles), are reproducible and stable
at least for a month after their preparation, being a perfect candidate to be used as transducer of different sensor
devices.
