Electrode gold-nanopartide-modified

Electrode surfaces can be modified with metal nanopartides and such surfaces have found numerous applications in the field of bioelectrochemistry, particularly in biosensors [7, 155]. Gold nanopartides are often utilized in such studies since they are known to retain the activity of the biomolecule with electrochemical activity intact as well [15]. It has also been observed that these nanopartides can act as conduction centers fadlitating the transfer of electrons. In addition, they provide large catalytic surface areas.
