Modification of the Working Electrode 171
Figure 6.2 Schematics showing different configurations for modifying base
electrodes with nanoparticles for immunoassays. (a) No nanoparticles.
(b) Nanoparticles incorporated within the base electrode material. (c)
Nanoparticles deposited on the base electrode. (d) Nanoparticles included
within a composite layer on the base electrode. (e) Nanoparticles localized
on an intermediary layer. In each case, the nanoparticles, or base
electrode, may be (i) unmodified, (ii) functionalized with antibodies, or (iii)
functionalized with material(s) other than ...
