Microscopic characterization of nanoAu-GEC electrodes.
Microphotographs showing the distribution of gold nanoparticles on the
surface of nanoAu-GEC electrodes while increasing the amount of gold
nanoparticles from 0 to 100% of the conductive phase. First column, low-
resolution (100

with thiol and fluorescein. Third column, stereomicroscopy without the flu-
orescence filter (Fig. 3.8, third column). See also Color Insert.
