To recapitulate, Bi was deposited onto the GC from 2mM Bi perchlorate in 0.1 M [H.sub.2]S[O.sub.4] using chronocoulometry at -0.1V versus SCE.
The bimetallic catalyst was prepared by a two-step process using chronocoulometry in a way that controlled the amount of Bi that was electrodeposited onto glassy carbon followed by electrodeposition of Pt layer [28].
For this experiment, 20 [micro]L of the cell lysate containing 8.0 -260 ng of protein was placed on an electrode with the ETS primer immobilized to 70 fmol/[cm.sup.2] (4.9 fmol) as measured by chronocoulometry using RuHex (10).
The ratios Red:Ox determined by spectrometry and chronocoulometry as a function of electrode potentials were indistinguishable [8].

The films were electrochemically conditioned by the chronocoulometry method in order to change the inorganic ions in the films and have them be familiar with a LiCI[O.sub.4]/PC environment (12).
His major achievements were the development of chronocoulometry to measure charge density at solid electrode surfaces and in situ photon polarization infrared reflection spectroscopy to study thin organic films at electrode surfaces.
However, the necessity, of creating a rough, and not well-characterized, surface to activate SERS is a major impediment when seeking to correlate SERS intensity with surface coverage; the latter is obtained from a smooth clean surface by chronocoulometry.[9] Alexandre Brolo (PhD student) has developed a new procedure to obtain data from electrochemically smooth electrodes: measurements were made for different degrees of surface roughness (tracked by AFM), as obtained by increasing numbers of ORCs, and intensities were extrapolated to zero ORC.
