abstract = "Porous boron-doped diamond (p-BDD) electrodes were prepared and
explored as a potential electrochemical sensor for applications in
flow-injection analysis (FIA) coupled to amperometric detection
systems. Porous BDD films were grown by Hot Filament Chemical
Vapor Deposition (HFCVD) over oxygen plasma functionalized carbon
nanotubes and, morphological and chemical characterizations of the
obtained composite material were carried out by Field Emission Gun
Scanning Electron Microscopy (FEG-SEM) and Raman spectroscopy. The
analytical performance of the designed p-BDD electrode under FIA
conditions was investigated using two model electroactive
analytes, epinephrine (EP, an important neurotransmitter) and
acetaminophen (AC, a commonly consumed analgesic). All
experimental parameters, such as applied potential, flow-rate and
injection volume for both analytes were optimized. Under the best
experimental conditions, the analytical curves for EP and AC were
linear from 0.60 to 30.0 \μmol L\− 1 (EP) and from
0.80 to 70.0 \μmol L\− 1 (AC), with detection limits
of 0.50 \μmol L\− 1 and 0.70 \μmol L\− 1
for EP and AC, respectively. Measurement precision was
demonstrated from a number of amperometric measurements performed
for successive injections of standard AC and EP solutions. In
addition, the applicability of the developed FIA procedure was
reported for the AC and EP determination in human serum fluid.",
