abstract = "A novel platform for electroanalysis of isoniazid based on
graphene-functionalized multi-walled carbon nanotube as support
for iron phthalocyanine (FePc/f-MWCNT) has been developed. The
FePc/f-MWCNT composite has been dropped on glassy carbon forming
FePc/f-MWCNT/GC electrode, which is sensible for isoniazid,
decreasing substantially its oxidation potential to +200 mV vs
Ag/AgCl. Electrochemical and electroanalytical properties of the
FePc/f-MWCNT/GC-modified electrode were investigated by cyclic
voltammetry, electrochemical impedance spectroscopy, scanning
electrochemical microscopy, and amperometry. The sensor presents
better performance in 0.1 mol L\−1 phosphate buffer at pH
7.4. Under optimized conditions, a linear response range from 5 to
476 \μmol L\−1 was obtained with a limit of detection
and sensitivity of 0.56 \μmol L\−1 and 0.023
\μA L \μmol\−1, respectively. The relative
standard deviation for 10 determinations of 100 \μmol
L\−1 isoniazid was 2.5%. The sensor was successfully
applied for isoniazid selective determination in simulated body
fluids.",
