abstract = "A porous electrode material combining the features of vertically
aligned multi-walled carbon nanotubes (VAMWCNT) and diamond-like
carbon films (DLC) have been developed for a highly sensitive
electrochemical sensor. For working electrode preparation, DLC has
been grown onto VAMWCNT, forming a porous, conductive and stable
composite. The electrochemical performance of this DLC:VAMWCNT
electrode has been investigated toward detection and analysis of
three well-known molecules, namely paracetamol, codeine and
caffeine. A ternary mixture of these analytes was simultaneously
determined under optimum experimental conditions using square-wave
voltammetry. Wide linear concentration ranges and the limits of
detection of 3.34x10(-7)molL(-1), 1.57x10(-7)molL(-1) and
3.67x10(-7)molL(-1) were obtained for paracetamol, codeine and
caffeine, respectively. We conclude that the proposed voltammetric
method and the DLC:VAMWCNT electrode comprise a reliable
methodology for simultaneous determination of paracetamol, codeine
and caffeine in biological matrix samples.",
