- Abstract
- Arrays of palladium nanoparticles (Pd NPs) were fabricated on flexible single-walled carbon nanotube (SWCNT) films, and the fabricated Pd NPs/SWCNT films were employed as electrodes for electrochemical glucose detection. Palladium particles with an average diameter of 20-40 nm were distributed homogeneously on the SWCNT film. The Pd NPs/SWCNT electrode displayed a good detection limit of 3.4 mu M and two linear ranges for glucose concentration. Sensitivities were 313.9 +/- 4.8 mu A mM(-1) cm(-2) and 155.2 +/- 2.6 mu A mM(-1) cm(-2) respectively. Moreover, the Pd NPs/SWCNT showed high selectivity for glucose in the presence of L-ascorbic acid as an interfering compound.
