The Au nanoparticles(AuNPs) attached carbon nanotubes (Au-CNTs) were prepared and discussed their chemical, electrical properties, and sensing application. The crystallinity of the CNT phase was confirmed by analyzing the G and D bands in their Raman spectra. The electrical conductivity of the highly crystalline carbon phase of Au-CNTs (rAu-CNT = 250 nm) was ~104 S/cm. The field effect transistors (FETs) based on the Au-CNTs, which were assembled on a SiO2/Si wafer using the dielectrophoresis technique, showed that the Au-CNTs would be a good functional electronic material for future electronic and sensing applications. The transconductance and hole mobility of the FETs are 3.6 x 10-4 A/V and 3.1 x 104 cm2/Vs, respectively. Also, we have investigated AuNPs attached multiwall nanotubes(MWCNT)-FET sensors for non-enzymatic carbohydrates detection. This is a unique realization of a MWCNT based carbohydrates sensor, which does not rely on enzymes or electrochemical redox mediators to function, but rather on a combination of sensing affinity between the carbohydrate and the active part of the AuNPs-CNTs based FET.
