Electrochemical sensing based on gold nanoparticle-decorated halloysite nanotube composites. Analytical biochemistry, 2012, Nov-15, Volume: 430, Issue:2 Novel gold nanoparticle-decorated halloysite nanotube (AuNP-HNT) composites were effectively synthesized and then used for electrochemical sensing applications. The AuNP-HNT nanocomposites were characterized by transmission electron microscopy, field emission scanning electron microscopy, zeta potential, and UV-Vis spectroscopy. The AuNP-HNT composite-based modified electrode exhibited high eletrocatalytic activity to the reduction of hydrogen peroxide (H(2)O(2)) with a linear range of 5.0×10(-6) to 2.55×10(-4)M and a detection limit of 1×10(-6)M (signal/noise=3), indicating that it could be used as a novel nonenzymatic electrochemical H(2)O(2) sensor. Furthermore, the Ru(bpy)(3)(2+)/AuNP-HNT/Nafion composite film modified electrode exhibited good electrochemiluminescence activity for determining tripropylamine.

Electrochemiluminescence from hydrophilic thin film Ru(bpy)3(2+)-modified electrode prepared using natural halloysite nanotubes and polyacrylamide gel. Biosensors & bioelectronics, 2009, May-15, Volume: 24, Issue:9 Because Ru(bpy)(3)(2+)-modified electrodes are often used in aqueous condition, the development of a hydrophilic modified electrode is of critical importance. Herein a hydrophilic, thin film Ru(bpy)(3)(2+)-modified electrode is successfully developed using polyacrylamide gel to embed halloysite nanotubes on the electrode surface which is used to adsorb Ru(bpy)(3)(2+) by cation-exchange. X-ray photoelectron spectroscopy demonstrates the formation of the film on an electrode and the high adsorbing capacity of the halloysite nanotubes toward Ru(bpy)(3)(2+). The different electrochemiluminescence (ECL) behaviors of the electrode using nitrilotriacetic acid and tripropylamine, as co-reactants, illustrate the hydrophilic character of the modified electrode. Contrary to the previous works, the addition of carbon nanotubes into the modified electrode film leads to a decreased ECL emission, due to the reduction in the porosity of the film, which hinders the diffusion of the analyte.
