is such good news.
"The good electrochemical properties for both carbon nanotubes and platinum nanoparticles have been well documented" Dr. Jining Xie explains to Nanowerk. "However, there are few reports on combining both. The originality of our work is to in-situ prepare platinum decorated carbon nanotubes, not simple mixing them, as the supportive materials for glucose sensing electrodes."
The researchers used platinum decorated multi-walled CNTs to prepare an enzyme-based mediated glucose sensor. Compared with the bare MWNT-based sensor, the Pt/MWNT paste-based glucose sensor exhibits a substantially higher sensitivity.
Xie, a research scientist in charge of the Nanomaterials and Carbon Nanotube Laboratory at the University of Arkansas' High Density Electronics Center, points out that an obvious potential application of his team's work is for fast, sensitive and considerably reliable glucose sensing. Such precise detection of glucose level and continuous monitoring its fluctuation throughout the day could be a significant improvement of diabetes control and its management.
