Carbon Nanotube Matrices for implantable Biofuel Cell design

Holzinger M., Le Goff A., Cosnier S., CNRS - University of Grenoble, FR

Glucose biofuel cells are promising candidates to supply implanted electronic devices by converting the chemical energy of glucose, present in body fluids, into electric power. Before such biofuel cells can become realistic alternatives compared to [...]

A Helical Peptide can Mediate Electron over 120 Å by Hopping Mechanism

Arikuma Y., Nakayama H., Morita T., Kimura S., Kyoto University, JP

We have studied long-range electron transfer through various lengths of helical peptides from 8 mer (24 Å) up to 80 mer (120 Å) in self-assembled monolayers prepared on a gold surface. Helical peptides carrying a [...]

Novel Carbon Nanotube-Biomedical Polymer Composite Platforms for Bioelectrochemical Applications

Ounnunkad S., Minett A.I., Fleming B.D., Bond A.M., Wallace G.G., University of Wollongong, AU

The construction and the electrochemical characteristics of novel freestanding biomedical polymer-single walled carbon nanotube (SWCNT) nanocomposite electrode, formed via an intercalation process have been described. The intercalating polymer reinforces the Buckypaper to provide sufficient strength [...]

Visualization of quantum dot-electron donor conjugate uptake and processing by living cells

Clarke S.J., Hollmann C.A., Nadeau J.L., McGill University, CA

The interactions of semiconductor quantum dots (QDs) with living cells remain poorly understood. It is known that certain sizes (colors) of QDs penetrate more readily into subcellular compartments, such as the nucleus, or into bacteria. [...]
