Discover News 80 Beats – Aleksandr Noy claims to have created “the first example of a truly integrated bioelectronic system,” New Scientist says. And as simple as the transistor is, the idea behind it—harnessing the energy already in our bodies to power electronics—will be one of the keys to creating battery-free devices that monitor our cells, connect to our brains, or do things we won’t think of until we’ve got nanodevices hooked up to our brains.
Nanoletters – Carbon Nanotube Transistor Controlled by a Biological Ion Pump Gate
We report a hybrid bionanoelectronic transistor that has a local ATP-powered protein gate. ATP-dependent activity of a membrane ion pump, Na+/K+-ATPase, embedded in a lipid membrane covering the carbon nanotube, modulates the transistor output current by up to 40%. The ion pump gates the device by shifting the pH of the water layer between the lipid bilayer and nanotube surface. This transistor is a versatile bionanoelectronic platform that can incorporate other membrane proteins.

2. University Of Utah researchers have developed a method to form pristine carbon nanotubes and graphene films without using expensive and time consuming post processing steps and systems. The graphene ribbon has a width in the range of 1 to 20 nanometers.
The University Of Utah Research Foundation, in U.S. Patent Application 20100119434, discloses methods for the formation of nanotube from thin films of graphene. The methods involve the adsorption of atoms to the surface of the films. The adsorbed atoms introduce surface stress, inducing a curvature in the films. The curvature is sufficient to bring atoms at the edges into sufficiently close proximity to form covalent bonds. Other methods include the step of desorbing the atoms from the surface of the film.”
3. Tianjin University from China has conducted research and successfully produced a kilometer long carbon nanotube fiber with excellent uniformity.
This competes with long lengths of carbon nanotube (not all one molecule) from Rice University and Nanocomp Technologies
