Part-human, part-machine transistor devised Discovery News, June 2, 2010
University of California, Merced scientists have embedded a carbon nanotube-based transistor inside a lipid bilayer (cell-like membrane) and powered it with an ion pump and a solution of adenosine triphosphate (ATP) to fuel the ion pump.
The research could lead to new types of man-machine interactions where embedded devices could relay information about the inner workings of disease-related proteins or toxins inside the cell membrane, and eventually even treat diseases. It could also lead to new ways to read, and even influence, brain or nerve cells.
