Proving it is possible to use biology to create electronics, scientists at the Technion-Israel Institute of Technology have harnessed the power of DNA to create a self-assembling nanoscale transistor, the building block of electronics.

Multilevel molecular memory

17 March, 2004

In conventional memory cells a bit of information is either a zero or one.(In hypothetical quantum computers, a bit could be both a zero and a one at the same time, but that kind of nimble balancing is years away from exploitation and so bits continue to be bi-level.) In the meantime one way of cramming more data into a fixed lateral region on a data storage device, other than shrinking the cell's size, is to store more than one bit in each memory cell. This is one goal of molecular electronics (or moletronics) where, for instance one would like to store information in the form of parcels of charge placed at several active sites around a single molecule.
