Molecular Transistor
A science team at the University of Liverpool has demonstrated that a single molecule can serve as a transistor.
The team tested the transistor potential of a molecule by using the electrostatic field emanating from a single atom to regulate the conductivity of a molecule, allowing an electric current to flow through the molecule. These effects were easily observed at room temperature, in contrast to previous molecular experiments that had to be conducted at temperatures close to absolute zero...
The molecules involved are organic rather than silicone. New devices made with this technology would be smaller, faster, cheaper and...biodegradable!
Perhaps "smaller" is the wrong word; maybe "device" is the wrong word too. Once this technology matures, molecular electronics would literally disappear into everyday objects. You wouldn't even think of these things as electronic devices. The world would just wake up - everything smarter all around us.
