Molecular transistors

Transistors are a key component of electronic devices. By shrinking their size to molecular level, researchers at university of Alberta & university of Liverpool have discovered a way to make faster miniaturised gadgets.
Todays faster transistors need around one million electrons to switch a current. in the new discovery, current flows through a single molecule a billionth of a metre, or nanometre, in size & only one electron is needed to make the switch.
With molecular transistors , devices like medical diagnostic eqipment could run faster & more cheaply on a smaller scale.
